Amplitude mode in two-dimensional coherent spectroscopy of weak-coupling antiferromagnets
Jiyu Chen, Naoto Tsuji, Philipp Werner
Two-dimensional coherent spectroscopy (2DCS) provides insights into the nonlinear response of correlated lattice systems. We simulate multipulse excitations in the Hubbard model us…

2D coherent spectroscopy signatures of exciton condensation in TaNiSe
Jiyu Chen, Jernej Mravlje, Denis Golež +1
We show that the nonlinear optical response probed by two-dimensional coherent spectroscopy (2DCS) can discriminate between excitonic and lattice driven order. In the excitonic reg…

Steady-state dynamical mean field theory based on influence functional matrix product states
Mithilesh Nayak, Julian Thoenniss, Michael Sonner +2
We implement the recently developed influence functional matrix product states approach as impurity solver in equilibrium and nonequilibrium dynamical mean field theory (DMFT) calc…
