Defect production and quench dynamics in the three-dimensional Kitaev model
Subhajit Sarkar, Dibyendu Rana, Saptarshi Mandal
We study the quench dynamics of the three-dimensional Kitaev (spin) model under a linear drive using both exact numerical calculations and analytical "independent crossing approxim…
Fermi surface instabilities of symmetry-breaking and topological types on the surface of a three-dimensional topological insulator
Subhajit Sarkar
The emergence of the Pomeranchuk instability (PI) in a Helical Fermi liquid (HFL) residing on the surface of a three-dimensional topological insulator (3D TI) is addressed at the m…
Delocalization of charge and current in a chiral quasiparticle wave-packet
Subhajit Sarkar
A chiral quasi-particle wave packet (c-QPWP) is defined as a conventional superposition of chiral quasi-particle states corresponding to an interacting electron system in two dimen…
Semi-phenomenological analysis of neutron scattering results for quasi-two dimensional quantum anti-ferromagnet
Subhajit Sarkar, Ranjan Chaudhury, Samir K. Paul
The available results from the inelastic neutron scattering experiment performed on the quasi-two dimensional spin anti-ferromagnetic material have been…
The connection between vortex-like topological excitations and conventional excitations in quantum ferromagnetic spin systems on two dimensional lattice and their stability
Subhajit Sarkar, Ranjan Chaudhury, Samir K. Paul
We present a scheme for the construction of quantum states of vortex like topological excitations corresponding to spin- 1/2 strongly XY anisotropic nearest neighbor Heisenberg Fer…
