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 …

Interactions between quasiparticles mediated by a surrounding environment are ubiquitous
and lead to a range of important effects from collective modes of low-temperature quantum …

Since the discovery of two-dimensional transition metal dichalcogenide monolayers as
direct bandgap semiconductors with pronounced room-temperature exciton transitions …

The elementary optical excitations in two-dimensional semiconductors hosting itinerant
electrons are attractive and repulsive polarons—excitons that are dynamically screened by …

The coexistence of correlated electron and hole crystals enables the realization of quantum
excitonic states, capable of hosting counterflow superfluidity and topological orders with …

We report evidence that ferromagnetic order in electrostatically doped, monolayer transition
metal dichalcogenide (TMD) semiconductors can be stabilized and controlled at zero …

Strongly interacting electronic systems often exhibit a complicated phase diagram that
results from the competition between different quantum ground states. One feature of these …

Moiré heterostructures of transition metal dichalcogenides (TMDs) exhibit Mott-insulating
behavior both at half filling as well as at fractional fillings, where electronic degrees of …

In this paper, the optical absorption coefficients (OACs) and the refractive index changes
(RICs) due to both intra-and inter-band transitions in monolayer WS 2 are theoretically …

Time-dependent spin-density functional theory (TD-SDFT) allows the theoretical description
of spin and magnetization dynamics in electronic systems from first principles. TD-SDFT …
