Conformal Field Theories generated by Chern Insulators under Quantum Decoherence
Kaixiang Su, Nayan Myerson-Jain, Cenke Xu
We demonstrate that the fidelity between a pure state trivial insulator and the mixed state density matrix of a Chern insulator under decoherence can be mapped to a variety of two-…
Higher-form Symmetries under Weak Measurement
Kaixiang Su, Nayan Myerson-Jain, Chong Wang +2
We aim to address the following question: if we start with a quantum state with a spontaneously broken higher-form symmetry, what is the fate of the system under weak local quantum…
A Multicritical Point with Infinite Fractal Symmetries
Nayan Myerson-Jain, Kaixiang Su, Cenke Xu
Recently a ``Pascal's triangle model" constructed with rotor degrees of freedom was introduced, and it was shown that (.) this model possesses an infinite…
Page Curve from Non-Markovianity
Kaixiang Su, Pengfei Zhang, Hui Zhai
In this letter, we use the exactly solvable Sachdev-Ye-Kitaev model to address the issue of entropy dynamics when an interacting quantum system is coupled to a non-Markovian enviro…
Quench dynamics of entanglement spectrum and topological superconducting phases in a long-range Hamiltonian
Kaixiang Su, Zheng-Hang Sun, Heng Fan
We study the quench dynamics of entanglement spectra in the Kitaev chain with variable-range pairing quantified by power-law decay rate . Considering the post-quench Hamiltonian…
