Geometric creation of quantum vorticity

Good, Michael R.R.; Xiong, Chi; Chua, Alvin J.K.; Huang, Kerson (2015)

We consider superfluidity and quantum vorticity in rotating spacetimes. The system is described by a complex scalar satisfying a nonlinear Klein-Gordon equation. Rotation terms are identified and found to lead to the ...
Relativistic superfluidity and vorticity from the nonlinear Klein-Gordon equation

Good, Michael R.R.; Xiong, Chi; Guo, Yulong; Liu, Xiaopei; Huang, Kerson (2014)

We investigate superfluidity, and the mechanism for creation of quantized vortices, in the relativistic regime.The general framework is a nonlinear Klein-Gordon equation in curved spacetime for a complex scalar field, whose ...
