Discrete symmetries spatial inversion and time reversal impact material electronic properties, such as graphene's semimetal-like behavior vs. hexagonal boron nitride's insulating behavior when symmetry is broken.
Breaking time-reversal symmetry in graphene by a staggered magnetic field can create bandgap modifications, affecting carrier dynamics at energy-degenerate local band minima in quantum valleys.
Manipulating band structures through tailored light waveforms can induce changes in monolayer hexagonal boron nitride, showcasing the influence of symmetries on material properties.
Valley-selective excitation with circularly polarized light in gapped graphene and transition metal dichalcogenides highlights advancements in valleytronics, emphasizing the impact of symmetry manipulation on carrier dynamics.
