Magnetically activated optical visibility of many-body excitons in NiPS
Shuta Matsuura, Shohei Imai, Naoto Tsuji
NiPS is a layered van der Waals magnet that provides a unique platform for exploring the interplay between excitons and magnetic order. In its antiferromagnetic phase, strong m…
Weak-coupling tensor cross interpolation impurity solver for nonequilibrium dynamical mean-field theory
Shuta Matsuura, Hiroshi Shinaoka, Philipp Werner +1
Simulating nonequilibrium quantum many-body systems remains a major challenge due to the exponential growth of the computational complexity with real time. Here we implement a none…
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…
Tensor cross interpolation approach for quantum impurity problems based on the weak-coupling expansion
Shuta Matsuura, Hiroshi Shinaoka, Philipp Werner +1
We apply the tensor cross interpolation (TCI) algorithm to solve equilibrium quantum impurity problems with high precision based on the weak-coupling expansion. The TCI algorithm,…
Nonequilibrium DMFT approach to time-resolved Raman spectroscopy
Philipp Werner, Martin Eckstein, Naoto Tsuji
Raman spectroscopy uses light scattering to extract information on low-energy excitations of solids. The Raman process is described by diagrams which are fourth order in the light-…
Nonequilibrium dynamical mean-field theory based on weak-coupling perturbation expansions: Application to dynamical symmetry breaking in the Hubbard model
Naoto Tsuji, Philipp Werner
We discuss the general formalism and validity of weak-coupling perturbation theory as an impurity solver for nonequilibrium dynamical mean-field theory. The method is implemented a…
