Enhanced Multifractality Induced by Non-Hermitian Disorder in Quantum Percolation
W. S. Oliveira, Julian Faundez, Rodrigo Arouca +1
We investigate the interplay between geometric dilution and non-Hermitian disorder in the two-dimensional quantum site-percolation model. Non-Hermiticity is introduced through rand…
Enhancement of charge correlations and real-space topological marker on an interacting non-Hermitian Su-Schrieffer-Heeger model
Sebastião dos A. Sousa-Júnior, Pedro B. Melo, Rubem Mondaini +2
We investigate the interacting non-Hermitian Su-Schrieffer-Heeger (SSH) model, focusing on the interplay between topology and charge ordering. Using a real-space topological marker…
Hall conductance in a weakly time-reversal invariant open system
Alexander Fagerlund, Christopher Ekman, Rodrigo Arouca
The quantum Hall effect and the quantum anomalous Hall effect both require time-reversal invariance to be broken. We show that non-equilibrium effects can cause Hall physics to ari…
Real-Space Imaging of Moiré-Confined Excitons in Twisted Bilayer MoS
Laurens J. M. Westenberg, Lumen Eek, Jort D. Verbakel +8
Twisted two-dimensional semiconductors generate a moiré landscape that confines excitons (bound electron-hole pairs) into programmable lattices, offering routes to efficient light…
Quantum Field Theory Anomalies in Condensed Matter Physics
R. Arouca, Andrea Cappelli, T. H. Hansson
We give a pedagogical introduction to quantum anomalies, how they are calculated using various methods, and why they are important in condensed matter theory. We discuss axial, chi…
Superconducting and Pseudogap Transition Temperatures in High-Tc Cuprates and the Dependence on Pressure
E. C. Marino, Reginaldo O. Corrêa, R. Arouca +2
We derive analytic expressions for the critical temperatures of the superconducting (SC) and pseudogap (PG) transitions of the high-Tc cuprates as a function of doping. These are i…
