Quantum Heisenberg antiferromagnet in a field on the Tasaki square lattice
Maksym Parymuda, Taras Krokhmalskii, Oleg Derzhko
We consider the Heisenberg antiferromagnet on the Tasaki square lattice (flat-band spin system) and study its low-temperature thermodynamics around the saturation magnetic…
Out-of-time ordered correlation functions for the localized electrons in the Falicov-Kimball model
A. M. Shvaika, J. K. Freericks
We provide an exact evaluation of the out-of-time correlation (OTOC) functions for the localized -particle states in the Falicov-Kimball model within dynamical mean-field theory…
Three-dimensional unfrustrated and frustrated quantum Heisenberg magnets. Specific heat study
T. Krokhmalskii, T. Hutak, O. Derzhko
We examine the Heisenberg magnet on four three-dimensional lattices - simple-cubic, diamond, pyrochlore, and hyperkagome ones - for ferromagnetic and antiferromagnetic sign…
Thermodynamics of the hyperkagome-lattice Heisenberg ferromagnet
Maksym Parymuda, Taras Krokhmalskii, Oleg Derzhko
The hyperkagome-lattice Heisenberg ferromagnet is studied by means of the linear spin-wave theory, the double-time temperature Green's function method, high-temperature exp…
Longitudinal magnon transport properties in the easy-axis XXZ Heisenberg ferromagnet on the face-centered cubic lattice
M. R. Parymuda
We present a detailed investigation of longitudinal magneto-thermal transport in the ferromagnetic XXZ model with easy-axis exchange anisotropy () on a face-centered c…
The Luttinger Count is the Homotopy not the Physical Charge: Generalized Anomalies Characterize Non-Fermi Liquids
Gabriele La Nave, Jinchao Zhao, Philip W. Phillips
We show that the Luttinger-Ward functional can be formulated as an operator insertion in the path integral and hence can be thought of as a generalized symmetry. The key result is…
Expressivity of determinantal ansatzes for neural network wave functions
Ni Zhan, William A. Wheeler, Gil Goldshlager +3
Neural network wave functions have shown promise as a way to achieve high accuracy on the many-body quantum problem. These wave functions most commonly use a determinant or sum of…
The finite-difference parquet method: Enhanced electron-paramagnon scattering opens a pseudogap
Jae-Mo Lihm, Dominik Kiese, Seung-Sup B. Lee +1
We present the finite-difference parquet method that greatly improves the applicability and accuracy of two-particle correlation approaches to interacting electron systems. This me…
Frustrated kagome-lattice bilayer quantum Heisenberg antiferromagnet
Dmytro Yaremchuk, Taras Hutak, Vasyl Baliha +4
We consider the antiferromagnetic Heisenberg model on a frustrated kagome-lattice bilayer with strong nearest-neighbor interlayer coupling and examine its low-temperature m…
