Measurement of the branching ratios of the decays Xi0 --> Sigma+ e- nubar and anti-Xi0 --> anti-Sigma+ e+ nu
I Collaboration
From 56 days of data taking in 2002, the NA48/1 experiment observed 6316 Xi0 --> Sigma+ e- nubar candidates (with the subsequent Sigma+ --> p pi0 decay) and 555 anti-Xi0 --> anti-S…
Nonlinear entanglement witnesses, covariance matrices and the geometry of separable states
Otfried Gühne, Norbert Lütkenhaus
Entanglement witnesses provide a standard tool for the analysis of entanglement in experiments. We investigate possible nonlinear entanglement witnesses from several perspectives.…
Dissipative dynamics of atomic Hubbard models coupled to a phonon bath: Dark state cooling of atoms within a Bloch band of an optical lattice
A. Griessner, A. J. Daley, S. R. Clark +2
We analyse a laser assisted sympathetic cooling scheme for atoms within the lowest Bloch band of an optical lattice. This scheme borrows ideas from sub-recoil laser cooling, implem…
High fidelity transfer of an arbitrary quantum state between harmonic oscillators
K. Jahne, B. Yurke, U. Gavish
It is shown that by switching a specific time-dependent interaction between a harmonic oscillator and a transmission line (a waveguide, an optical fiber, etc.) the quantum state of…
Covariance matrices and the separability problem
O. Gühne, P. Hyllus, O. Gittsovich +1
We propose a unifying approach to the separability problem using covariance matrices of locally measurable observables. From a practical point of view, our approach leads to strong…
Chiral properties of the constituent quark model
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of \bar QQ state…
