All-atomic generation and noise-quadrature filtering of squeezed vacuum in hot Rb vapor

, 2012
With our all-atomic squeezing and filtering setup, we demonstrate control over the noise amplitudes and manipulation of the frequency-dependent squeezing angle of a squeezed vacuum quantum state by passing it through an atomic medium with ...

EIT and diffusion of atomic coherence

, 2005
We study experimentally the effect of diffusion of Rb atoms on Electromagnetically Induced Transparency (EIT) in a buffer gas vapor cell. In particular, we find that diffusion of atomic coherence in-and-out of the laser beam plays a crucial role in ...

Electromagnetically induced transparency in an atom-molecule Bose-Einstein condensate

, 2006
We propose a new measurement scheme for the atom-molecule dark state by using electromagnetically induced transparency (EIT) technique. Based on a density-matrix formalism, we calculate the absorption coefficient numerically.

The dependence of the EIT wave velocity on the magnetic field strength

, 2010
"EIT waves" are a wavelike phenomenon propagating in the corona, which were initially observed in the extreme ultraviolet (EUV) wavelength by the EUV Imaging Telescope (EIT). Their nature is still elusive, with the debate between fast-mode wave model and

Demonstration of double EIT using coupled harmonic oscillators and RLC circuits

, 2011
Single and double electromagnetically induced transparency (EIT) in a medium, consisting of four-level atoms in the inverted-Y configuration, are discussed using mechanical and electrical analogies.

Design and Characterisation of an EIT Current Supply Module

Current Directions in Biomedical Engineering
Electrical Impedance Tomography is used to image the cross-sectional conductivity of an object. It is clinically used for high-frame-rate imaging of lung ventilation. Most current systems use very limited current injection wave-forms and patterns.

Eit skilt som prøver å vera eit skilt

Nordic Journal of Art and Research, 2020
I kunst- og forskingsprosjektet Samarbeid mellom små og store vesen samarbeida ei gruppe born og ein kunstnar om å skapa eit kunstverk. Intensjonen med prosjektet var å utforska om likeverd og horisontalitet i kunstproduksjon beståande av asymmetriske relasjonar er mogleg.
