Chaos assisted many-body tunnelling
Urbashi Satpathi, Sayak Ray, Amichay Vardi
We study the interplay of chaos and tunnelling between two weakly-coupled Bose-Josephson junctions. The classical phase space of the composite system has a mixed structure includin…
Quantum Brownian Motion of a charged oscillator in a magnetic field coupled to a heat bath through momentum variables
Suraka Bhattacharjee, Urbashi Satpathi, Supurna Sinha
We study the Quantum Brownian motion of a charged particle moving in a harmonic potential in the presence of an uniform external magnetic field and linearly coupled to an Ohmic bat…
Long Time Tails in Quantum Brownian Motion of a charged particle in a magnetic field
Suraka Bhattacharjee, Urbashi Satpathi, Supurna Sinha
We analyse the long time tails of a charged quantum Brownian particle in a harmonic potential in the presence of a magnetic field using the Quantum Langevin Equation as a starting…
