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…
Efficient Magnetic Spin-Filtering and Persistent Spin-Currents in Lifshitz-Transitioned Altermagnets: A Route to Open-Orbit Spintronics
Wun-Hao Kang, Yu-Ting Hsiao, Jozef Genzor +3
Altermagnets offer a unique venue for spin transport due to their vanishing net magnetization and momentum-dependent spin splitting. We demonstrate that a homotopic Lifshitz transi…
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…
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…
