Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

We review the development of random-matrix theory (RMT) during the last fifteen years. We
emphasize both the theoretical aspects, and the application of the theory to a number of …

We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic)
meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising …

Weyl semimetals are a class of materials that can be regarded as three-dimensional
analogs of graphene upon breaking time-reversal or inversion symmetry. Electrons in a …

The development of classical and quantum information–processing technology calls for on-
chip integrated sources of structured light. Although integrated vortex microlasers have been …

A quantal system in an eigenstate, slowly transported round a circuit C by varying
parameters R in its Hamiltonian Ĥ (R), will acquire a geometrical phase factor exp {iγ (C)} in …

The distinction between level clustering and level repulsion is one of the quantum
analogues of the classical distinction between globally regular and predominantly chaotic …

We show that the fundamental time-reversal invariant (TRI) insulator exists in 4+ 1
dimensions, where the effective-field theory is described by the (4+ 1)-dimensional Chern …

Nanomagnetism is a rapidly expanding area of research which appears to be able to
provide novel applications. Magnetic molecules are at the very bottom of the possible size of …

There are fundamental relations between three vast areas of physics: particle physics,
cosmology and condensed matter physics. The fundamental links between the first two …
