Non-Bloch band theory of non-Hermitian Hamiltonians in the symplectic class

29 May 2020 Kawabata Kohei Okuma Nobuyuki Sato Masatoshi

Non-Hermitian Hamiltonians are generally sensitive to boundary conditions, and their spectra and wave functions under open boundary conditions are not necessarily predicted by the Bloch band theory for periodic boundary conditions. To elucidate such a non-Bloch feature, recent works have developed a non-Bloch band theory that works even under arbitrary boundary conditions... (read more)
