Publication date: Available online 6 February 2019Source: Physics ReportsAuthor(s): Yupeng Zhang, Chang-Keun Lim, Zhigao Dai, Guannan Yu, Joseph W. Haus, Han Zhang, Paras N. PrasadAbstractThis review focuses on the physics of optical excitation dynamics, band gap engineering and charge carrier dynamics in metal-halide perovskites and their organic hybrids as well as on their technological applications. The role of plasmonic coupling and photonic cavities in enhancing light-matter interactions and manipulating carrier dynamics is clearly presented by examples of studies of perovskite-hybrid plasmonic nanostructured perovski...

Quadratic mean field games
Publication date: Available online 21 January 2019Source: Physics ReportsAuthor(s): Denis Ullmo, Igor Swiecicki, Thierry GobronAbstractMean field games were introduced independently by J-M. Lasry and P-L. Lions, and by M. Huang, R.P. Malhamé and P.E. Caines, in order to bring a new approach to optimization problems with a large number of interacting agents. The description of such models split in two parts, one describing the evolution of the density of players in some parameter space, the other the value of a cost functional each player tries to minimize for himself, anticipating on the rational behavior of the others.Qu...

Ultra-high-energy cosmic rays
In this report we review the important progress made in recent years towards understanding the experimental data on ultra-high-energy (E≳109GeV) cosmic rays. We begin with a general survey of the available data, including a description of the energy spectrum, the nuclear composition, and the distribution of arrival directions. At this point we also give a synopsis of experimental techniques. After that, we introduce the fundamentals of cosmic ray acceleration and energy loss during propagation, with a view of discussing the conjectured nearby sources. Next, we survey the state of the art regarding the high- and ultra-hig...

A systematic approach to generalisations of General Relativity and their cosmological implications
Publication date: Available online 4 January 2019Source: Physics ReportsAuthor(s): Lavinia HeisenbergAbstractA century ago, Einstein formulated his elegant and elaborate theory of General Relativity, which has so far withstood a multitude of empirical tests with remarkable success. Notwithstanding the triumphs of Einstein’s theory, the tenacious challenges of modern cosmology and of particle physics have motivated the exploration of further generalised theories of spacetime. Even though Einstein’s interpretation of gravity in terms of the curvature of spacetime is commonly adopted, the assignment of geometrical concept...

Non-geometric backgrounds in string theory
Publication date: Available online 24 December 2018Source: Physics ReportsAuthor(s): Erik PlauschinnAbstractThis review provides an introduction to non-geometric backgrounds in string theory. Starting from a discussion of T-duality, geometric and non-geometric torus-fibrations are reviewed, generalised geometry and its relation to non-geometric backgrounds are explained and compactifications of string theory with geometric and non-geometric fluxes are discussed. Furthermore covered are doubled geometry as well as non-commutative and non-associative structures in the context of non-geometric backgrounds. (Source: Physics Reports)

Classification, geometry and applications of supersymmetric backgrounds
We describe in detail the geometry of backgrounds of key supergravity theories, which have applications in the context of black holes, string theory, M-theory and the AdS/CFT correspondence unveiling a plethora of existence and uniqueness theorems. Some other aspects of supersymmetric solutions like the Killing superalgebras and the homogeneity theorem are also presented, and the non-existence theorem for certain smooth supergravity flux compactifications is outlined. Amongst the applications described is the proof of the emergence of conformal symmetry near black hole horizons and the classification of warped AdS backgrou...
