Spin modulations in the Rashba-Hubbard chain -- a tensor network study
Jozef Genzor, Roman KrÄmár, Andrej Gendiar +2
Uniform spin-orbit coupling in an open single-band Hubbard chain is an exactly removable \(SU(2)\) gauge field at the Hamiltonian level, but not at the level of laboratory-frame sp…
Entanglement-entropy analysis of critical and topological quantum phases in a frustrated spin-1/2 Heisenberg ladder
Azadeh Ghannadan, Hana Vargová, Jozef Genzor +2
We investigate the ground-state phase diagram of a frustrated spin-1/2 Heisenberg ladder in the transverse magnetic field with an anisotropic inter-rung exchange coupling . Thi…
Magnetic Field Induced by Straight Currents on the Hyperboloid
Roman Krcmar, Andrej Gendiar, Tomotoshi Nishino
We consider the magnetic field induced by the steady or the quasi-steady electric currents that flow along the straight wires, which are equidistantly arranged on the hyperboloid.…
Tensor-Network study of Ising model on infinite hyperbolic dodecahedral lattice
Matej Mosko, Andrej Gendiar
We propose a tensor-network-based algorithm to study the classical Ising model on an infinitely large hyperbolic lattice with a regular 3D tesselation of identical dodecahedra. We…
Phase Transition of the Ising Model on a 3-Dimensional Fractal Lattice
Jozef Genzor, Roman KrÄmár, Hiroshi Ueda +3
The critical behavior of the classical Ising model on a three-dimensional fractal lattice with Hausdorff dimension is investigated using the higher-order…
Tensor network calculation of boundary and corner magnetization
Roman Krcmar, Jozef Genzor, Andrej Gendiar +1
The Corner Transfer Matrix Renormalization Group (CTMRG) algorithm is modified to measure the magnetization at the boundary of the system, including the corners of the square-shape…
