Bardeen-Cooper-Schrieffer state representation and pairing detection in the fermionic Tonks-Girardeau gas
We demonstrate that the ground state of the fermionic Tonks-Girardeau gas is a number-conserving Bardeen-Cooper-Schrieffer (BCS) state. This offers a compelling new perspective on describing the ground-state wave function of the fermionic Tonks-Girardeau gas, enabling a complete description in secon...
