Superconductivity of Bad Fermions: Origin of Two Gaps in HTSC Cuprates
E. A. Stepanov, S. Iskakov, M. I. Katsnelson +1
We investigate the spectral properties of the doped Hubbard model with parameters typical for high-temperature cuprate superconductors. Our approach is based on a novel st…
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…
Role of three-particle vertex within dual fermion calculations
T. Ribic, P. Gunacker, S. Iskakov +5
We investigate the influence of self-energy diagrams beyond the two-particle vertex level within dual fermion theory. Specifically, we calculate the local three-particle vertex and…
Local Plaquette Physics as Key Ingredient of High-Temperature Superconductivity in Cuprates
M. Danilov, E. G. C. P. van Loon, S. Brener +3
A major pathway towards understanding complex systems is given by exactly solvable reference systems that contain the essential physics of the system. For the Hubbard mode…
Updated Core Libraries of the ALPS Project
A. Gaenko, A. E. Antipov, G. Carcassi +16
The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice…
