Aharonov–Bohm Effect for Cooper Pairs in Kerr Spacetime: Gravitomagnetic Phase Shifts From Frame Dragging

Annalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The unification of quantum mechanics and general relativity remains a central problem in fundamental physics. Here, we study the gravitomagnetic Aharonov–Bohm (AB) effect for Cooper pairs in Kerr spacetime. Frame‐dragging by a rotating black hole (BH) generates an effective vector potential through the off‐diagonal metric term gtϕ$g_{t\phi }$,

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

InfoMat, Volume 8, Issue 5, May 2026.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Patch near-field acoustical holography in cylindrical geometry

The Journal of the Acoustical Society of America, 2005
Spatial discrete Fourier transform-based near-field acoustical holography is known to suffer from windowing effects since the measurement aperture is necessarily finite. The latter effect can be mitigated by using patch holography, in which the measured field is extended beyond the measurement aperture based on successive smoothing operations.
