Unwithered Majorana fermions in the bulk of a quantum chain
Gennady Y. Chitov
The proposal is to probe Majorana modes in the system when its parameters are tuned to bring it into a disentangled ground state, which occur on the parametric curves known as diso…
Disentanglement, disorder lines, and Majorana edge states in a solvable quantum chain
Gennady Y. Chitov, Karun Gadge, P. N. Timonin
We study the exactly solvable 1D model: the dimerized chain with uniform and staggered transverse fields, equivalent upon fermionization to the noninteracting dimerized Kitaev…
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…
Disorder lines, modulation, and partition function zeros in free fermion models
P. N. Timonin, Gennady Y. Chitov
The modulation is analyzed from the analytical properties of zeros of free fermionic partition function on the complex plane of wave numbers. It is shown how these properties are r…
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…
Mass varying neutrinos with different quintessence potentials
Sayan Mandal, Gennady Y. Chitov, Olga Avsajanishvili +2
The mass-varying neutrino scenario is analyzed for three trial quintessence potentials (Ferreira-Joyce, inverse exponential, and thawing oscillating). The neutrino mass is generate…
