Dynamic properties of the spin-1/2 XY chain with three-site interactions
Taras Krokhmalskii, Oleg Derzhko, Joachim Stolze +1
We consider a spin-1/2 XY chain in a transverse (z) field with multi-site interactions. The additional terms introduced into the Hamiltonian involve products of spin components rel…
On the nature of striped phases: Striped phases as a stage of "melting" of 2D crystals
Volodymyr Derzhko, Janusz Jedrzejewski, Taras Krokhmalskii
We discuss striped phases as a state of matter intermediate between two extreme states: a crystalline state and a segregated state. We argue that this state is very sensitive to we…
Dynamic properties of quantum spin chains: Simple route to complex behavior
Taras Verkholyak, Oleg Derzhko, Taras Krokhmalskii +1
We examine dynamic structure factors of spin-1/2 chains with nearest-neighbor interactions of XX and Dzyaloshinskii-Moriya type, and with periodic and random changes in the sign of…
