Observation of Intensity-Intensity Correlation Speckle Patterns with Thermal Light

open access: yes, 2014
In traditional Hanbury Brown and Twiss (HBT) schemes, the thermal intensity-intensity correlations are phase insensitive. Here we propose a modified HBT scheme with phase conjugation to demonstrate the phase-sensitive and nonfactorizable features for ...

Narrowing of EIT resonance in a Doppler Broadened Medium [PDF]

open access: yes, 2001
We derive an analytic expression for the linewidth of EIT resonance in a Doppler broadened system. It is shown here that for relatively low intensity of the driving field the EIT linewidth is proportional to the square root of intensity and is ...

The processing of infrequently-presented low-intensity stimuli during natural sleep: An event-related potential study

open access: yesNoise and Health, 2010
Event-related potentials (ERPs) provide an exquisite means to measure the extent of processing of external stimuli during the sleep period. This study examines ERPs elicited by stimuli with physical characteristics akin to environmental noise encountered
