Persistence of nonlocality for bipartite quantum spin systems (2008-09)
Theoretical Physics Group

Advisor: Dr. Sibasish Ghosh
(Click here for the arXiv link)- Quantum theory of angular momentum (May-Jun 2008)
Theoretical Physics GroupInstitute of Mathematical Sciences, Chennai
Advisor: Dr. R.Simon
Abstract
The Schwinger's model of Angular Momentum is used to derive the Wigner-d matrix which is then used to solve for the eigenstates of a particular Hamiltonian.
- Quantum lattice solitons (May-Jul 2007)
Theoretical Physics GroupIndira Gandhi Centre for Atomic Research, Kalpakkam
Advisor: Dr. S.Sivakumar
Abstract
The Quantum Discrete Non-Linear Schrodinger lattice model, the Qauntum Ablowitz Ladik lattice model and the Salerno lattice model are discussed. This is followed by a modified Hamiltonian that interpolates between the first two models in a way different from the third, and it's solution.
- Simulation of a polymer molecule in a dilute solution: A self avoiding random walk (Jan-May 2007)
Birla Institute of Technology & Science, Pilani
Advisor: Dr. P.K.Thiruvikraman
Abstract
An empirical law relating the length of a self avoiding random walk to the number of units in it is verified and further, the dynamics of a polymer molecule in a dilute solution, modeled as a self avoiding random walk, is simulated.
- Small angle x-ray scattering (May-Jul 2006)
Material Science Division
Indira Gandhi Centre for Atomic Research, Kalpakkam
Advisor: Dr. H.K.Sahu
Abstract
The Small Angle X-ray scattering technique is used to characterize the inter-micellar distances and aggregation numbers of Sodium & Cesium Dodecyl Sulphate samples.
- A study of fast frequency fluctuations in lasers (Jun-Jul 2005)
Atomic & Optical Physics Laboratory
Indian Institute of Science, Bangalore
Advisor: Dr. Vasanth Natrajan
Abstract
An attempt is made to characterize the fast-frequency fluctuations of a
Titanium Saffire laser source by measuring the fluctuations in the
frequency of beats generated by 2 correlated beams
of the same laser- one frequency shifted slightly from the other, using a Acoustic Optic Modulator. It is assumed that one of the beams be ideal and fluctuation free while
all fluctuations arise from the other.
