Quantum Brownian Motion: Drude and Ohmic Baths as Continuum Limits of the Rubin Model
Avijit Das, Abhishek Dhar, Ion Santra +2
The motion of a free quantum particle in a thermal environment is usually described by the quantum Langevin equation, where the effect of the bath is encoded through a dissipative…

Non-equilibrium Quantum Langevin dynamics of orbital diamagnetic moment
Urbashi Satpathi, Supurna Sinha
We investigate the time dependent orbital diamagnetic moment of a charged particle in a magnetic field in a viscous medium via the Quantum Langevin Equation. We study how the inter…

Transmitting a signal in negative time
P. Singha Deo, Urbashi Satpathi
There is no self adjoint time operator defined in quantum mechanics. However, time intervals can be defined in several ways and can also be probed experimentally. Our interest in t…
