Non real energies for Hermitian problems
Eigenvalues may not be always real for generalized eigenvalue problems even if the Hamiltonian and overlap mat […]

Multiple quantum scars and dynamics
A flat band system with interaction that possesses a single “quantum scar”, which we have proposed […]

One more topological phase with chiral edge states
Bulk-edge correspondence is universal. We do find a novel playground of the chiral edge states protected by bu […]
