Hierarchy of localized many-body bound states in an interacting open lattice
Yanxia Liu, Shu Chen
We unveil the mechanism for the formation of puzzled boundary-localized bound states in a spinless fermionic open lattice with nearest-neighbor interactions. By solving the Bethe-a…

Fate of Two-Particle Bound States in the Continuum in non-Hermitian Systems
Yanxia Liu, Shu Chen
We unveil the existence of two-particle bound state in the continuum (BIC) in a one-dimensional interacting nonreciprocal lattice with a generalized boundary condition. By applying…
