Layered materials can be assembled vertically to fabricate a new class of van der Waals (VDW) heterostructures few atomic layers thick, compatible with wide range substrates and optoelectronic device geometries, enabling strategies for control light-matter coupling.

We report an extended family of spin textures zero-dimensional exciton-polaritons spatially confined in tunable open microcavity structures. The transverse-electric--transverse-magnetic (TE-TM) splitting, which is enhanced the cavity structures, leads to polariton eigenstates carrying quantized vortices. Depending on strength and anisotropy confining potential TE-TM induced can be tuned via excitonic or photonic fractions, exciton-polariton emissions exhibit either spin-vortex-like patterns...
The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both Berry curvature, central to description topological matter and metric. So far full QGT has been measured only Hermitian systems, where role metric mostly shown determine corrections physical effects. On contrary, non-Hermitian particular near exceptional points, expected diverge often play a dominant role, for example on enhanced sensing wave packet dynamics. In this work, we report...
