Dissertation title: Development of Optical Fibre Chemical Probes by Oblique Angle Deposition
The work involved the development of an optical fibre chemical sensor based on the technique of surface-enhanced Raman scattering (SERS). SERS relies on the close interaction between the target analyte molecule and a nanostructured metal surface. This nanostructure was fabricated using the method of oblique angle deposition (OAD) under thermal evaporation.
light and matter flirt
years pass in femtoseconds
a bond is broken
Weizmann Institute of Science
My dissertation is about quantum control of atoms and small molecule using intense femtosecond laser pulses. Ever since the invention of the laser, physicists and chemists have aspired to utilize its unique properties to control photochemical reactions selectively and efficiently. In the research described in my thesis I have studied and controlled various aspects of intense light matter interaction. In particular, dissociation processes of diatomic molecules, strong field coherent anti-Stokes Raman scattering (CARS) in traces of solids, and strong field two-photon absorption in atomic systems.
Ring tuned on chip by EWOD
Water filtered light
Hebrew University of Jerusalem, Israel
EWOD (pronounced E-WOD, like e-book) – electrowetting on dielectrics, an electrical method for translating and deforming the shape of droplets, is used to tune an on chip micro ring resonator (change the attenuated wavelength of this optical filter) through controlling its coverage by a droplet of water.

Lightening the big dark
Weizmann Institute of Science
My dissertation is about the microscopical physics of black holes. As part of a greater effort to use String theory methods to give a first principle derivation for thermodynamical behavior of black holes. The first part focuses on a phase transition in a class of black holes known as BTZ. The second part focuses on the emergence of entropy at zero temperature for a class of black hole know as SUSY-ADS5.

University of Washington, Seattle
Dissertation Title: “Optical Trapping of Ytterbium Atoms”
I was trying to see if ytterbium atoms can be optically trapped, and if so, determine whether a sensitive search for violation of time reversal symmetry can be carried out using the trapped ytterbium atoms. In most cases, if you took movies of interactions among elementary particles, the interaction you see by playing the movie both forward and backward would look like they follow the same set of rules, and you wouldn’t be able to tell whether the movie is playing backward or forward. We are looking for interactions that look like they don’t follow the same set of rules depending on which way you play the movie, therefore you would be able to tell which way the movie is running. It turns out, you can trap ytterbium, and they glow like fireflies, but the time reversal symmetry experiment is damn difficult.

Higher twist quanta
In hadronic wave functions --
Thomas D. Gutierrez
University of California, Davis
Dissertation Title: “Higher Twist Contributions to Charm and Light Gluino Production” (2000).
Large mass particle fluctuations in hadronic wave functions, such as intrinsic charm quarks in a proton, can fragment into very forward, or leading, particles in the final state of a collision. This work uses an intrinsic charm model to predict both the distribution of forward moving charm hadrons and exotic R-hadrons (particles containing hypothetical light gluinos) for a variety of initial state particles and energies.

The Standard Model is wrong,
What gives them their mass?
University Of Malaya
I worked on the problem of neutrinos having mass for my final year project. As it stands, the Standard Model of particle physics does not incorporate massive neutrinos (all neutrinos are considered massless), and I investigated several ways in which the Standard Model can be augmented to include these new neutrinos.
Cold, thin, plastic film
Reduce thickness by squeezing
Squeeze harder and fail
Trinity College, Dublin
Dissertation Title: Nanomechanical Forming Studies of Thin Polymer Films.
An attempt to understand the behaviour of solid thin films when compressed with very small punches. The polymer would flow nicely during the embossing leaving imprinted patterns in the film. It turns out there is a limit to how much material that can be squeezed out from under the punch depending on the size of the punch used. Pushing really really hard won’t make a difference.
