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…
Observation of end-to-end pumping in a quasiperiodic Fibonacci-type photonic chain
Arnob Kumar Ghosh, Ang Chen, Ashraf El Hassan +3
Topological pumps offer a promising route to operate as connecting buses, supplying efficient and robust connectivity between non-neighboring elements in a network. Here, we invest…
Laser-induced topological phases in monolayer amorphous carbon
Arnob Kumar Ghosh, Quentin Marsal, Annica M. Black-Schaffer
Driving non-topological materials out of equilibrium using time-periodic perturbations, such as circularly-polarized laser light, is a compelling way to engineer topological phases…
Topology and energy dependence of Majorana bound states in a photonic cavity
Aksel KobiaÅka, Arnob Kumar Ghosh, Rodrigo Arouca +1
Light-matter interaction plays a crucial role in modifying the properties of quantum materials. In this work, we investigate the effect of cavity induced photon fields on a topolog…
