Brane order and quantum magnetism in modulated anisotropic ladders
Toplal Pandey, Gennady Y. Chitov
Two-leg spin- ladders with anisotropy and two different dimerization patterns are analyzed at zero temperature. This model is equivalent to a modulated interacting (Kitaev…
Phase diagram and topological order in the modulated chain with magnetic fields
Toplal Pandey, Gennady Y. Chitov
The antiferromagnetic spin- chain with alternation of the exchange and anisotropy couplings in the presence of uniform and staggered axial magnetic fields is studied. Th…
String and conventional order parameters in the solvable modulated quantum chain
Gennady Y. Chitov, Toplal Pandey, P. N. Timonin
The phase diagram and the order parameters of the exactly solvable quantum 1D model are analysed. The model in its spin representation is the dimerized XY spin chain in the presenc…
Constructing Landau framework for topological order: Quantum chains and ladders
Gennady Y. Chitov, Toplal Pandey
We studied quantum phase transitions in the antiferromagnetic dimerized spin-1/2 XY chain andvtwo-leg ladders. From analysis of several spin models we present our main result: the…
