Light-wave-controlled Haldane model in monolayer hexagonal boron nitride

S. Mitra, Á. Jiménez-galán, et al.

This exciting research by Sambit Mitra, Álvaro Jiménez-Galán, and their colleagues explores optical control over time-reversal symmetry breaking in monolayer hexagonal boron nitride, achieving ultrafast switching in band structure configurations. This groundbreaking work paves the way for dynamic valley-selective bandgap engineering and few-femtosecond quantum switches.
