Quantics tensor cross interpolation for high-order strong-coupling expansions
Kanghyeon Kim, Lei Geng, Philipp Werner +1
Real-time impurity solvers enable the study of transport phenomena and the description of nonequilibrium lattice systems within the framework of dynamical mean-field theory (DMFT).…
-pairing in metallic and particle-hole asymmetric systems
Philipp Werner, Aaram J. Kim, Lei Geng
Light-induced superconducting-like states have been reported in several classes of correlated materials. From a theoretical point of view, the induction of -pairing is a promisi…
High-temperature -pairing superconductivity in the photodoped Hubbard model
Lei Geng, Aaram J. Kim, Philipp Werner
We investigate superconductivity emerging in the photodoped Mott insulating Hubbard model using steady-state dynamical mean-field theory implemented on the real-frequency axis. By…
Strange diffusivity of incoherent metal in half-filled two-dimensional Hubbard model
Youngmin Eom, Igor S. Tupitsyn, Nikolay V. Prokof'ev +3
We study charge transport across the metal-insulator crossover in the half-filled two-dimensional Hubbard model, with particular emphasis on precision control. The dynamic current-…
Third-order strong-coupling impurity solver for real-frequency DMFT: Accurate spectral functions for antiferromagnetic and photo-doped states
Lei Geng, Aaram J. Kim, Philipp Werner
We present a real-frequency third-order strong-coupling impurity solver which employs quantics tensor cross interpolation (QTCI) for an efficient evaluation of the diagram weights.…
Strong coupling impurity solver based on quantics tensor cross interpolation
Aaram J. Kim, Philipp Werner
Numerical methods capable of handling nonequilibrium impurity models are essential for the study of transport problems and the solution of the nonequilibrium dynamical mean field t…
