Two particle correlations: a probe of the LHC QCD medium 。
Researchers in the US are the first to use single fluorescent dye molecules to probe the local electromagnetic fields inside nanoscale "hotspots" on metal surfaces. The imaging technique can identify ...
On A Cosmological Invariant as an Observational Probe in the Early Universe
Cosmological Invariant Observational Probe
2011/1/11
k-essence scalar field models are usually taken to have lagrangians of the form ${\mathcal L}=-V(\phi)F(X)$ with $F$ some general function of $X=\nabla_{\mu}\phi\nabla^{\mu}\phi$. Under certain condit...
Three Roads to Probe-Brane Superconductivity
Probe-Brane Superconductivity High Energy Physics
2010/12/24
We study a defect system of two parallel D5 probe branes in a large-N_c D3 background. Using the non-abelian DBI action, we study three different fields that can give rise to a superconducting phase t...

Today reactor neutrino experiments are at the cutting edge of fundamental research in particle physics. Understanding the neutrino is far from complete, but thanks to the impressive progress in this f...
A Japanese spacecraft has successfully returned what are the first samples ever obtained from the surface of an asteroid. Using microscopic methods to study the grains, researchers have confirmed that...
Quantitative magnetic force microscopy on permalloy dots using an iron filled carbon nanotube probe
Magnetic Force Microscopy tip-induced magnetization iron lled carbon nanotube
2010/11/17
We have characterized a new Magnetic Force Microscopy (MFM) probe based on an iron lled
carbon nanotube (FeCNT) using MFM imaging on permalloy (Py) disks saturated in a high magnetic
eld perpendic...
We study a defect system of two parallel D5 probe branes in a large-Nc D3 background. Using the non-abelian DBI action, we study three dierent elds that can give rise to a superconducting phase tran...
Big Bang Nucleosynthesis as a Probe of New Physics
Big bang nucleosynthesis early Universe abundances of light elements ex-tensions of the Standard Model dark matter
2010/11/16
Big bang nucleosynthesis (BBN), an epoch of primordial nuclear transforma-tions in the expanding Universe, has left an observable imprint in the abundances of light elements. Precision observations of...
The power spectrum of the residual rotation curve velocity as a probe of past mergers
Galaxy Astrophysics (astro-ph.GA)
2010/12/27
According to the $\Lambda CDM$ cosmological framework, galaxies underwent multiple mergers in their history. In this paper we propose to use the power spectrum of the residual fluctuations of the rota...
Combining cluster observables and stacked weak lensing to probe dark energy: Self-calibration of systematic uncertainties
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We develop a new method of combining cluster observables (number counts and cluster-cluster correlation functions) and stacked weak lensing signals of background galaxy shapes, both of which are avail...
Quantum metrology to probe atomic parity nonconservation
Quantum metrology probe atomic parity nonconservation
2010/10/29
An entangled state prepared in a decoherence free sub-space together with a Ramsey type measurement can probe parity violation in heavy alkali ions like Ba+ or Ra+. Here we propose an experiment with ...
Derivation of quantum master equation with counting fields by monitoring a probe
Derivation quantum master equation counting fields monitoring a probe
2010/10/21
We show a microscopic derivation of a quantum master equation with counting terms which
describes the electron statistics. A localized spin behaves as a probe whose precession angle monitors the net ...
A signature of the dark energy equation of state may be observed in the shape of voids. We estimate the constraints on cosmological parameters that would be determined from the ellipticity distributio...
