Energy spectrum and quantum phase transition of the coupled single spin and an infinitely coordinated Ising chain
Beilstein J. Nanotechnol. 2025, 16, 1668–1676, doi:10.3762/bjnano.16.117
- we obtain the spectrum of the whole system and study the properties of the ground-state quantum phase transition. Keywords: Ising chain; Lipkin–Meshkov–Glick model; quantum phase transitions; Introduction In the present manuscript, we consider a single spin connected to an infinitely coordinated
