Anomalous Pairing Currents and a Second Topological Edge Channel in Bosonic Lattices
Chitrak Bhadra, Ãngel Rivas, Miguel A. Martin-Delgado
We show that bosonic pairing opens a second chiral current channel on a 2D kagome lattice, absent from any particle-conserving model. From the continuity equation, we derive both a…

Controlling the effect of quantum fluctuations in a driven nonlinear parametric oscillator
Somnath Roy, Chitrak Bhadra, Dhrubajyoti Biswas
This study investigates the interplay between a high-frequency external forcing and the intrinsic dynamics of a quantum nonlinear parametric oscillator. To analyze this system, cla…

Quantum Engines and Refrigerators
Loris Maria Cangemi, Chitrak Bhadra, Amikam Levy
Engines are systems and devices that convert one form of energy into another, typically into a more useful form that can perform work. In the classical setup, physical, chemical, a…
