Pairing symmetries in the Zeeman-coupled extended attractive Hubbard model
Swagatam Nayak, Navketan Batra, Sanjeev Kumar
By introducing the possibility of equal- and opposite-spin pairings concurrently, we show that the extended attractive Hubbard model (EAHM) exhibits rich ground state phase diagram…
Topological Transitions in a Model for Proximity Induced Superconductivity
Navketan Batra, Swagatam Nayak, Sanjeev Kumar
Using a prototype model for proximity induced superconductivity on a bilayer square lattice, we show that interlayer tunneling can drive change in topology of the Bogoliubov quasip…
Exotic Superconductivity in the Extended Attractive Hubbard Model
Swagatam Nayak, Sanjeev Kumar
We show that the extended attractive Hubbard model on a square lattice hosts a variety of superconducting phases, including exotic mixed-symmetry phases with $d_{x^2-y^2} + {\rm i}…
Transient domain walls and lepton asymmetry in the Left-Right symmetric model
J. M. Cline, U. A. Yajnik, S. N. Nayak +1
It is shown that the dynamics of domain walls in Left-Right symmetric models, separating respective regions of unbroken SU(2)_L and SU(2)_R in the early universe, can give rise to…
Baryogenesis through axion domain wall
S. N. Nayak, U. A. Yajnik
Generic axion models give rise to axion domain walls in the early Universe and they have to disappear not to overclose the universe, thus limiting the nature of discrete symmetry a…
Thermal Effects on Two-photon Decays of Pseudo-scalars
Sourendu Gupta, S. N. Nayak
We study the effect of finite temperatures and Fermion density on the effective pseudo-scalar-photon vertex induced by the triangle diagram. The manifestly covariant calculations s…
