Dynamical Quantum Phase Transitions and Many-Body Backflow in Open Quantum Systems
Kai Zhang, Chang Shu, Kai Sun
Dynamical quantum phase transitions (DQPTs) are non-equilibrium transitions characterized by the orthogonality between an initial quantum state and its time-evolved counterpart fol…
Non-Bloch Dirac Points and Phase Diagram in the Stacked Non-Hermitian SSH Model
Megan Schoenzeit, Chang Shu, Kai Zhang +1
Topological semimetals exhibit protected band crossings in momentum space, accompanied by corresponding surface states. Non-Hermitian Hamiltonians introduce geometry-sensitive feat…
Ultra spectral sensitivity and non-local bi-impurity bound states from quasi-long-range non-hermitian skin modes
Chang Shu, Kai Zhang, Kai Sun
A fundamental tenet of quantum mechanics is that the energy spectrum of a quantum system shall remain stable against infinitesimally weak and spatially confined perturbations. In t…
Algebraic non-Hermitian skin effect and generalized Fermi surface formula in arbitrary dimensions
Kai Zhang, Chang Shu, Kai Sun
The non-Hermitian skin effect, characterized by a proliferation of exponentially localized edge modes in open-boundary systems, has led to the discovery of numerous novel physical…
