Spin modulations in the Rashba-Hubbard chain -- a tensor network study
Jozef Genzor, Roman Krčmár, 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…
Energy Scale Deformation on Regular Polyhedra
Takuya Eguchi, Satoshi Oga, Hosho Katsura +2
A variant of energy scale deformation is considered for the S = 1/2 antiferromagnetic Heisenberg model on polyhedra. The deformation is induced by the perturbations to the uniform…
Magnetization processes and existence of reentrant phase transitions in coupled spin-electron model on doubly decorated planar lattices
Hana Čenčariková, Jozef Strečka, Andrej Gendiar
An alternative model for a description of magnetization processes in coupled 2D spin-electron systems has been introduced and rigorously examined using the generalized decoration-i…
The influence of further-neighbor spin-spin interaction on a ground state of 2D coupled spin-electron model in a magnetic field
Hana Čenčariková, Jozef Strečka, Andrej Gendiar +1
An exhaustive ground-state analysis of extended two-dimensional (2D) correlated spin-electron model consisting of the Ising spins localized on nodal lattice sites and mobile electr…
Suppression of finite-size effects in one-dimensional correlated systems
A. Gendiar, M. Daniska, Y. Lee +1
We investigate the effect of a non-uniform deformation applied to one-dimensional (1D) quantum systems, where the local energy scale is proportional to de…
The large system asymptotics of persistent currents in mesoscopic quantum rings
A. Gendiar, R. Krcmar, M. Weyrauch
We consider a one-dimensional mesoscopic quantum ring filled with spinless electrons and threaded by a magnetic flux, which carries a persistent current at zero temperature. The in…
