PairDiagSph: Generalization of the Exact Pairing Diagonalization Program for Spherical Systems
Xiaoyu Liu, Chong Qi, Xin Guan +1
We present an efficient program for the exact diagonalization solution of the pairing Hamiltonian in spherical systems with rotational invariance based on the SU(2) quasi-spin alge…
Complete reduction of integrals in two-loop five-light-parton scattering amplitudes
Xin Guan, Xiao Liu, Yan-Qing Ma
We reduce all the most complicated Feynman integrals in two-loop five-light-parton scattering amplitudes to basic master integrals, while other integrals can be reduced even easier…
Shape phase transition in the odd Sm nuclei: effective order parameter and odd-even effect
Yu Zhang, Xin Guan, Yin Wang +3
Some binding-energy-related quantities serving as effective order parameters have been used to analyze the shape phase transition in the odd Sm nuclei. It is found that the signals…
The Heine-Stieltjes correspondence and the polynomial approach to the standard pairing problem
Feng Pan, Xin Guan, Mingxia Xie +2
A new approach for solving the Bethe ansatz (Gaudin-Richardson) equations of the standard pairing problem is established based on the Heine-Stieltjes correspondence. For pairs…
A progressive diagonalization scheme for the Rabi Hamiltonian
Feng Pan, Xin Guan, Yin Wang +1
A diagonalization scheme for the Rabi Hamiltonian, which describes a qubit interacting with a single-mode radiation field via a dipole interaction, is proposed. It is shown that th…
New exact solutions of the standard pairing model for well-deformed nuclei
Feng Pan, Ming-Xia Xie, Xin Guan +2
A new step-by-step diagonalization procedure for evaluating exact solutions of the nuclear deformed mean-field plus pairing interaction model is proposed via a simple Bethe ansatz…
