Exact Quasiprobability Hierarchy of the Double-Morse Oscillator: From Potential Geometry to Operator Ordering
F. Chogle, B. Teklu, M. F. Pereira
Phase-space and quasiprobability methods play key roles across quantum technologies, characterizing localization, non-Gaussianity, nonclassical resources, and coarse-graining. We p…

Nonlinearity and Quantum Metrology in the Double-Morse Potential
Firoz Chogle, Berihu Teklu, Jorge Zubelli +1
We address the nonlinear properties of the double-Morse potential as a resource for single-mode quantum states due to its double-well structure and anharmonicity. We obtain analyti…

Spectral Analysis of a Quantum Waveguide with Elliptical Window
H. Najar, F. Chogle
We investigate the Dirichlet Laplacian in two spatial waveguides coupled through an elliptic window. The elliptic geometry breaks rotational symmetry and introduces anisotropy thro…
