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…
Ultrafast Electronic Structure Engineering in 1-TaS: Role of Doping and Amplitude Mode Dynamics
J. Jayabalan, Jiyu Chen, Laura Pätzold +12
In strongly correlated transition metal dichalcogenides, an intricate interplay of polaronic distortions, stacking arrangement, and electronic correlations determines the nature of…
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…
Multidimensional coherent spectroscopy of correlated lattice systems
Jiyu Chen, Philipp Werner
Multidimensional coherent spectroscopy (MDCS) has been established in quantum chemistry as a powerful tool for studying the nonlinear response and nonequilibrium dynamics of molecu…
Photo-induced insulator-metal transition in paramagnetic (VCr)O
Jiyu Chen, Francesco Petocchi, Viktor Christiansson +1
Pump-probe experiments with femtosecond time resolution allow to disentangle the electronic dynamics from the lattice response and thus provide valuable insights into the non-equil…
Nature of the photo-induced metallic state in monoclinic VO
Jiyu Chen, Francesco Petocchi, Viktor Christiansson +1
The metal-insulator transition of VO, which in equilibrium is associated with a structural phase transition, has been intensively studied for decades. In particular, it is chal…
