Though the celebrated spin echoes have been widely used to reverse quantum dynamics,
they are not applicable to systems whose constituents are beyond the control of the su (2) …

The impulsive generation of two-magnon modes in antiferromagnets by femtosecond optical
pulses, so-called femto-nanomagnons, leads to coherent longitudinal oscillations of the …

This survey article gives an elementary introduction to the algebraic approach to Markov
process duality, as opposed to the pathwise approach. In the algebraic approach, a Markov …

We show that quantum dynamics of Bose-Einstein condensates in the weakly interacting
regime can be geometrized by a Poincaré disk. Each point on such a disk represents a …

In spite of their potential usefulness, Wigner functions for systems with SU (1, 1) symmetry
have not been explored thus far. We address this problem from a physically-motivated …

We investigate two special classes of two-mode Gaussian states of light that are important
from both the experimental and theoretical points of view: the mode-mixed thermal states …

Despite its indisputable merits, the Wigner phase-space formulation has not been widely
explored for systems with SU (1, 1) symmetry, as a simple operational definition of the …

Motivated by recent advances in quantum dynamics, we investigate the dynamics of the
system with SU (1, 1) symmetry. Instead of performing the time-ordered integral for the …

We report electromagnetic field modes solving the inhomogeneous Maxwell equations for
parabolic gradient index fibers in the low refractive index contrast approximation. The first …
