The current understanding of the role of topology in non-Hermitian (NH) systems and its far-
reaching physical consequences observable in a range of dissipative settings are reviewed …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

Nonlinear topological photonics is an emerging field that aims to extend the fascinating
properties of topological states to a regime where interactions between the system …

In this Letter, we study the conditions under which on-site dissipations can induce non-
Hermitian skin modes in non-Hermitian systems. When the original Hermitian Hamiltonian …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

Topology is central to understanding and engineering materials that display robust physical
phenomena immune to imperfections. Different topological phases of matter are …

The notion of non-Hermitian optics and photonics rooted in quantum mechanics and
photonic systems has recently attracted considerable attention ushering in tremendous …

Non-Hermitian Hamiltonians provide an alternative perspective on the dynamics of quantum
and classical systems coupled non-conservatively to an environment. Once primarily an …

Microcavity polaritons are light-matter quasiparticles that arise from the strong coupling
between excitons and photons confined in a semiconductor microcavity. They are typically …

The non-Hermitian skin effect (NHSE), which involves an extensive number of bulk modes
collapsing to open boundaries as skin modes, unveils a variety of unprecedented …
