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…
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…
Quantum Potts Models on the SierpiÅski Pyramid
Roman KrÄmár, Mária Zelenayová, Jozef Genzor +4
Phase transition of the two- and three-state quantum Potts models on the SierpiÅski pyramid are studied by means of a tensor network framework, the higher-order tensor renormaliza…
