Dynamics of Quantum Analogs of Classical Impact Oscillators
Arnab Acharya, Titir Mukherjee, Deepshikha Singh +1
This paper investigates the dynamics of quantum analogs of classical impact oscillators to explore how complex nonlinear behaviors manifest in quantum systems. While classical impa…

Decoherence of Morse Oscillator in the Presence of Dissipationless Environment
Titir Mukherjee, Arnab Acharya, Sushanta Dattagupta
The much-studied Morse oscillator (MO) is couched here in the context of an open quantum system, in which the interaction with the quantum environment, however, is taken to commute…

Lorentzian path integral in Kantowski-Sachs anisotropic cosmology
Saumya Ghosh, Arnab Acharya, Sunandan Gangopadhyay +1
Motivated by the recent development in quantum cosmology, we revisit the anisotropic Kantowski-Sachs model in the light of a Lorentzian path integral formalism. Studies so far have…
