SU(3) Squeezing: quantum and semiclassical perspectives
Abstract:
Squeezing is well understood for harmonic oscillator and spin
systems as resulting from ``non-classical’’ correlations between basis
states in the Hilbert space. In this talk I will introduce a definition
of squeezing for SU(3) systems, illustrate how it can be understood
geometrically as a generalization of the known definition, and contrast
some properties of squeezing obtained from a suitable initial coherent
state using the fully quantum and a semiclassical evolution generated by
a Hamiltonian non-linear in the generators of the su(3) algebra. This
is collaborative work with H. Tavakoli Dinani and A. Klimov.
