Short-time $\beta$-relaxation in glass-forming liquids is cooperative in nature

, 2015
Temporal relaxation of density fluctuations in supercooled liquids near the glass transition occurs in multiple steps. The short-time $\beta$-relaxation is generally attributed to spatially local processes involving the rattling motion of a particle in ...

Electronic Spin Transport in Dual-Gated Bilayer Graphene

, 2016
The elimination of extrinsic sources of spin relaxation is key in realizing the exceptional intrinsic spin transport performance of graphene. Towards this, we study charge and spin transport in bilayer graphene-based spin valve devices fabricated in a ...

Spin relaxation and decoherence of holes in quantum dots

, 2005
We investigate heavy-hole spin relaxation and decoherence in quantum dots in perpendicular magnetic fields. We show that at low temperatures the spin decoherence time is two times longer than the spin relaxation time.

Quantum-Classical Reentrant Relaxation Crossover in Dy2Ti2O7 Spin-Ice [PDF]

, 2003
We have studied spin relaxation in the spin ice compound Dy2Ti2O7 through measurements of the a.c. magnetic susceptibility. While the characteristic spin relaxation time is thermally activated at high temperatures, it becomes almost temperature ...
