Carbon nanotubes and graphene are low-dimensional allotropes of carbon which exhibit novel mechanical and electrical properties. The methods for producing these materials and fabricating electronic devices from them are ...

The presence of strong interactions in quantum many-body systems makes the analytical treatment of such systems very difficult. In this thesis we explore two possible proposals for simulating strongly correlated, quantum ...

A field emitter serves as a cold source of electrons. It has practical applications in various fields such as field emission flat panel displays, multiple electron-beam lithography, ion propulsion/micro-thrusters, radio ...

This thesis aims at better understanding of the tokamak pedestal, which is a defining feature of the so-called "High Confinement Mode" or "H Mode" of tokamak operation. This region is characterized by a drastic plasma ...

The HETE satellite became operational on the 2nd of February, 2001. In the first 2.5 years of the mission prior to July 1 of 2003, 42 Gamma-ray bursts (GRBs) were promptly localized and publicized over the GRB Coordinates ...

Astronomical and cosmological evidence suggests that 27% of the energy content of the universe is in the form of non-baryonic matter referred to as "dark matter." Weakly interacting massive particles have long been considered ...
