Universality beyond the Kibble-Zurek mechanism in the condensation of coherently coupled Bose gases
Subhadeep Patra, Paolo Comaron, Arko Roy
We study the universal spatial statistics of point-like topological defects formed during the nonequilibrium condensation of a coherently coupled Bose gas using the stochastic proj…
Temperature driven false vacuum decay in coherently coupled Bose superfluids
Paniyanchatha Moolayil Sivasankar, Franco Dalfovo, Alessio Recati +1
The relaxation of a quantum field from a metastable state (false vacuum) to a stable one (true vacuum), also known as false vacuum decay, is a fundamental problem in quantum field…
Kibble-Zurek Scaling and Spatial Statistics in Quenched Binary Bose Superfluids
Subhadeep Patra, Arko Roy, Seong-Ho Shinn +2
The emergence of order from an initially uncorrelated state across a phase transition is a central problem in quantum many-body physics, particularly in multicomponent systems wher…
Finite-temperature phase diagram and collective modes of coherently coupled Bose mixtures
Sunilkumar V Rajat, Sandeep Gautam, Arko Roy
We investigate the ferromagnetic-paramagnetic phase transition in coherently (Rabi) coupled Bose-Einstein condensates at zero and finite temperatures, exploring different routes to…
Thermal amplification and melting of phases in spin-orbit-coupled spin-1 Bose-Einstein condensates
Ritu, Rajat, Arko Roy +1
We implement Hartree-Fock-Bogoliubov theory with Popov approximation for a homogeneous Raman-induced spin-orbit-coupled spin-1 Bose-Einstein condensate and investigate the effects…
Frequency-selective amplification of nonlinear response in strongly correlated bosons
Aditya Prakash, Debamalya Dutta, Arko Roy +1
We present a protocol to generate enhanced non-linear responses of incident pulses in the density wave phase within the extended Bose-Hubbard model using the concept of resonance-i…
Temperature-induced supersolidity in spin-orbit-coupled Bose gases
Rajat, Ritu, Arko Roy +1
Close to the superfluid plane-wave (PW) - supersolid stripe (ST) phase transition point of a zero temperature quasi-one-dimensional spin-orbit-coupled Bose gas, we find that an inc…
