Light-wave-controlled Haldane model in monolayer hexagonal boron nitride - NatureDiscrete symmetries like spatial inversion and time reversal influence material properties. Breaking these symmetries can lead to bandgap formation and distinct carrier dynamics.
The quantum transition of the two-dimensional Ising spin glass - NatureQuantum spins on square lattice with specific coupling matrix have random, independent variables in simulations. Observables have thermal expectation values averaged over couplings.
