Magnetism in two-dimensional (2D) van der Waals (vdW) materials has recently emerged as
one of the most promising areas in condensed matter research, with many exciting emerging …

Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary
excitations of a many-particle background. In the field of ultracold atoms, the study of the …

Two-dimensional materials and their heterostructures constitute a promising platform to
study correlated electronic states, as well as the many-body physics of excitons. Transport …

When the Coulomb repulsion between electrons dominates over their kinetic energy,
electrons in two-dimensional systems are predicted to spontaneously break continuous …

One of the first theoretically predicted manifestations of strong interactions in many-electron
systems was the Wigner crystal,–, in which electrons crystallize into a regular lattice. The …

Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly
correlated materials such as cuprates originate from Coulomb exchange interactions. The …

Two-dimensional moiré superlattices provide a highly tunable platform to study strongly
correlated physics. In particular, the moiré superlattices of two-dimensional semiconductor …

Confining particles to distances below their de Broglie wavelength discretizes their motional
state. This fundamental effect is observed in many physical systems, ranging from electrons …

In recent years, active metasurfaces have emerged as a reconfigurable nanophotonic
platform for the manipulation of light. Here, application of an external stimulus to resonant …

Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …
