Since the discovery of topological insulators, many topological phases have been predicted
and realized in a range of different systems, providing both fascinating physics and exciting …

Asymmetric coupling amplitudes effectively create an imaginary gauge field, which induces
a non-Hermitian Aharonov-Bohm (AB) effect. Nonzero imaginary magnetic flux invalidates …

We propose a realistic cold-atom quantum setting where topological localization induces
nonreciprocal pum**. This is an intriguing non-Hermitian phenomenon that illustrates how …

Cold atoms with laser-induced spin-orbit (SO) interactions provide a platform to explore
quantum physics beyond natural conditions of solids. Here we propose and experimentally …

This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

We present the first experimental observation of a topological transition in a non-Hermitian
system. In contrast to standard methods for examining topological properties, which involve …

Gauge fields are central in our modern understanding of physics at all scales. At the highest
energy scales known, the microscopic universe is governed by particles interacting with …

Weyl semimetals are three-dimensional (3D) gapless topological phases with Weyl cones in
the bulk band. According to lattice theory, Weyl cones must come in pairs, with the minimum …

Artificial gauge fields are currently realized in a wide range of physical settings. This
includes solid-state devices but also engineered systems, such as photonic crystals …
