New refrigerator super-cools molecules nano-Kelvin temperatures
2020/4/17
For years, scientists have looked for ways to cool molecules to ultracold temperatures, at which point the molecules should slow to a crawl, allowing scientists to precisely control their quantum beha...

UChicago scientists fireworks atoms ultra-low temperatures
2017/11/23
Scientists aren’t normally treated to fireworks when they discover something about the universe. But a team of University of Chicago researchers found a show waiting for them at the atomic level—along...

2012/4/19
Predicting the transition temperature, Tc, of a superconductor from Periodic Table normal state properties is regarded as one of the grand challenges of superconductivity. By studying the correlations...
We investigate medium effects on mesonic screening lengths for QCD with 2-flavours of dynamical staggered quarks on lattices with cutoff a=1/6T. Denoting the cross-over temperature by $T_c$, we vary t...

2010/11/19
The Heusler compounds Mn2TiZ (Z = Al, Ga, In, Si, Ge, Sn, P, As,Sb) are of large interest due to their potential ferrimagnetic properties and high spin polarization. Here, we present calculations of t...

Disentanglement and Decoherence without dissipation at non-zero temperatures
Disentanglement Decoherence without dissipation non-zero temperatures
2010/10/20
Decoherence is well understood, in contrast to disentanglement. According to common lore, irre-
versible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show...
