Interferometry based on quantum Kibble-Zurek mechanism
Han-Chuan Kou, Peng Li
We propose an interferometry within the framework of quantum Kibble-Zurek mechanism by exemplifying two prototypical quench protocols, namely the round-trip and quarter-turn ones,…
Ring-Frustrated Non-Hermitian Model
Shihao Bi, Yan He, Peng Li
We study a non-Hermitian version of XY closed chain with odd number of lattice sites. We consider both anti-ferromagnetic coupling and also a symmetric non-collinear spin coupling.…
Exact Solution to Sodium-Iridate-BCS-Hubbard Model along the Symmetric Line: Non-trivial topology in the ferromagnetic order
Shihao Bi, Yan He, Peng Li
We study the sodium-iridates model on the honeycomb lattice with both BCS pairing potential and Hubbard interaction term. It is shown that this model can be exactly solved with app…
Impurity-driven transitions in frustrated quantum Ising ring
Han-Chuan Kou, Zhen-Yu Zheng, Peng Li
We study the quantum phase transitions driven by a point impurity in a chain seamed with ring frustration. Rich phases and quantum phase transitions are uncovered and characterized…
Quaternary Jordan-Wigner mapping and topological extended-kink phase in the interacting Kitaev ring
Zhen-Yu Zheng, Han-Chuan Kou, Peng Li
On a ring, a single Jordan-Wigner transformation between the Kitaev model and the spin model suffers redundant degrees of freedom. However, we can establish an exact quaternary Jor…
Ring frustration and factorizable correlation functions of critical spin rings
Peng Li, Yan He
Basing on the exactly solvable prototypical model, the critical transverse Ising ring with or without ring frustration, we establish the concept of nonlocality in a many-body syste…
