- Title: Degeneracy and coherent states of the two-dimensional Morse potential
- Authors: James Moran
- Abstract summary: We find the dependence of the spectrum on the physical parameters and use this to understand the emergence of accidental degeneracies.
It is observed that, under certain conditions pertaining to the irrationality of the parameters, accidental degeneracies do not appear and as such degenerate energy levels are at most two-fold.

- Abstract: In this paper we construct coherent states for the two-dimensional Morse
potential. We find the dependence of the spectrum on the physical parameters
and use this to understand the emergence of accidental degeneracies. It is
observed that, under certain conditions pertaining to the irrationality of the
parameters, accidental degeneracies do not appear and as such energy levels are
at most two-fold degenerate. After defining a non-degenerate spectrum and set
of states for the 2D Morse potential, we construct generalised coherent states
and discuss the spatial distribution of their probability densities and their
uncertainty relations.

We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities.
metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating.
We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

Coexistence of Localized and Extended States [0.0]
We provide an example of a nearest-neighbor tight-binding disordered model which carries both localized and extended states without forming the mobility edge (ME)
We map the above model to the 1D Anderson model with matrix-size- and position-dependent hopping and confirm the coexistence of localized and extended states.
In addition, the mapping shows that the extended states are non-ergodic and allows to analytically estimate their fractal dimensions.

We study the topological point defects and textures of order parameters in two-dimensional quantum many-body systems.
In the absence of intrinsic topological orders, we show a connection between the symmetry properties of point defects and textures to deconfined quantum criticality.
When the symmetry-breaking ground state have intrinsic topological orders, we show that the point defects can permute different anyons when braided around.
