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$g_{t\phi }$,

Photonic Mode Description of the Jaynes–Cummings Hamiltonian States

Annalen der Physik, Volume 538, Issue 8, August 2026.
This review presents the transmission response of a Jaynes–Cummings Hamiltonian as separate modes consisting of a “visible” photonic part a “hidden” electronic part. It connects further the modes to the dispersive shift in qubit readout, the quantum capacitance of semiconductor nanostructures and the effective dissipation rate of a two‐level system ...

Engineering NixCu(100‐x)@Ni Electrocatalysts on Microwave‐Reduced Ni/C for Efficient Hydrogen Evolution Reaction

ChemCatChem, Volume 18, Issue 16, 27 August 2026.
A synergistic three‐layer Ni30Cu70/Ni/M catalyst, consisting of a microwave‐reduced Ni/C base, an electrodeposited Ni interlayer, and a Ni–Cu alloy top layer, was developed for alkaline HER. The Ni30Cu70/Ni/M catalyst exhibited efficient catalytic activity and stable performance over 60 h.
