Prospects for Studies of the Free Fall and Gravitational Quantum States of Antimatter

Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
Different experiments are ongoing to measure the effect of gravity on cold neutral antimatter atoms such as positronium, muonium, and antihydrogen. Among those, the project GBAR at CERN aims to measure precisely the gravitational fall of ultracold antihydrogen atoms.

Metaoptics with Nonrelativistic Matter Waves

Advances in OptoElectronics, Volume 2012, Issue 1, 2012., 2012
The counterpart of metamaterials in light optics for nonrelativistic matter waves governed by the Schrödinger equation can be found by transiently reversing the group velocity using a so called comoving potential. Possible applications to wave‐packet dynamics, atom interferometry, and atom deceleration are described.

Reprogrammable Mechanical Metamaterials via Passive and Active Magnetic Interactions

Advanced Materials, Volume 37, Issue 24, June 19, 2025.
The combination of flexible matrices with embedded hard‐magnetic nodes enables metastructures with reprogrammable mechanical properties, even in the absence of external magnetic fields. The evolving interaction between nodes during structural deformation allows mechanical tunability under quasi‐static and dynamic loading, and bistable transitions. This

Millimeter‐ and Submillimeter‐wave Kinetic Spectroscopy of Reaction Intermediates

Laser Chemistry, Volume 7, Issue 2-4, Page 61-77, 1987., 1987
A spectroscopic method has been developed to study chemical reaction processes through in situ observation of the time profile of molecular absorptions in the millimeter‐ and submillimeter‐wave regions. The method has been applied to oxidation reactions of unsaturated hydrocarbons initiated by mercury photosensitization.

Acceleration and Deceleration Behavior of Skyrmion Controlled by Curvature Gradient in Elliptical‐Ring Track

Advanced Electronic Materials, Volume 10, Issue 10, October 2024.
The curvature gradient of the elliptical‐ring track causes both an increase and a decrease change modes of the skyrmion's velocity. The two change modes in velocity can be used to construct skyrmion‐based devices. The increased velocity is employed to facilitate the transmission of skyrmions, while the decreased velocity is used to intercept skyrmions ...
