Nonequilibrium dynamics of the Jaynes-Cummings dimer
G. Vivek, Debabrata Mondal, S. Sinha
We investigate the nonequilibrium dynamics of a Josephson-coupled Jaynes-Cummings dimer in the presence of Kerr nonlinearity, which can be realized in the cavity and circuit quantu…
Chaos and quantum scars in a coupled top model
Debabrata Mondal, Sudip Sinha, S. Sinha
We consider a coupled top model describing two interacting large spins, which is studied semiclassically as well as quantum mechanically. This model exhibits variety of interesting…
Chaos and quantum scars in Bose-Josephson junction coupled to a bosonic mode
Sudip Sinha, S. Sinha
We consider a model describing Bose-Josephson junction (BJJ) coupled to a single bosonic mode exhibiting quantum phase transition (QPT). Onset of chaos above QPT is observed from s…
Strong quantum violation of the gravitational weak equivalence principle by a non-Gaussian wave-packet
P. Chowdhury, D. Home, A. S. Majumdar +3
The weak equivalence principle of gravity is examined at the quantum level in two ways. First, the position detection probabilities of particles described by a non-Gaussian wave-pa…
Dark energy from quantum wave function collapse of dark matter
A. S. Majumdar, D. Home, S. Sinha
Dynamical wave function collapse models entail the continuous liberation of a specified rate of energy arising from the interaction of a fluctuating scalar field with the matter wa…
