Renormalization of the tunnel splitting in a rotating nanomagnet
Renormalization of the tunnel rotating nanomagnet
<

We study spin tunneling in a magnetic nanoparticle with biaxial anisotropy that is free to rotate about its anisotropy axis. Exact instanton of the coupled equations of motion is found that connects d...
Vortex Rings in Fast Rotating Bose-Einstein Condensates
Bose-Einstein Condensates Vortices Gross-Pitaevskii energy
<
2010/12/3
When Bose-Einstein condensates are rotated suciently fast, a giant vortex phase appears, that
is the condensate becomes annular with no vortices in the bulk but a macroscopic phase circulation aroun...

2010/11/23
We study ultracold bosons in a one-dimensional rotating ring lattice with a weak potential barrier well below unit filling. Due to the potential barrier the eigenstates are superpositions of different...

When our Sun was young it rotated much more rapidly than now. Observations of young, rapidly rotating stars indicate that many possess substantial magnetic activity and strong axisymmetric magnetic fi...
Charged fermions tunneling from accelerating and rotating black holes

<
2010/12/21
We study Hawking radiation of charged fermions from accelerating and rotation black holes with electric and magnetic charges. We calculate the tunneling probabilities of incoming and outgoing fermioni...

2010/12/20
In this paper, we study slowly rotating black hole solutions in Lovelock gravity (n = 3). These exact slowly rotating black hole solutions are obtained in uncharged and charged cases, respectively.
The Twente Turbulent Taylor-Couette (T3C) facility: strongly turbulent (multi-phase) flow between two independently rotating cylinders

We consider four-dimensional U(1)4 gauged supergravity, and obtain asymptotically AdS4,
non-extremal, charged, rotating black holes with one non-zero U(1) charge. The thermodynamic
quantities are co...
