The ALPS project release 3.0: open source software for strongly correlated systems
F. Alet, T. Chen, A. Feiguin +16
We present release 3.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open-source software project to develop libraries and application programs for the…
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…
Magnetic phases of the anisotropic triangular lattice Hubbard model
Yang Yu, Shaozhi Li, Sergei Iskakov +1
The Hubbard model on an anisotropic triangular lattice in two dimensions, a fundamental model for frustrated electron physics, displays a wide variety of phases and phase transitio…
Robust analytic continuation of Green's functions via projection, pole estimation, and semidefinite relaxation
Zhen Huang, Emanuel Gull, Lin Lin
Green's functions of fermions are described by matrix-valued Herglotz-Nevanlinna functions. Since analytic continuation is fundamentally an ill-posed problem, the causal space desc…
Single- and two-particle finite size effects in interacting lattice systems
Sergei Iskakov, Hanna Terletska, Emanuel Gull
Simulations of extended quantum systems are typically performed by extrapolating results of a sequence of finite-system-size simulations to the thermodynamic limit. In the quantum…
