TRIQS/Nevanlinna: Implementation of the Nevanlinna Analytic Continuation method for noise-free data
Sergei Iskakov, Alexander Hampel, Nils Wentzell +1
We present the TRIQS/Nevanlinna analytic continuation package, an efficient implementation of the methods proposed by J. Fei et al in [Phys. Rev. Lett. 126, 056402 (2021)] and [Phy…
Heating and cooling in self-consistent many-body simulations
Yang Yu, Sergei Iskakov, Emanuel Gull
We present a temperature extrapolation technique for self-consistent many-body methods, which provides a causal starting point for converging to a solution at a target temperature.…
A Tensor Train Continuous Time Solver for Quantum Impurity Models
A. Erpenbeck, W. -T. Lin, T. Blommel +8
The simulation of strongly correlated quantum impurity models is a significant challenge in modern condensed matter physics that has multiple important applications. Thus far, the…
Perturbative solution of fermionic sign problem in lattice Quantum Monte Carlo
Sergei Iskakov, Mikhail I. Katsnelson, Alexander I. Lichtenstein
We develop a strong-coupling perturbation scheme for a generic Hubbard model around a half-filled particle-hole-symmetric reference system, which is free from the fermionic sign pr…
