Apollo's Voyage: A New Take on Dynamics in Rotating Frames
Ujan Chakraborty, Ananda Dasgupta
We first demonstrate how our general intuition of pseudoforces has to navigate around several pitfalls in rotating frames. And then, we proceed to develop an intuitive understandin…

Construction of propagators for divisible dynamical maps
Ujan Chakraborty, Dariusz Chruściński
Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide important generalization of Markovian semig…

Generic Contractive States and Quantum Monitoring of Free Masses and Oscillators
Priyanshi Bhasin, Ujan Chakraborty, S . M. Roy
Monitoring photon quadratures and free masses are useful tools to detect small disturbances such as gravitational waves.Here we report a large class of states for photon quadrature…
