Structure and scaling of Kitaev chain across a quantum critical point in real space
Yan He, Chih-Chun Chien
The spatial Kibble-Zurek mechanism (KZM) is applied to the Kitaev chain with inhomogeneous pairing interactions that vanish in half of the lattice and result in a quantum critical…
Exact Solutions of Topological Superconductor Model with Hubbard Interactions
Yiting Deng, Yan He
We study a two-dimensional model of topological superconductor with equal spin pairing and repulsive Hubbard interaction. When the pairing gap equals to the hopping constant, half…
BCS thermal vacuum of fermionic superfluids and its perturbation theory
Xu-Yang Hou, Ziwen Huang, Hao Guo +2
The thermal field theory is applied to fermionic superfluids by doubling the degrees of freedom of the BCS theory. We construct the two-mode states and the corresponding Bogoliubov…
Unified treatment of Fermi pockets and arcs scenarios for the cuprates: Sum rule consistent response functions of the pseudogap
Peter Scherpelz, Adam Rançon, Yan He +1
Essential to understanding the cuprate pseudogap phase is a study of the charge (and spin) response functions, which we address here via a consistent approach to the Fermi arcs and…
Quantum oscillations in non-Fermi liquids: Implications for high-temperature superconductors
Peter Scherpelz, Yan He, K. Levin
We address quantum oscillation experiments in high Tc superconductors and the evidence from these experiments for a pseudogap versus a Fermi liquid phase at high magnetic fields. A…
Theory of Fluctuating Charge Ordering in the Pseudogap Phase of the Cuprates Via A Preformed Pair Approach
Yan He, Peter Scherpelz, K. Levin
We study the static and dynamic behavior of charge ordering within a d-wave pair pseudogap (pg) scenario. This is addressed using a density-density correlation function derived fro…
