Experimental Investigation of Multielectron Bubbles in Liquid Helium
(2017-11-28)Multielectron bubbles (MEBs) are micron sized cavities in liquid helium that contain electrons confined within a nanometer thick layer on the inner surface of a bubble. These objects present a rich platform to study the ... -
Experimental investigations on metal-insulator transition and structure in amorphous carbon films
Conductivity of carbon films prepared from TCPA at pyrolysis temperatures of 700°C, 800°C, and 900°C was measured by varying the temperature between 1.4 K to 300 K. To study the effect of substrates, films were deposited ... -
Experimental Studies in Quantum Optics using Diode Lasers
This thesis discusses experimental studies with vapor cells containing rubidium (Rb) or cesium (Cs) atoms. Transitions in the atoms (D1 and D2 lines) are accessed using diode lasers. Experiments are performed at room ... -
Experimental Studies Of Electron Spin Dynamics In Semiconductors Using A Novel Radio Frequency Detection Technique
(2015-08-05)A novel experimental setup has been realized to measure weak magnetic moments which can be modulated at radio frequencies (~1–5 MHz). Using an optimized radio-frequency (RF) pickup coil and lock-in amplifier, an experimental ... -
Experimental studies on n-type conduction in Bi Doped Ge-Se glasses : role of phase-separation and defects
In summary, the earlier evidence for phase separation in Ge??Se????Bi? glassy systems was discussed. Phase?separation evidence at both microscopic and macroscopic levels was also found in another Bi?doped glass system, ... -
An experimental study on thermoelectric transport at van der Waals interfaces
When two planar atomic or molecular layers are brought to sub-nanometer proximity, they form a van der Waals interface because the van der Waals force forms the dominant attractive force between them. The van der Waals ... -
Experiments on the 852 nm D2 Line of 133Cs with a Diode Laser System and their use in Measurement of the Permanent Electric Dipole Moment of the Electron
(2018-07-14)We give a brief introduction to atomic physics and the motivation behind our experiments in the first chapter. The electron’s electric dipole moment is an interesting quantity which is yet to be measured. In the 3rd Chapter, ... -
Exploration of multiferroicity, emergence of exchange bias effect and glassy magnetism in doped hexagonal rare-earth manganites
In recent days, the need for device miniaturization has led to immense research activities in the field of material science. It has become essential to discover and design new materials or to modify the existing materials ... -

Explorations in the Space of S-Matrices
S-matrix is one of the fundamental observables of the quantum theory of relativistic particles. The quantum dynamics of relativistic particles can be abstractly understood in terms of S-matrix bypassing a Lagrangian ... -
Explorations of singularities in some hydrodynamical partial differential equations
The global regularity problem for the 3D Euler equations remains unsolved. The presence of finite-time singularities (FTS) can signal the breakdown of the PDE as a physical model for fluid flow; it is also conjectured to ... -
