Quantum Phase Transitions in Spin-1/2 Ising Chain in Regularly Alternating Transverse Field: Spin Correlation Functions
Oleg Derzhko, Taras Krokhmalskii
We consider the spin-1/2 Ising chain in a regularly alternating transverse field to examine the effects of regular alternation on the quantum phase transition inherent in the quant…

Quantum phase transition in a transverse Ising chain with regularly varying parameters
O. Derzhko, J. Richter, T. Krokhmalskii +1
Using rigorous analytical analysis and exact numerical data for the spin-1/2 transverse Ising chain we discuss the effects of regular alternation of the Hamiltonian parameters on t…

Spatial decay of the one-body density matrix in insulators revised
Janusz Jedrzejewski, Taras Krokhmalskii
In the framework of the band theory, we consider two tight-binding models of insulators. The first one, proposed recently by Taraskin et al, is a translationally invariant system,…
