Chemical Potential and Analytic Continuation for Non-Hermitian Lattice Fermions
Chen-Te Ma, Hui Zhang
We introduce a chemical potential for non-Hermitian lattice fermions and show that, for even flavors with degenerate masses and paired chemical potentials or , th…

Separability from Multipartite Measures
Chen-Te Ma, Ma-Ke Yuan
We show that the third-order negativity provides a necessary and sufficient criterion for full separability of tripartite pure states, and extend this to mixed states beyond bipart…

Lattice Chiral Fermion without Hermiticity
Chen-Te Ma, Hui Zhang
Our review of the lattice chiral fermion delves into some critical areas of lattice field theory. By abandoning Hermiticity, the non-Hermitian formulation circumvents the Nielsen-N…
