We study macroscopic aspects of crystal surface relaxation in 2+1 dimensions by accounting for nearequilibrium kinetics of transparent steps at the nanoscale. For slowly varying step geometries, we sh...
Doppler-compensated three-photon electromagnetically induced transparency
Doppler-compensated three-photon electromagnetically transparency Atomic Physics
2012/5/31
We demonstrate Doppler-compensated bright and dark states in a resonant four-level atomic system. The spectral features are the result of electromagnetically induced transparency (EIT) and absorption ...
Controlled absorption and all-optical diode action due to collisions of self-induced transparency solitons
Controlled absorption all-optical diode action collisions of self-induced transparency solitons Optics
2012/4/20
We study inelastic collisions of counter-propagating self-induced transparency solitons in a homogeneously broadened two-level medium. The energy of the pulse can be almost totally absorbed in the med...
Birefringence induced polarization-independent and nearly all-angle transparency through a metallic film
Birefringence polarization-independent all-angle
2011/9/5
We propose an birefringence route to perfect electromagnetic (EM) wave tunneling through a metallic film which relies on homogeneous birefringent coatings with moderate and positive parameters only. E...
Electrometry near a dielectric surface using Rydberg electromagnetically induced transparency
Rydberg electromagnetically induced Electrometry
2011/9/2
Electrometry near a dielectric surface is performed using Rydberg electromagnetically induced transparency (EIT). The large polarizability of high n-state Rydberg atoms gives this method extreme sensi...
Toward a more comprehensive theory of zooplankton diel vertical migration: Integrating ultraviolet radiation and water transparency into the biotic paradigm
comprehensive theory zooplankton diel vertical migration Integrating ultraviolet radiation water transparency biotic paradigm
2014/4/4
The current prevailing theory of diel vertical migration (DVM) of zooplankton is focused largely on two biotic drivers: food and predation. Yet recent evidence suggests that abiotic drivers such as da...

2010/11/25
The present paper examines the possibility of asymmetric effect of the adjacent to barrier physically different media, or anisotropic structure of the barrier itself, on probability of the oppositely ...
Observation of atomic localization using Electromagnetically Induced Transparency
atomic localization Electromagnetically Induced Transparency
2010/11/16
We present a proof-of-principle experiment in which the population of an atomic level is spatially localized using the technique of electromagnetically-induced transparency (EIT). The key idea is to ...
Measurements of vector magnetic field using multiple electromagnetically induced transparency resonances in Rb vapor

2010/11/12
We study intensity distribution of transmission resonances under the conditions of electromagnetically induced transparency (EIT) with lin||lin configuration in 87Rb vapor. We demonstrate that for va...
Electromagnetically Induced Transparency from Two Phonon Processes in Quadratically Coupled Membranes
Electromagnetically Phonon Processes Quadratically Coupled Membranes
2010/10/29
We describe how electromagnetically induced transparency can arise in quadratically coupled optomechanical systems. Due to quadratic coupling the underlying optical process involves a two phonon proce...
Multidecadal climate oscillations detected in a transparency record from a subtropical Florida lake
Multidecadal climate oscillations transparency record subtropical Florida lake
2014/4/17
Synchronous interannual variability in water transparency observed in neighboring lakes has been linked to regional precipitation and resultant runoff of dissolved organic material, but many climate f...
Variability of sporadic E-layer semi transparency (foEs-fbEs)with magnitude and distance from earthquake epicenters to vertical sounding stations
sporadic E-layer semi transparency earthquake epicenters vertical sounding stations
2009/12/11
Variations of the Es-layer semi transparency co-efficient were analyzed for more than 100 earthquakes with magnitudes M > 4 and depths h < 100 km. Data of mid latitude vertical sounding stations (Koku...
Ocean Acidification and the Increasing Transparency of the Ocean to Low-Frequency Sound
Ocean acid boric acid to dissolve carbonate ions sound waves Marine mammals
2015/7/6
As the ocean becomes more acidic, low-frequency (~ 1–3 kHz and below) sound travels much farther due to changes in the amounts of pH-dependent species such as dissolved borate and carbonate ions, whic...
