Effective p-wave interaction and topological superfluids in s-wave quantum gases [PDF]
, 2016 P-wave interaction in cold atoms may give rise to exotic topological superfluids. However, the realization of p-wave interaction in cold atom system is experimentally challenging.

Exact density-functional potentials for time-dependent quasiparticles
, 2012 We calculate the exact Kohn-Sham potential that describes, within time-dependent density-functional theory, the propagation of an electron quasiparticle wavepacket of non-zero crystal momentum added to a ground-state model semiconductor. The potential is

Evaluation of Rail Potential Based on Power Distribution in DC Traction Power Systems
Energies, 2016 Running rails used as a return conductor and ungrounded scheme have been widely adopted in DC traction power systems. Due to the longitudinal resistance of running rails and insulation resistance of rail-to-ground, there will be a potential rise between ...

Lattice QCD study of a five-quark hadronic molecule
, 2007 We compute the ground-state energies of a heavy-light K-Lambda like system as a function of the relative distance r of the hadrons. The heavy quarks, one in each hadron, are treated as static.

e-Prime: Advances in Electrical Engineering, Electronics and EnergyCustomarily, while designing the micro grid (MG) grounding the impact of close by grounding is not surmised. Due to which their grounding design becomes more flawed as it results in the fallacious computation of safety parameters, evincing the surplus ...

IET Generation, Transmission & Distribution, 2017 Grounding of power substations is to provide safety for personnel during normal and fault‐to‐ground conditions by limiting step and touch potentials, to dissipate lightning strokes and to stabilise voltage during transient conditions. One important goal of this study is to present simplified approaches for the earth surface potentials and ground ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
