Electrically reconfigurable extended lasing state in an organic liquid-crystal microcavity

This paper demonstrates a room-temperature, electrically reconfigurable organic liquid-crystal microcavity that enables controlled in-plane coupling between spatially separated lasing states to generate a tunable, extended coherent "supermode" with precise near-field, far-field, and phase-locking engineering capabilities.

Electric-Field Control of Quantum Tunneling Regimes in Focused He-Ion-Beam-Irradiated Oxide Interfaces

This paper demonstrates that helium focused ion beam irradiation can create tunable nanoscale potential barriers at oxide interfaces, allowing a single device to transition between thermionic emission, direct tunneling, and Fowler-Nordheim tunneling regimes via electrostatic gating.

Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot

The paper reports that electron spin resonance in a planar Si-MOS quantum dot exhibits an enhanced Rabi frequency near a valley level anti-crossing due to electric-dipole transitions activated by inter-valley spin coupling, offering a potential mechanism for fast all-electrical spin control.
