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

Exciton polaritons, the part-light and part-matter quasiparticles in semiconductor optical
cavities, are promising for exploring Bose–Einstein condensation, non-equilibrium many …

Topological physics relies on the structure of the eigenstates of the Hamiltonians. The
geometry of the eigenstates is encoded in the quantum geometric tensor—comprising the …

Layered materials can be assembled vertically to fabricate a new class of van der Waals
heterostructures a few atomic layers thick, compatible with a wide range of substrates and …

Quantum fluids exhibit quantum mechanical effects at the macroscopic level, which contrast
strongly with classical fluids. Gain-dissipative solid-state exciton-polaritons systems are …

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

Inverse Anderson transitions, where the flat-band localization is destroyed by disorder, have
been wildly investigated in quantum and classical systems in the presence of Abelian gauge …

Topological physics relies on Hamiltonian's eigenstate singularities carrying topological
charges, such as Dirac points, and–in non-Hermitian systems–exceptional points (EPs) …

Spin-orbit interactions lead to distinctive functionalities in photonic systems. They exploit the
analogy between the quantum mechanical description of a complex electronic spin-orbit …
