Non-LTE effects in supernova envelopes.
(1980)
The Sobolev method has been applied to the solution of the satistical rate equations for multi-level representations of singly ionized silicon and neutral hydrogen for various models of supernova envelopes. The physical ...
Radio-frequency emissions from runaway electron avalanche models compared with intense, transient radio-frequency signals associated with thunderstorms.
(2002)
The results of a one-dimensional model of a runaway electron avalanche, initiated by a high-energy cosmic ray secondary electron, in a thunderstorm electric field are presented. The time-evolution of the electron densities, ...
A study of the polarization interaction with application to low-energy electron-H collisions.
(1982)
The need for an understanding of the polarization interaction is discussed, and a procedure for calculating the electron-H(, 2) polarization potential based on a molecular structure code formulation of the problem is ...
Determining the distance of SN 1987A with SEAM.
(2001)
Supernovae count among the most luminous phenomena in the universe, and as such they have been sought after to serve as cosmological distance indicators. Type Ia supernovae are currently the most commonly used indicators. ...
Toward Measuring a Charge-Parity Violating Electric Dipole Moment of the Electron: Production and Pseudo-Continuous Resonance Enhanced Multiphoton Ionization of
(2009)
Over one half century has passed since the possible violation of time reversal symmetry was proposed by Purcell and Ramsey. The Standard Model predicts that a value of the e-EDM |de,SM|<10-38e · cm that is beyond ...
Time-Dependent Quantum Reactive Scattering in Hyperspherical Coordinates
(2013)
We present a time-dependent hyperspherical, wave packet method for calculating three atom state-to-state S-matrix elements.
Quantum Hall ferromagnetism in indium antimonide quantum wells.
(2005)
Antimony-based III-V semiconductors are getting increasing attention for device applications and fundamental research thanks to advances made in their growth and understanding of their properties. InSb with its extremely ...
Quantum Effects in Nodal-line Semimetals
(2020)
Topological materials such as Dirac and Weyl semimetals have relativistic quasiparticles at a discrete number of points in the Brillouin zone. Those materials are semimetalas in the bulk but host metallic surface states ...
Experimental Studies of Cesium Rydberg Atom Pair Interactions
(2009)
This thesis describes experimental studies of Rydberg atom pair interactions. A new technique is described that combines trapping of ultracold Cesium atoms with Rydberg tagging time-of-flight spectroscopy to attain a ...
