A wealth of astrophysical evidence confirms that 26% of the energy density of the universe is comprised of a mysterious, non-baryonic, dark matter. A leading …
The dominant component of matter in the universe, referred to as dark matter, cannot be explained by the standard model of particle physics. A leading …
Fractional quantum Hall (FQH) liquids are interesting two-dimensional electron systems that possess quasiparticle excitations with fractional charges, obeying quantum statistics different from those of bosons …
In this thesis, we present two variations of the standard measurement technique used for making picosecond ultrasonic measurements. In the first variation, a resonant optical …
It has been proposed that a hidden conformal symmetry governs the dynamics of low frequency scattering in a general Kerr black hole background, enabling a …
We explore the geometrical and dynamic variations of self-assembled colloidal mono-membrane systems composed of filamentous fd virus in the presence of a polymer depletant using …
This thesis presents a measurement of the mass of the top quark. The top quarks are produced through proton-antiproton collisions with $\sqrt{s}$=1.96 TeV at the …
An electron injected into liquid helium strongly repels the surrounding helium atoms away due to the Pauli exclusion principle, and confines its own wavefunction inside …
We systematically studied the spin-dependent transport and electrical noise characteristics of MgO-based magnetic tunnel junctions (MTJs). Utilizing the coherent tunneling effect in the MgO tunnel …
Several aspects of transport in fractional quantum Hall (FQH) systems are investigated. The focus is on the FQH system at filling factor 5/2, which is …
We present an experimental study of the driven diffusion of colloids and DNA inside a micro-channel, and interstitials in two-dimensional colloid crystal. Photo-lithography and soft-lithography …
Membranes self-assembled from rod-like molecules in aqueous suspension have attracted much attention recently. Depletion force is the key factor to make the molecules self-assemble. The …
The Ludwig-Soret effect, also known as thermal diffusion, refers to the separation of mixtures in a temperature gradient. Thermal diffusion is governed by a pair …
The vortex matter in type-II superconductors continues to be a subject of great fascination in condensed matter physics. A longstanding theoretical and experimental problem is …
In condensed matter physics the vortex lattice of type-II superconductors provides a prototype for studying the effect of random pinning on elastic systems. One important …
The Universe is expanding at an ever increasing rate. The mysterious source of this acceleration has been dubbed "dark energy" and constitutes 70% of the …
The superconductor-insulator transition (SIT) is a well-known phenomenon that is observed in many types of superconducting systems, including elemental films and high Tc superconductors. Ultrathin …
We study both analytically and numerically the experimentally observed nonaxisymmetric droplet deformation and orientation in a uniform DC electric field. The theoretical model shows that …
Nanopores can be used as sensors to probe the structure of single polymers. In a typical experiment, a thin insulating membrane containing a nanometer-scale pore …
