Thermoelectric transport in the topological phase due to the coexistence of superconductivity and spin-density-wave
Amit Gupta, Debanand Sa
We study the thermoelectric transport in two dimensional topological system which has coexistence of superconductivity(SC) and spin-density wave(SDW). The SC is presumed to be of $…
Topological phase in a superconductor in presence of spin-density-wave
Amit Gupta, Debanand Sa
We consider a mean-field Hamiltonian for a superconductor(SC) in presence of spin-density-wave(SDW) order. This is due to the fact that the non-commutativity o…
Topological phases due to the coexistence of superconductivity and spin-density wave: Application to high Tc superconductors in the underdoped regime
Amit Gupta, Debanand Sa
We consider the coexistence of superconductivity(SC) and spin-density wave(SDW). The SC is presumed to be of type whereas the SDW order paramet…
Is LiPdB a self-doped hole superconductor ?
Manas Sardar, Debanand Sa
We propose that the electrons responsible for superconductivity in Li2Pd3B come from the palladium 4d-electrons. So, its electronic properties are likely to be dominated by strong…
Superconductivity in NaCoOyHO : Is Spin-Charge Separation Protecting a d+id State ?
Debanand Sa, Manas Sardar, G. Baskaran
Superconductivity in NaCoOyHO is likely to be a p or d-wave; however, experiments are unable to pinpoint the symmetry. A simple estimate of pair breaking effects…
Hidden Quantum Critical Point in a Ferromagnetic Superconductor
Debanand Sa
We consider a coexistence phase of both Ferromagnetism and superconductivity and solve the self-consistent mean-field equations at zero temperature. The superconducting gap is show…
Pairbreaking Without Magnetic Impurities in Disordered Superconductors
Amit K. Chattopadhyay, Richard A. Klemm, Debanand Sa
We study analytically the effects of inhomogeneous pairing interactions in short coherence length superconductors, using a spatially varying Bogoliubov-deGennes model. Within the B…
