This makes these materials interesting from both fundamental and applied perspectives. This Colloquium explains recent progress in the experimental characterization and theoretical understanding as well as their potential for device applications.
Particle accelerators have been engines of discovery for many decades. The most powerful ones are used in particle physics where intense particle beams collide to study new particles. This has led to groundbreaking discoveries in our understanding of matter and forces. In this article the key concepts behind the development of such colliders are reviewed and a historical perspective is provided of the evolution of these machines.
Approaches for next-generation colliders are presented and technology developments for far-future colliders that will have the further benefit of enabling new applications in the use of accelerators for science and society are discussed. Quantum systems that are coupled to an external bath can often be described in terms of a non-Hermitian effective Hamiltonian.
In isolated systems with Hermitian Hamiltonians, topological aspects of the band structure, and resulting topological phases, have been of interest. The combination of the two concepts, i.
This review provides an introduction to these quantum mechanical concepts and their classical analogs, and discusses a number of applications ranging from mechanical metamaterials to dissipative cold-atom systems. Originally hypothesized to explain the absence of C P violation in the strong interactions, the axion has emerged as a candidate constituent of dark matter.
This review guides the reader through the search methods for the QCD axion as well as for new kinds of particles with axionlike properties. For each case, the physics of the method, the signatures, and the background are discussed in depth. A must-have addition to the quiver of axion hunters. Modern instruments and observational programs in astrophysics and cosmology have opened new perspectives for probing general relativity on previously unexplored scales.
This review provides both a methodological and an observational survey of the constraints on modified-gravity models using astrophysical objects in the cosmological, weak-field regime. It is embedded in the framework of the novel probes project, a forum connecting observers and theorists involved in the study of astrophysical tests of dark sector interactions. The rapid neutron-capture process plays a major role in the production of heavy elements from Fe to U.
This review surveys the history and current understanding of r -process nucleosynthesis, covering new data from atomic and nuclear physics, astrophysical modeling of r -process sites, astronomical observations of stellar abundances, and galactic chemical evolution. It includes a timely and thorough discussion of plausible r -process astrophysical environments, following the first multimessenger observation of a binary neutron-star merger.
Though one might guess that observation of surface oscillatory motions would be limited to our Sun, high-precision brightness measurements of distant stars, performed over many years, have enabled the field of asteroseismology.
This comprehensive review covers the recent development of this field, the necessary blending of numerical simulation and data, and the way in which this new information enhances our understanding of stellar evolution. Efforts to understand the character of the neutrino, and searches for physics beyond the standard model, motivate several ongoing experiments to detect neutrinoless double-beta decay.
The complementary process of double-electron capture has received less attention. Currently the limits on capture measurements are not competitive with the limits on decay measurements.
With a look to future experiments, this review covers the current status, emphasizes the significant enhancements that can occur when a resonance condition exists, and provides a road map for future progress. The measured neutrino spectrum is essential in this epoch of multimessenger astronomy. To explore astrophysics and particle physics it is necessary to understand and quantify the known contributions to the grand unified neutrino spectrum.
Only through a study of the expected neutrino backgrounds can we hope to detect new phenomena. This review summarizes the composition of the spectrum arising from the cosmic background, the remnants of nucleosynthesis, solar and terrestrial production, supernovae and cosmological phenomena, and even nuclear power plants.
Bosonic helium is one of the most quantum mechanical materials ever studied in physics. It shows the famous Bose-Einstein condensation at extremely low temperatures. Although the equilibrium properties of boson liquids are now well understood, little is known about their nonequilibrium properties, especially the interfacial properties between superfluid and crystal phases far from equilibrium.
In this Colloquium nonequilibrium crystal shapes in superfluid are discussed based on high-speed visualization techniques and the challenges related to the theoretical interpretation of the interfacial dynamics are presented.
Taking the limit of a large number of spatial dimensions is a familiar technique in statistical mechanics but, until recently, seldom used in gravity. These include the classic singularity theorems of Penrose and Hawking, which imply that under certain rather general conditions singularities are unavoidable. Light rays play an important role in the proofs of these theorems.
This paper reviews the properties of light rays and surveys their implications for the occurrence of singularities in general relativity. Parton distribution functions quantify the nonperturbative QCD structure of protons and nuclei, expressed as probabilities for finding quarks and gluons, in high-energy collisions.
Determined by applying advanced quantum field theory to precise experimental measurements using modern statistical techniques, parton distribution functions are crucial for interpreting the short-distance behavior of the standard model.
This review presents the state of the art of this evolving subject. At low temperatures, atoms in classical crystals are localized at lattice sites and can be regarded as distinguishable particles rendering quantum statistics unimportant. This review covers the concepts and properties of solid helium and how crystalline properties are affected by structure, defects, vacancies, and dislocations.
Recent experimental results on plastic deformation give promise to a new understanding of the mechanical properties of quantum solids. The question of how classical systems approach thermal equilibrium is as old as the foundations of thermodynamics and statistical mechanics.
How quantum systems decohere and thermalize is even more puzzling. This Colloquium provides an account of how the thermal equilibrium of a system is influenced by the presence of a thermal bath. It also gives a view of both classical and quantum aspects providing an understanding on the particularities of the quantum case. Moreover, a description of the challenges in the definition of heat from the perspective of fluctuating thermodynamical potentials is given. An old subject, perhaps, but definitely fundamental.
This contribution was invited in conjunction with this award. The motion in its interior is complex and involves diverse physical phenomena at many scales, from nuclear to astronomical. In this Colloquium the unusual flow of mass and energy inside the convective region of our yellow star is discussed. These papers are the text of the address given in conjunction with the award.
Quantum states of light are at the same time endowed with two superposition principles: the one of the classical Maxwell waves and the one of the quantum states occupying these waves. This article reviews the interplay between these two aspects of quantum optics. A summary of the description of multimode quantum states is presented along with an example of the characterization of correlations and entanglement with applications in metrology and quantum computation.
Modeling and controlling the flow of complex fluids with nanoscale resolution is an essential component of current and future technologies. In particular, electric fields can be effectively used to steer and manipulate polymeric solutions to create new materials and devices. This review outlines the rich physics of fluid mechanics, electromagnetism, and polymer dynamics that combine to create the theoretical underpinnings of this burgeoning field.

The following is a list of notable unsolved problems grouped into broad areas of physics. Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail. There are still some questions beyond the Standard Model of physics , such as the strong CP problem , neutrino mass , matter—antimatter asymmetry , and the nature of dark matter and dark energy.
In this course we will learn how to distill scientific knowledge from experimental data, a process that relies on statistical methods. We will learn the basics concepts of Probability and Statistics in their Frequentist and Bayesian frameworks. In addition, we will study and practice several particular statistical methods and data analysis techniques usually used in the fields of High Energy Physics, Astrophysics and Cosmology.
This book is aimed at students who have completed a final year undergraduate course on general relativity and supplemented it with additional techniques by individual study or in a taught MSc This book is aimed at students who have completed a final year undergraduate course on general relativity and supplemented it with additional techniques by individual study or in a taught MSc programme. The additional technical knowledge required involves the Cartan calculus, the tetrad formalism including aspects of the Newman—Penrose formalism, the Ehlers—Sachs theory of null geodesic congruences, and the Petrov classification of gravitational fields. Each chapter could be used as a basis for an advanced undergraduate or early postgraduate project. The topics covered fall under three general headings: Gravitational waves in vacuo and in a cosmological setting, equations of motion with particular emphasis on spinning particles, and black holes. These are not individual applications of the techniques mentioned above.
