A Membrane Interferometer
bilayer lipid membrane black lipid membrane fluorescence interference contrast
2016/5/25
Freestanding phospholipid bilayers have been assembled spanning shallow, micrometer-sized wells etched into a Si wafer substrate so that the bilayers are near (within hundreds of nanometers) but not i...
Fabry–Perot interferometer as a solar background noise suppressor:application to daytime lidar
Lidar Atmosphere Daytime
2015/8/24
Continuous atmospheric probing by a lidar is a requirement for many applications. However, due to high solar background noise during the daytime, lidar operations are mostly restricted to night-time. ...

Decoherence in a Double-Dot Aharonov-Bohm Interferometer
Decoherence Double-Dot Aharonov-Bohm Interferometer
2010/11/23
Coherence in electronic interferometers is typically believed to be restored fully in the limit of small voltages, frequencies and temperatures. However, it is crucial to check this essentially pertur...
We show that the total quantum efficiency of multiple optical modes cannot increase under linear-optical processing. That is, the sum of quantum efficiencies of any K output modes of a linear-optical ...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
