Abstract: We consider a harmonic oscillator coupled to a Markovian environment, i.e. a thermal reservoir. We derive the Keldysh path integral and the corresponding lesser, greater, time-ordered, antitime-ordered, retarded, advanced, and Keldysh Green’s functions for this… read more here.

Abstract: Abstract Three classes of generalized supercoherent states have been recently introduced, degenerate, singular and generic. We have studied the entanglement, squeezing and statistical properties of these supercoherent states. Using concurrence, we calculate the entanglement of… read more here.

DOI: 10.1016/j.ijleo.2019.163845
Abstract: Abstract Multiphoton supercoherent states are defined as eigenstates of m-th power of supersymmetric annihilation operator, where m is a positive integer. In this paper, we study the entanglement of such states. To this purpose, we… read more here.
