Metal–Organic Framework‐Based Materials for Dielectric Energy Storage

Advanced Physics Research, Volume 5, Issue 1, January 2026.
This review explores the structural design of metal–organic frameworks (MOFs) for high‐performance dielectric energy storage applications. By analyzing systems from homogeneous and heterogeneous to stimuli‐responsive and conductive, it fundamentally connects diverse framework topologies to core polarization and charge dynamics.

Polaritonic quantum matter

Nanophotonics, Volume 14, Issue 23, Page 3723-3760, 02 November 2025.
Abstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...
