Driving Floquet physics with excitonic fields

Floquet engineering is often limited by weak light–matter coupling and heating. Now it is shown that exciton-driven fields in monolayer semiconductors produce stronger, longer-lived Floquet effects and reveal hybridization linked to excitonic phases.

Orbital textures and evolution of correlated insulating state in monolayer 1T phase transition metal dichalcogenides

Transition metal compounds provide a versatile platform for tailoring Mott physics. Here, the authors reveal that hybridization between the lower Hubbard band and the chalcogen band stabilizes the Mott state through bandwidth tuning in the 1T-MX₂ (M = Nb, Ta; X = S, Se) family.

Strongly enhanced shift current at exciton resonances in a noncentrosymmetric wide-gap semiconductor

Quantum geometry effects in condensed matter physics are a topic of growing interest. Here, the authors show that the quantum geometry associated with excitons can generate detectable shift currents in a wide-gap semiconductor.

Observation of possible excitonic charge density waves and metal–insulator transitions in atomically thin semimetals

The mechanism of charge density wave formation has been hard to explain due to accompanying structural distortions. Now low-dimensional HfTe₂ is revealed to host a purely electronic exitonic charge density wave driven by reduced screening effects.

Evidence of high-temperature exciton condensation in a two-dimensional semimetal

Two-dimensional materials are promising platforms for the realization of an excitonic insulator state. Here the authors report evidence for an excitonic insulator in a single-layer ZrTe2 based on ARPES measurements.

Many-body enhancement of high-harmonic generation in monolayer MoS₂

Many-body effects may be crucial for describing high harmonic generation in solids, but previous work did not fully account for many-body effects. Here the authors develop a non-perturbative, ab initio theory and apply it to monolayer MoS2, showing significant many-body effects in the perpendicular response.

Intralayer charge-transfer moiré excitons in van der Waals superlattices

By combining large-scale first-principles GW-BSE calculations and micro-reflection spectroscopy, the nature of the exciton resonances in WSe₂/WS₂ moiré superlattices is identified, highlighting non-trivial exciton states and suggesting new ways of tuning many-body physics.
