Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

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 past 30 years have witnessed remarkable developments of microcavity exciton–
polaritons, which have made a great impact on photonics and optoelectronics from …

We study gap solitons which appear in the topological gap of 1D bosonic dimer chains
within the mean-field approximation. We find that such solitons have a nontrivial texture of …

We study Bogoliubov excitations of a spinor Bose-Einstein condensate in a honeycomb
periodic potential, in the presence of a Zeeman field and of a spin-orbit coupling specific for …

In recent research, it has been shown that non-Hermitian systems exhibit sensitivity to
boundaries, and it is caused by the non-Hermitian skin effect. In this work, we construct the …

We consider theoretically staggered honeycomb lattices for photons which can be viewed as
photonic analogs of transitional metal dichalcogenide (TMD) monolayers. We propose a …

Topological phase transitions, which have fascinated generations of physicists, are always
demarcated by gap closures. In this work, we propose very simple two-dimensional photonic …

We propose magnonic analogs of topological crystalline insulators which possess Dirac
surface states protected by the combined symmetry of time reversal and half translation …

In electronic topological Dirac semimetals (DSMs) the conduction and valence bands touch
at discrete points in the Brillouin zone and form Dirac cones. They are robust against spin …
