Atom-field interaction in optical resonators
(Massachusetts Institute of Technology, 1997)
Aqueous systems from first-principles : structure, dynamics and electron-transfer reactions
(Massachusetts Institute of Technology, 2006)
In this thesis, we show for the first time how it is possible to calculated fully from first-principles the diabatic free-energy surfaces of electron-transfer reactions. The excitation energy corresponding to the transfer ...
New perspectives on ab initio calculation and physical insights gained through linkage to continuum theories
(Massachusetts Institute of Technology, 2000)
We explore the use of ab initio, density-functional methods for the study of large-scale materials problems. Three examples are presented: (i) the interplay of surface and edge reconstructions in long silicon nanowires, ...
Defects, thermal phenomena and design in photonic crystal systems
(Massachusetts Institute of Technology, 2006)
The physics of blackbodies has been an ongoing source of fascination and scientific research for over a hundred years. Kirchhoff's law states that emissivity and absorptivity are equal for an object in thermal equilibrium. ...
A kinetic approach for the estimation of intracellular concentrations of nitrosative species in cells challenged by nitric oxide
(Massachusetts Institute of Technology, 2013)
Nonlinear terahertz spectroscopy of electronic and vibrational responses in condensed matter systems
(Massachusetts Institute of Technology, 2012)
In this work, I describe experiments utilizing high-field terahertz (THz) pulses to initiate nonlinear responses in several classes of materials. We have developed several methods for interrogating the nonlinear THz response ...
THz polaritonics : optical THz generation, detection, and control on a chip
(Massachusetts Institute of Technology, 2012)
The THz polaritonics system is an on-chip platform for THz generation, detection, and control. THz-frequency electromagnetic waves are generated directly in a thin slab of lithium niobate crystal where they can be amplified ...
Private regimes and legitimacy : the politics of self-regulation in liner shipping and international standardization
(Massachusetts Institute of Technology, 1998)
Promoter directionality is controlled by U1 snRNP and polyadenylation signals in mouse embryonic stem cells
(Massachusetts Institute of Technology, 2013)
RNA polymerase II (RNAPII) transcription is a tightly regulated process controlling cell type and state. Advancements in our understanding of how transcription is regulated will provide insight into the mechanisms controlling ...
D-branes and string field theory
(Massachusetts Institute of Technology, 2006)
In this thesis we study the D-brane physics in the context of Witten's cubic string field theory. We compute first few terms the low energy effective action for the non-abelian gauge field A, from Witten's action. We show ...
