A time-based Chern number in periodically-driven systems in the adiabatic limit
I-Te Lu, Dongbin Shin, Umberto De Giovannini +4
To define the topology of driven systems, recent works have proposed synthetic dimensions as a way to uncover the underlying parameter space of topological invariants. Using time a…

Electronic dispersion, correlations and stacking in the photoexcited state of 1T-TaS
Jingwei Dong, Dongbin Shin, Ernest Pastor +11
Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
