Quantum interference and decoherence effects in novel systems
(2009-12)
In this thesis we studied quantum interference and decoherence effects in systems like atoms, ions, quantum dots and photonic waveguides. These systems are presently widely studied in different areas of quantum optics and ...
Electromagnetically induced transparency and quantum effects in optomechanical systems
(2011-12)
In this thesis, we study cooling, normal mode splitting, squeezing, entanglement, and electromagnetically induced transparency in the macroscopic optomechanical system. We show that a type I optical parametric amplifier ...
2D TEM-mode THz quasioptics
(2005-05)
Scope of Study: The purpose of this study was to develop a two-dimensional wave guiding structure incorporating quasioptical mirrors, lenses, diffractive elements, sources and detectors for ultrafast pulses of THz radiation. ...
Quantum imaging and sensing with entangled photons
(2008-07)
This dissertation contains new theoretical work on how to utilize the entangled photons produced in a parametric down conversion to improve resolution and sensitivity in quantum interferometry, magnetometry and lithography. ...
Anomaly mediated supersymmetry breaking and nonstandard neutrino oscillations
(2005-07)
Scope and Method of Study: In this thesis, we propose four different scenarios that solves the tachyonic slepton mass problem of Anomaly Mediated Supersymmetry Breaking (AMSB). We also address the question of neutrino ...
Comparison of plastics used in tissue equivalent proportional counters (TEPC) and development of a balloon borne TEPC
(2012-12)
This study investigates alternatives to A-150 tissue equivalent plastic for use in the construction of tissue equivalent gas-filled detectors for the measurement of dosimetric quantities. This study looks at four different ...
Role of cosmic rays in lightning initiation
(2014-07)
From electric field measurements, the maximum electric fields typically found within a thunderstorm are an order of magnitude too weak to initiate a lightning discharge. Relativistic electrons produced in galactic cosmic ...
Atomic force microscopy methods for the analysis of high-let tracks in CR-39 plastic nuclear track detector
(2009-07)
Scope and Method of Study: Proton- and neutron-induced target fragmentation reactions generate short-range (~1-10 µm), high-linear energy transfer (LET) heavy nuclear recoil (HNR) particles that contribute to total radiation ...
