Real spectra in one-dimensional single-band non-Hermitian Hamiltonians
Haoyan Chen, Yi Zhang
In general, the energy spectrum of a non-Hermitian system turns out to be complex, which is not so satisfactory since the time evolution of eigenstates with complex eigenvalues is…

Fermionic Higher-form Symmetries
Yi-Nan Wang, Yi Zhang
In this paper, we explore a new type of global symmetriesthe fermionic higher-form symmetries. They are generated by topological operators with fermionic parameter, which act on…
