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 ...
Disorder effect in graphene and topological insulator
(2012-07)
Scope and Method of Study:
Study of secondary neutrons from uniform scanning proton beams by means of experiment and simulation
(2013-07)
Proton radiotherapy is becoming popular as an effective modality to treat cancer. However the advantages of the proton radiotherapy could be offset due to the effect of secondary neutrons. Secondary neutrons are an undesired ...
State dependence of quantum ratchets
(2017-05)
This dissertation reports on the experimental investigation of quantum state evolution using the atomic-optical quantum delta kicked rotors (AOQDKR) with a Bose- Einstein condensate (BEC) of 87Rb atoms. To achieve the ...
Cavity-enhanced evanescent-wave chemical sensing using microresonators
(2006-12)
Scope and Method of Study: The purpose of this research was to examine fused silica microresonators into which light was evanescently coupled into whispering-gallery modes (WGMs) using a tapered optical fiber. The high ...
Dynamics of kicked laser cooled rubidium atoms
(2006-07)
Scope and Method of Study: The purpose of this research was to use laser cooling techniques to cool a sample of rubidium 87 atoms and pulse the cold atoms with an off-resonant standing wave of light. Among the objectives ...
