Chiral Bound States in the Continuum

AbstractWe have studied the structure and dynamics of open discrete quantum systems, such as cold atoms in optical lattices, photons in photonic crystals, or electrons in semiconductor hetero-structures. We have identified a class of states (lattice scars) at the band center of bipartite lattices-such as the square or honeycomb lattices-which are resilient to local dissipative processes [1]. When such bipartite lattice systems are coupled to leads, lattice scarred states may remain bound within the system even when the energy-band center is embedded in the continuum spectrum of lead states-they become bound states in the continuum (BICs) [2,3]. We have shown how these states can have a dramatic impact on the transport properties through the system, enabling one to design the system-lead coupling so as to block all transmission in an energy range around the band center, introduce a Fano antiresonance, or a broad transmission peak, cf. Fig. 1 and Ref. [3]. Intriguing open questions remain as to the transport at energies where lattice symmetries imply a large density of states (van Hove singularities) [4].
