Tunable optical Aharonov-Bohm effect in a semiconductor quantum ring [PDF]

, 2011
By applying an electric field perpendicular to a semiconductor quantum ring we show that it is possible to modify the single particle wave function between quantum dot (QD)-like to ring-like.

The Deformation Response of Hydrological Loading Due To Water Level Changes in Qinghai Lake

Water Resources Research
Over the past 18 years, the water level of Qinghai Lake has risen by more than 4 m, resulting in a total mass increase of approximately 22 Gt. This increase may have impacted the surface deformation and fault activity within a 100 km radius of the lake ...

Solid behavior of anisotropic rigid frictionless bead assemblies [PDF]

, 2008
We investigate the structure and mechanical behavior of assemblies of frictionless, nearly rigid equal-sized beads, in the quasistatic limit, by numerical simulation.

Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

Advanced Functional Materials, EarlyView.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.
