Temperature-induced optical enhancement near a localization transition
Raul Liquito, Miguel Gonçalves, Bruno Amorim +1
Quasiperiodic systems are an intermediate class of systems between periodic crystals and disordered systems, famously exhibiting metal-insulator transitions (MITs) even in one dime…
Effective band-projected description of interacting quasiperiodic systems
Flavio Riche, Raul Liquito, Bruno Amorim +3
We study the interplay between electronic interactions and quasiperiodicity in a one-dimensional narrow-band system, focusing on ground-state and low-energy excitation properties.…
Local Density of States as a Probe of Multifractality in Quasiperiodic Moiré Materials
Ricardo Oliveira, Nicolau Sobrosa, Pedro Ribeiro +2
Quasiperiodic moiré materials provide a new platform for realizing critical electronic states, yet a direct and experimentally practical method to characterize this criticality has…
Ground state and excitations of quasiperiodic 1D narrow-band moiré systems: a mean field approach
Nicolau Sobrosa, Miguel Gonçalves, Bruno Amorim +2
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…
Semiconductor Wannier equations: a real-time, real-space approach to the nonlinear optical response in crystals (ATATA)
Eduardo B. Molinero, Bruno Amorim, Misha Ivanov +6
We develop the semiconductor Wannier equations (SWEs), a real-time, real-space formulation of ultrafast light-matter dynamics in crystals, by deriving the equations of motion for t…
Exact nonlinear dynamics of single band metallic systems with dissipation: From optical to dc currents
J. M. Alendouro Pinho, B. Amorim, Yuliy V. Bludov +1
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…
