Low frequency flicker noise has been argued to occur in spatially extended metastable systems near a critical point (Bak et al., 1987). An Ising-Glauber model based method is suggested here to systematically obtain temperature dependent nth-order cor

Materials with no net magnetization are generally not magneto-optically active. While this is individually true for a collinear antiferromagnet (AFM) and a topological insulator (TI), it is shown here that the magneto-optic Kerr effect (MOKE) emerges

Adiabatic gate operations required to remain within the qubit subspace in an anharmonic oscillator can be slow when compared to qubit decoherence times. However, significant gate speedups are possible using methods such as derivative-removal-by-adiab

It is shown here that $1/f^\alpha$ flux noise in conventional low-T$_c$ SQUIDs is a result of low temperature superparamagnetic phase transitions in small clusters of strongly correlated color center defects. The spins in each cluster interact via lo

In the Kerr rotation geometry, magneto-optic memory devices typically suffer from low figure-of-merit (FOM) and long write times. We show that skyrmions formed at the interface of a thin-film multiferroic and a topological insulator can give rise to

Strong coupling between the electronic states of monolayer transition metal dichalcogenides (TMDCs) such as ${\mathrm{MoS}}_{2},{\mathrm{MoSe}}_{2},{\mathrm{WS}}_{2}$, or ${\mathrm{WSe}}_{2}$, and a single in-plane optical cavity mode gives rise to v

Interlayer misorientation in transition metal dichalcogenides alters their interlayer distance, total energy, electronic band structure, and vibrational modes, but its effect on the interlayer resistance is not known. This study analyzes the interlay

Interlayer electron transport through a graphene/hexagonal boron-nitride (h-BN)/graphene heterostructure is strongly affected by the misorientation angle $\ensuremath{\theta}$ of the h-BN with respect to the graphene layers with different physical me
