Fractal Quasicondensation in One Dimension
Flavio Riche, Miguel Gonçalves, Bruno Amorim +2
We unveil a novel mechanism for quasicondensation of hard-core bosons in the presence of quasiperiodicity-induced multifractal single-particle states. The new critical state, here…
Formation, stability, and highly nonlinear optical response of excitons to intense light fields interacting with two-dimensional materials
Eduardo B. Molinero, Bruno Amorim, Mikhail Malakhov +6
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 ofte…
Incommensurability enabled quasi-fractal order in 1D narrow-band moiré systems
Miguel Gonçalves, Bruno Amorim, Flavio Riche +2
We demonstrate that quasiperiodicity can radically change the ground state properties of 1D moiré systems with respect to their periodic counterparts. By studying an illustrative e…
Short-range interactions are irrelevant at the quasiperiodic-driven Luttinger Liquid to Anderson Glass transition
Miguel Gonçalves, Jedediah H. Pixley, Bruno Amorim +2
We show that short-range interactions are irrelevant around gapless ground-state delocalization-localization transitions driven by quasiperiodicity in interacting fermionic chains.…
Quasiperiodicity-induced enhancement of superconductivity in one-dimensional critical systems
Ricardo Oliveira, Miguel Gonçalves, Pedro Ribeiro +2
We show that quasiperiodicity can enhance superconductivity in one-dimensional narrow-band systems with s-wave pairing. Using a generalized Aubry-André-Harper model featuring quasi…
