Accretion flows and neutron star heating in low-mass X-ray binaries
(Massachusetts Institute of Technology, 2017)X-ray binaries are excellent test beds for studies of high-energy accretion flows and the properties of compact objects. Neutron star (NS) low-mass X-ray binaries (LMXBs) vary in brightness by almost 8 orders of magnitude ... -
The accretion process in neutron-star low-mass X-ray binaries
(Massachusetts Institute of Technology, 2009)There had been long-standing fundamental problems in the spectral studies of accreting neutron stars (NSs) in low-mass X-ray binaries involving the X-ray spectral decomposition, the relations between subtypes (mainly atoll ... -
Accuracy and precision in collider event shapes
(Massachusetts Institute of Technology, 2016)In order to gain a deeper understanding of the Standard Model of particle physics and test its limitations, it is necessary to carry out accurate calculations to compare with experimental results. Event shapes provide a ... -
Acoustics in moving media

An action principle for dissipative fluid dynamics
(Massachusetts Institute of Technology, 2016)Fluid dynamics is the universal theory of low-energy excitations around equilibrium states, governing the physics of long-lived modes associated with conserved charges. Historically, fluid dynamics has been formulated at ... -
Active materials in photonic crystals
(Massachusetts Institute of Technology, 2007)I analyze new phenomena arising from embedding active materials inside of photonic crystal structures. These structures strongly modify the photonic local density of states (LDOS), leading to quantitative and qualitative ... -
Active wavefront correction in laser interferometric gravitational wave detectors
(Massachusetts Institute of Technology, 2003)As the first generation of laser interferometric gravitational wave detectors near operation, research and development has begun on increasing the instrument's sensitivity while utilizing existing infrastructure. In the ... -
Advancing the search for dark matter : from CDMS II to SuperCDMS
(Massachusetts Institute of Technology, 2012)An overwhelming proportion of the universe (83% by mass) is composed of particles we know next to nothing about. Detecting these dark matter particles directly, through hypothesized weak-force-mediated recoils with nuclear ... -
The algebraic spin liquid of a possible model description for the normal state of underdoped high temperature superconductors
(Massachusetts Institute of Technology, 2002)16 years and counting ... In 1986 Bednorz and Muller discovered the layered perovskite structure (La - Ba)2Cu04 which showed the phenomenon of superconductivity at the unprecedented high temperature of Tc = 33 K. In the ... -
