Measurement of the CMS Magnetic Field

, 2011
The measurement of the magnetic field in the tracking volume inside the superconducting coil of the Compact Muon Solenoid (CMS) detector under construction at CERN is done with a fieldmapper designed and produced at Fermilab.

Direct high-precision measurement of the magnetic moment of the proton

, 2014
The spin-magnetic moment of the proton $\mu_p$ is a fundamental property of this particle. So far $\mu_p$ has only been measured indirectly, analysing the spectrum of an atomic hydrogen maser in a magnetic field. Here, we report the direct high-precision

Magnetometry with entangled atomic samples

, 2004
We present a theory for the estimation of a scalar or a vector magnetic field by its influence on an ensemble of trapped spin polarized atoms. The atoms interact off-resonantly with a continuous laser field, and the measurement of the polarization ...

Measurement of the Cotton Mouton effect of water vapour

, 2013
In this paper we report on a measurement of the Cotton Mouton effect of water vapour. Measurement performed at room temperature ($T=301$ K) with a wavelength of 1064 nm gave the value $\Delta n_u = (6.67 \pm 0.45) \cdot 10^{-15}$ for the unit magnetic ...

Thermal entanglement in a two-spin-qutrit system under a nonuniform external magnetic field

, 2005
The thermal entanglement in a two-spin-qutrit system with two spins coupled by exchange interaction under a magnetic field in an arbitrary direction is investigated. Negativity, the measurement of entanglement, is calculated.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Alleviating optical pumping inhomogeneity using a polarization-encoded metasurface in NMR co-magnetometers

Microsystems & Nanoengineering
In nuclear magnetic resonance (NMR) co-magnetometers, the non-uniform transverse energy distribution of the pumping Gaussian beam can result in substantial optical pumping inhomogeneity and decoherence of atomic spins, which hinder the improvement of the
