Competing Valence Bond States of Spin-3/2 Fermions on a Strongly Coupled Ladder
Edina Szirmai, Heloise Nonne
We study the possible ground state configurations of two strongly coupled chains of charge neutral spin-3/2 fermionic atoms interacting via short range van der Waals interaction. T…
The Role of the Exchange Interaction in the One-Dimensional -Component Hubbard Model
E. Szirmai, Ö. Legeza, J. Sólyom
The commensurate -filled -component Hubbard chain was investigated by bosonization and high-precision density-matrix renormalization-group analysis. It was found that depen…
Phase diagram of the t-U-J1-J2 chain at half filling
X. Huang, E. Szirmai, F. Gebhard +2
We investigate the half-filled Hubbard chain with additional nearest- and next-nearest-neighbor spin exchange, J1 and J2, using bosonization and the density-matrix renormalization…
Spatially nonuniform phases in the one-dimensional SU(n) Hubbard model for commensurate fillings
E. Szirmai, Ö. Legeza, J. Sólyom
The one-dimensional repulsive SU Hubbard model is investigated analytically by bosonization approach and numerically using the density-matrix renormalization-group (DMRG) meth…
Mott transition and dimerization in the one-dimensional SU Hubbard model
K. Buchta, Ö. Legeza, E. Szirmai +1
The one-dimensional SU Hubbard model is investigated numerically for , and 5 at half filling and filling using the density-matrix renormalization-group (DMRG) m…
Possible phases of two coupled n-component fermionic chains
E. Szirmai, J. Sólyom
A two-leg ladder with -component fermionic fields in the chains has been considered using an analytic renormalization group method. The fixed points and possible phases have bee…
