In-medium similarity renormalization group for a pairing-plus-particle-hole model
L. H. Chen, Y. G. Yao, B. C. He
We benchmark two implementations of the in-medium similarity renormalization group (IMSRG) method, IMSRG(2) and IMSRG(2*), for the low-lying states of a pairing-plus-particle-hole…

Emulating generator coordinate method with extended eigenvector continuation: Lipkin-Meshkov-Glick model
Q. Y. Luo, X. Zhang, L. H. Chen +1
We present a benchmark study of generator coordinate method (GCM) combined with eigenvector continuation (EC) in two different schemes for the low-lying states of Lipkin-Meshkov-Gl…
