Dynamical Chaos in a Dissipative Driven Quantum Soft Impact Oscillator
Titir Mukherjee, Arnab Acharya, Soumitro Banerjee +1
Dynamical chaos in a periodically driven, dissipative soft impact oscillator is investigated in the quantum regime using the complex-number quantum Langevin equation (c-number QLE)…
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…
Interaction-induced wavefunction collapse
Arnab Acharya, Pratik Jeware, Soumitro Banerjee
Almost a century after the development of quantum mechanics, we still do not have a consensus on the process of collapse of wavefunctions. Some theories require the intervention of…
Limiting distribution of periodic position measurements of a quantum harmonic oscillator
Arnab Acharya, Debapriya Pal, Soumitro Banerjee +1
We consider a particle in harmonic oscillator potential, whose position is periodically measured with an instrument of finite precision. We show that the distribution of the measur…
