Entropic analysis of quantum phase transitions from uniform to spatially inhomogeneous phases

Ö. Legeza, J. Sólyom, L. Tincani +1

We propose a new approach to study quantum phase transitions in low-dimensional fermionic or spin models that go from uniform to spatially inhomogeneous phases such as dimerized, t…

Mott transition and dimerization in the one-dimensional SU $(n)$ Hubbard model

K. Buchta, Ö. Legeza, E. Szirmai +1

The one-dimensional SU $(n)$ Hubbard model is investigated numerically for $n = 2, 3, 4$ , and 5 at half filling and $1/ n$ 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 $n$ -component fermionic fields in the chains has been considered using an analytic renormalization group method. The fixed points and possible phases have bee…
