Entanglement Spectrum and Entanglement Thermodynamics of Quantum Hall Bilayers at nu=1 [PDF]

, 2011
We study the entanglement spectra of bilayer quantum Hall systems at total filling factor nu=1. In the interlayer-coherent phase at layer separations smaller than a critical value, the entanglement spectra show a striking similarity to the energy spectra

The Precision of Half-value Layer Measurement on Mammography

Japanese Journal of Radiological Technology, 2011
The half-value layer (HVL) is an important index of the image quality or radiation risk in mammography. Radiation risk of the breast tissue is evaluated with the average glandular dose. The HVL index is indispensable for the average glandular dose computations.
