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…
Driving collective current excitations using light: The two-time approach
Chin Shen Ong, Denis Golež, Angel Rubio +2
We identify a distinct transverse collective excitation, which we name the "curron", arising from current-current interactions in a driven quantum metal. Unlike plasmons, which inv…
Comparing the generalized Kadanoff-Baym ansatz with the full Kadanoff-Baym equations for an excitonic insulator out of equilibrium
Riku Tuovinen, Denis Golež, Martin Eckstein +1
We investigate out-of-equilibrium dynamics in an excitonic insulator (EI) with a finite momentum pairing perturbed by a laser-pulse excitation and a sudden coupling to fermionic ba…
Adiabatic Preparation of a Correlated Symmetry-Broken Initial State with the Generalized Kadanoff--Baym Ansatz
Riku Tuovinen, Denis Golež, Michael Schüler +3
A fast time propagation method for nonequilibrium Green's functions based on the generalized Kadanoff--Baym Ansatz (GKBA) is applied to a lattice system with a symmetry-broken equi…
