Quench dynamics in topologically non-trivial quantum many-body systems
Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2
We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…

Scaling of energy and power in a large quantum battery-charger model
Lei Gao, Chen Cheng, Wen-Bin He +3
We investigate a multi-qubit quantum battery-charger model, focusing on its potential emulation on a superconducting qubit chip. Using a large-spin representation, we first obtain…
