Near-field radiative heat transfer in many-body systems

Author(s): S.-A. Biehs, R. Messina, P. S. Venkataram, A. W. Rodriguez, J. C. Cuevas, and P. Ben-AbdallahNear-field radiative heat transfer refers to the transport of thermal energy by electromagnetic radiation between objects separated by less than a thermal wavelength. It involves tunneling processes that can lead to large deviations from Planck’s...

Equilibrium mechanisms of self-limiting assembly

Author(s): Michael F. Hagan and Gregory M. GrasonSelf-assembly is a process in which multiple building blocks spontaneously organize into collective and coherent ordered structures. This process is ubiquitous in soft synthetic and biological systems with examples ranging from lipid membranes, surfactant micelles, virus capsids, and bilayer vesicles...

Vector bosons and jets in proton collisions

Author(s): Paolo Azzurri, Marek Schönherr, and Alessandro TricoliEvents with vector bosons produced in association with jets have been studied at hadron colliders and provide high-accuracy tests of the standard model. A good understanding of these processes is of paramount importance for precision measurements, including Higgs physics, and for searches...

Circuit quantum electrodynamics

Author(s): Alexandre Blais, Arne L. Grimsmo, S. M. Girvin, and Andreas WallraffThis review surveys the development over the last 15 years of circuit quantum electrodynamics, the nonlinear quantum optics of microwave electrical circuits. In analogy to cavity quantum electrodynamics, lasers are replaced by rf signal generators, optical cavities by superconducting...

Emergent constraints on climate sensitivities

Author(s): Mark S. Williamson, Chad W. Thackeray, Peter M. Cox, Alex Hall, Chris Huntingford, and Femke J. M. M. NijsseEmergent constraints (ECs) relate observables of the climate system to equivalent quantities simulated from Earth system models that are related to properties of the future climate. The uncertainties in projections of these properties...

Finite-temperature transport in one-dimensional quantum lattice models

Author(s): B. Bertini, F. Heidrich-Meisner, C. Karrasch, T. Prosen, R. Steinigeweg, and M. ŽnidaričOne-dimensional models of interacting electrons have long served as a testing ground for theoretical and numerical methods. More recently they have become directly relevant for interpreting experiments on spin chains, and ultracold quantum gases. This...

Experimental perspective on three-dimensional topological semimetals

Author(s): B. Q. Lv, T. Qian, and H. DingA confluence of precise theoretical predictions shows that carefully fabricated three-dimensional (3D) semimetals can host a variety of exotic phases dominated by topological constraints. This experimental review of 3D topological semimetals addresses the role that electronic structure and associated band crossings...

Simulation methods for open quantum many-body systems

Author(s): Hendrik Weimer, Augustine Kshetrimayum, and Román OrúsThis article reviews theoretical methods to deal with interacting quantum particles that are in contact with their environment and are thus described by a master equation rather than a Schrödinger equation. The similarities and differences are discussed between the pursuit of pure many-body...
