Exact boson mapping of the reduced BCS pairing Hamiltonian
Feng Pan, J. P. Draayer
An exact boson mapping of the reduced BCS (equal strength) pairing Hamiltonian is considered. In the mapping, fermion pair operators are mapped exactly to the corresponding bosons.…

First order quantum phase transitions in the XX spin chain
Feng Pan, Nan Ma, Xin Guan +1
Quantum phase transitional behavior of a finite periodic XX spin-1/2 chain with nearest neighbor interaction in a uniform transverse field is studied based on the simple exact solu…
