Spectral Discontinuities in Constrained Dynamical Models
Sudipta Das, Subir Ghosh
As examples of models having interesting constraint structures, we derive a quantum mechanical model from the spatial freezing of a well known relativistic field theory - the chira…

Classical oscillator with position-dependent mass in a complex domain
Subir Ghosh, Sujoy Kumar Modak
We study complexified Harmonic Oscillator with a position-dependent mass, termed as Complex Exotic Oscillator (CEO). The complexification induces a gauge invariance [19,11]. The ro…
