Hamiltonian Tomography via Quantum Quench
Zhi Li, Liujun Zou, Timothy H. Hsieh
We show that it is possible to uniquely reconstruct a generic many-body local Hamiltonian from a single pair of initial and final states related by time evolution with the Hamilton…
Topological classification of non-Hermitian bands
Zhi Li, Roger S. K. Mong
We proposed a framework for the topological classification of non-Hermitian systems. Different from previous -theoretical approaches, our approach is a homotopy classification,…
Finite-temperature topological entanglement entropy for CSS codes
Zhi Li, Roger S. K. Mong
We consider topological entanglement entropy (TEE) at finite temperature for CSS codes, which include some ordinary topological-ordered systems such as the toric code and some frac…
Landau-Zener-Stückelberg Interferometry in -symmetric Non-Hermitian models
Xin Shen, Fudong Wang, Zhi Li +1
We systematically investigate the non-Hermitian generalisations of the Landau-Zener (LZ) transition and the Landau-Zener-Stückelberg (LZS) interferometry. The LZ transition probabi…
Local formula for the invariant of topological insulators
Zhi Li, Roger S. K. Mong
We proposed a formula for the invariant for topological insulators, which remains valid without translational invariance. Our formula is a local expression, in the sense that…
