Spontaneously generated atomic entanglement in free space: reinforced by incoherent pumping (2009)
Zhou, Ling, Yang, Guo Hui, Patnaik, Anil K.
We study spontaneously generated entanglement (SGE) between two identical multilevel atoms in free space via vacuum-induced radiative coupling. We show that the SGE in two-atom systems may initially...
Measurement of ground-state decoherence via interruption of coherent population trapping (2007)
Patnaik, Anil K., Hsu, Paul S., Agarwal, Girish S., Welch, George W., Scully, Marlan O.
Multiorder coherent Raman scattering of a quantum probe field (2003)
Kien, Fam Le, Patnaik, Anil K., Hakuta, K.
We study the multiorder coherent Raman scattering of a quantum probe field in a far-off-resonance medium with a prepared coherence. Under the conditions of negligible dispersion and limited...
Slow Light Propagation in a Thin Optical Fiber via Electromagnetically Induced Transparency (2002)
Patnaik, Anil K., Liang, J. Q., Hakuta, K.
We propose a novel configuration that utilizes electromagnetically induced transparency (EIT) to tailor a fiber mode propagating inside a thin optical fiber and coherently control its dispersion...
Coherent Control of Magneto-optical Rotation in Inhomogeneously Broadened Medium (2001)
Patnaik, Anil K., Agarwal, G. S.
We extend our earlier investigations [Opt. Commun. {\bf 179}, 97 (2000)] on the enhancement of magneto-optical rotation (MOR) to include inhomogeneous broadening. We introduce a control field that...
Vacuum Induced Coherences in Radiatively Coupled Multilevel Systems (2000)
Agarwal, G. S., Patnaik, Anil K.
We show that radiative coupling between two multilevel atoms having near-degenerate states can produce new interference effects in spontaneous emission. We explicitly demonstrate this possibility by...

Patnaik, Anil K., Agarwal, G. S.
The paper has been withdrawn by authors.
Controlling Magneto-Optical Rotation via Atomic COherences (1999)
Patnaik, Anil K., Agarwal, G. S.
An isotropic medium, having magnetic sublevels, when subjected to a magnetic field or an electromagnetic field can induce anisotropy in the medium; and as a result the plane of polarization of the...
Laser Field Induced Birefringence and Enhancement of Magneto-optical Rotation (1999)
Patnaik, Anil K., Agarwal, G. S.
An initially isotropic medium, when subjected to either a magnetic field or a coherent field, can induce anisotropy in the medium and can cause the polarization of a probe field to rotate. Therefore...
Cavity-induced coherence effects in spontaneous emission from pre-Selection of polarization (1998)
Patnaik, Anil K., Agarwal, G. S.
Spontaneous emission can create coherences in a multilevel atom having close lying levels, subject to the condition that the atomic dipole matrix elements are non-orthogonal. This condition is rarely...
