This research advances fundamental understanding in topological quantum physics by demonstrating precise control over electron flow through non-Hermitian ladder systems with staggered hopping parameters. The ability to reverse and engineer these topological phase boundaries offers new pathways for developing robust zero-energy modes essential for future quantum information processing architectures.
Capital Normal University Maps Quantum Ladder’s Topological Phase Boundaries

Capital Normal University researchers map topological phase boundaries in a quantum ladder system with staggered nonreciprocal hopping.
Researchers at Capital Normal University have discovered a way to control the flow of electrons in a novel quantum system by manipulating its topological properties. The team, working with a “ladder” model combining standard and non-Hermitian chains, discovered they could reverse the direction of a phenomenon where electrons accumulate at the edges of a material, and even make it energy dependent through precise parameter adjustments. Zero-energy topological edge modes within this ladder system are spatially separated, residing…
