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…
