Physics of manipulation of spin dynamics in a driven double well made transparent
Results in Physics, 2022 We study the coherent manipulation of quantum spin dynamics via simple analytic solutions for a spin–orbit (SO) coupled ultracold atom held in a driven double well.

Understanding Quantum Tunneling through Quantum Monte Carlo Simulations. [PDF]
Physical Review Letters, 2015 The tunneling between the two ground states of an Ising ferromagnet is a typical example of many-body tunneling processes between two local minima, as they occur during quantum annealing.

Observation of optical tunneling inhibition by a parabolic potential in twisted photonic lattices
Physical Review Research, 2022 Quantum tunneling is considered the cornerstone of many physical processes. So far, its evolution over time, especially under an external field superimposed on the periodic potential field, has not been directly observed experimentally due to the harsh ...

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Integration of resonant band with asymmetry in ferroelectric tunnel junctions
npj Computational Materials, 2022 We propose that the asymmetry-induced tunneling electroresistance (TER) effect in a ferroelectric tunnel junction (FTJ) could be improved by integrating a polarization-controlled resonant band. Using first-principles calculations and a quantum-mechanical

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling
