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.

Velocity-selected magnetic guiding of Zeeman-decelerated hydrogen atoms [PDF]
The European Physical Journal D, 2016 An original design of magnetic guide is presented, suitable for use with Zeeman-decelerated supersonic beams of ground-state hydrogen atoms and other light paramagnetic species. Three-dimensional particle trajectory simulations show that, by combining a series of permanent-magnet Halbach arrays with pulsed high-current wire electromagnets, this guide ...

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.

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 ...

OH hyperfine ground state: from precision measurement to molecular qubits
, 2006 We perform precision microwave spectroscopy--aided by Stark deceleration--to reveal the low magnetic field behavior of OH in its ^2\Pi_{3/2} ro-vibronic ground state, identifying two field-insensitive hyperfine transitions suitable as qubits and ...

Loss of molecules in magneto-electrostatic traps due to nonadiabatic transitions
, 2008 We analyze the dynamics of a paramagnetic, dipolar molecule in a generic "magneto-electrostatic'' trap where both magnetic and electric fields may be present.

Nonadiabatic transitions in electrostatically trapped ammonia molecules [PDF]
, 2009 Nonadiabatic transitions are known to be major loss channels for atoms in magnetic traps, but have thus far not been experimentally reported upon for trapped molecules.

Continuous Centrifuge Decelerator for Polar Molecules
, 2013 Producing large samples of slow molecules from thermal-velocity ensembles is a formidable challenge. Here we employ a centrifugal force to produce a continuous molecular beam with a high flux at near-zero velocities.
