General pairing theory for condensed and non-condensed pairs of a superconductor in a high magnetic field
Peter Scherpelz, Dan Wulin, Břetislav Šopík +2
We extend Gor'kov theory to address superconducting pairing at high magnetic fields and general temperatures with arbitrary attractive interaction strength. This analysis begins wi…
Quantumness of correlations and entanglement
A. R. Usha Devi, A. K. Rajagopal, Sudha
Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correl…
Quantum dynamical maps and Markovianity
A. R. Usha Devi, A. K. Rajagopal, Sudha
It is known that the time evolution of a subsystem from an initial state to two later times, t1, t2 (t2 > t1), are both completely positive (CP) but it is shown here that in the in…
Majorana representation of symmetric multiqubit states
A. R. Usha Devi, Sudha, A. K. Rajagopal
As early as 1932, Majorana had proposed that a pure permutation symmetric state of N spin- 1 2 particles can be represented by N spinors, which correspond geometrically to N points…
