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…

Logarithmic delocalization of end spins in the S=3/2 antiferromagnetic Heisenberg chain

Gabor Fath, Ors Legeza, Peter Lajko +1

Using the DMRG method we calculate the surface spin correlation function, $C_{L} (l) =< S_{l}^{z} S_{L + 1 - l}^{z} >$ , in the spin $S = 3/2$ antiferromagnetic Heisenberg chain. For comparison we a…
