Revisiting the - Heisenberg Model on a Triangular Lattice: Quasidegenerate Ground States and Phase Competition
Oleksandra Kovalska, Ester Pagès Fontanella, Benedikt Schneider +2
It is generally believed that the spin- triangular-lattice - Heisenberg model hosts a quantum spin liquid in the intermediate regime between the …
Adaptive Patching for Tensor Train Computations
Gianluca Grosso, Marc K. Ritter, Stefan Rohshap +5
Quantics Tensor Train (QTT) operations such as matrix product operator contractions are prohibitively expensive for large bond dimensions. We propose an adaptive patching scheme th…
Subleading logarithmic behavior in the parquet formalism
Marcel Gievers, Richard Schmidt, Jan von Delft +1
The Fermi-edge singularity in x-ray absorption spectra of metals is a paradigmatic case of a logarithmically divergent perturbation series. Prior work has thoroughly analyzed the l…
Two-particle calculations with quantics tensor trains: Solving the parquet equations
Stefan Rohshap, Marc K. Ritter, Hiroshi Shinaoka +3
We present the first application of quantics tensor trains (QTTs) and tensor cross interpolation (TCI) to the solution of a full set of self-consistent equations for multivariate f…
Nonequilibrium steady-state thermoelectrics of Kondo-correlated quantum dots
Anand Manaparambil, Andreas Weichselbaum, Jan von Delft +1
The transport across a Kondo-correlated quantum dot coupled to two leads with independent temperatures and chemical potentials is studied using a controlled non-perturbative, and i…
Differentiating Hund from Mott physics in a three-band Hubbard-Hund model: Temperature dependence of spectral, transport, and thermodynamic properties
K. M. Stadler, G. Kotliar, S. -S. B. Lee +2
We study the interplay between Mott physics, driven by Coulomb repulsion U, and Hund physics, driven by Hund's coupling J, for a minimal model for Hund metals, the orbital-symmetri…
