The findings of a new study by University of Iowa theoretical physicist Michael Flatte could play a role in the development of future generations of smaller, more energy-efficient computers and e...
Landau damping of spin waves in trapped Boltzmann gases
Ultracold gas boltzmann spatial dependence
2014/12/20
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time evolutio...
Spin waves in the $(\pi,0)$ magnetically ordered iron chalcogenide Fe$_{1.05}$Te
Spin waves
2010/11/22
We use inelastic neutron scattering to show that the spin waves in the iron chalcogenide Fe1.05Te display novel dispersion clearly different from those in the related iron pnictide systems. By fitting...
Spin waves in magnetic quantum wells with Coulomb interaction and $sd$ exchange coupling

We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...

Entanglement of a 795 nm light polarization qubit and an atomic Rb spin wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell’s inequality (S = 2.65±0.12). Long qubit s...
Physicists in Japan have for the first time been able to transmit an electrical signal over a distance of one millimetre through an insulator using spin waves. The technique, which involves converting...
