Abstract: Motivated by recent work suggesting observably large spacetime fluctuations in the causal development of an empty region of flat space, we conjecture that these metric fluctuations can be quantitatively described in terms of a conformal… read more here.

Abstract: Noncommutative optical squeezed vacuum states are constructed as eigenstates of an appropriate two-photon annihilation operator corresponding to the Biedenharn–Macfarlane q-oscillator. We consider ... read more here.

DOI: 10.1142/s021974991850003x
Abstract: In this paper, by using the parity operator as well as the two-mode squeezing operator, we define new operators which by the action of them on the vacuum state of the two-mode radiation field, superposition… read more here.
