Superfluidity in the stochastic limit by L. Accardi, S. V. Kozyrev

“…We discuss the stochastic limit approach to superfluidity. Starting from the usual Hamiltonian describing the interaction between the Bose condensate and the normal phase, we prove the existence of superfluidity in the stochastic limit and deduce a nonlinear (quadratic) kinetic equation describing the evolution of the density of superfluid liquid.…”

(In)stability of symbiotic vortex-bright soliton in holographic immiscible binary superfluids by Yu-Ping An, Li Li

“…Abstract Symbiotic vortex-bright soliton structures with non-trivial topological charge in one component are found to be robust in immiscibel two-component superfluids, due to the effective potential created by a stable vortex in the other component. …”

Nucleonic Direct Urca Processes and Cooling of the Massive Neutron Star by Antikaon Condensations by Yan Xu, Wen Bo Ding, Cheng Zhi Liu, J. L. Han

“…Massive neutron stars turn warmer with the protonic S01 superfluids. However, the decline of the critical temperatures of the protonic S01 superfluids for the large optical potential of antikaons can speed up the cooling of the massive neutron stars.…”
