Quantum metric and localization in a quasicrystal
Quentin Marsal, Patric Holmvall, Annica M. Black-Schaffer
We use the quantum metric to understand the properties of quasicrystals, represented by the one-dimensional (1D) Fibonacci chain. We show that the quantum metric can relate the loc…

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…

Probing Topological Stability with Nonlocal Quantum Geometric Markers
Quentin Marsal, Hui Liu, Emil J. Bergholtz +1
Spatially resolved local quantum geometric markers play a crucial role in the diagnosis of topological phases without long-range translational symmetry, including amorphous systems…
