Local Density of States as a Probe of Multifractality in Quasiperiodic Moiré Materials Open
Quasiperiodic moiré materials provide a new platform for realizing critical electronic states, yet a direct and experimentally practical method to characterize this criticality has been lacking. We show that a multifractal analysis of the …

Exact solution for the current generated by dissipative master equation in single-band tight-binding systems subject to time-dependent uniform electric fields Open
The theory of open quantum systems is one of the most essential tools for the development of quantum technologies. A particular area of interest is in the optical response of solid state systems, where dissipation is introduced phenomenolo…

Ground state and excitations of quasiperiodic 1D narrow-band moiré systems: a mean field approach Open
We demonstrate that a mean field approximation can be confidently employed in quasiperiodic moiré systems to treat interactions and quasiperiodicity on equal footing. We obtain the mean field phase diagram for an illustrative one-dimension…

Subcycle dynamics of excitons under strong laser fields Open
Excitons play a key role in the linear optical response of two-dimensional (2D) materials. However, their role in the nonlinear response to intense, nonresonant, low-frequency light is often overlooked as strong fields are expected to tear…

Formation, stability, and highly nonlinear optical response of excitons to intense light fields interacting with two-dimensional materials Open
Excitons play a key role in the linear optical response of 2D materials. However, their significance in the highly nonlinear optical response to intense mid-infrared light has often been overlooked. Using hBN as a prototypical example, we …
