Semiclassical interpretation of the spin interference effect observed in square loop arrays of In0.53Ga0.47As/In0.52Al0.48As quantum wells
(American Physical Society, 2011-12)
We present a semiclassical interpretation of the time-reversal spin interference (SI) observed in the square loop arrays made of In0.53Ga0.47As quantum wells [T. Koga et al., Phys. Rev. B 74, 041302 (2006)]. The simulated ...
Phenomenology of aging in the Kardar-Parisi-Zhang equation
(American Physical Society, 2012-03-27)
We study aging during surface growth processes described by the one-dimensional Kardar-Parisi-Zhang equation. Starting from a flat initial state, the systems undergo simple aging in both correlators and linear responses, ...
Crossover of interfacial dynamics
(American Physical Society, 1987-09)
Some dynamical models in which there is a significant interplay between interfacial and bulk degrees of freedom are treated at the mean-field (or Van Hove) level from a coarse-grained microscopic viewpoint. Specifically, ...
Position and length operators in a theory with minimal length
(AIP Publishing, 2007-05)
Relations between the notions of fundamental and minimal lengths, and duality, in a system with minimal length uncertainty relations are examined. Self-adjoint versions of operators relevant to the problem, and their ...
On the Levinson theorem for Dirac operators
(AIP Publishing, 1990-01)
For the Dirac equation with potential V(r) obeying ∫∞ 0(1+r)‖V(r)‖d r<∞ we prove a relativistic version of Levinson’s theorem that relates the number of bound states in the spectral gap [−m,m] to the variation of an ...
A comparison of viscoelastic stress wakes for two-dimensional and three-dimensional Newtonian drop deformations in a viscoelastic matrix under shear
(American Institute of Physics, 2009-07)
A recent experimental study of a Newtonian drop suspended in a viscoelastic matrix undergoing simple shear displays a transient overshoot in drop deformation which is qualitatively similar to two-dimensional (2D) numerical ...
Effect of multiple scattering on transition radiation from a dynamic interface
(American Physical Society, 1991-09)
The effect of multiple scattering (long-range, small-angle elastic Coulomb collisions) on the radiation field associated with transition radiation from a nonstationary plasmalike medium is addressed with the help of a ...
Origin of scintillation in cerium_doped oxide crystals
(AIP Publishing, 1995-05)
We propose here a model of the scintillation from complex oxide single crystalsdoped with Ce3+ ions to explain the correlation observed between scintillation light yield and intrinsic luminescence of the matrix.
Center for Soft Matter and Biological Physics Symposium Scientific Program 2019
(Virginia Tech. Center for Soft Matter and Biological Physics, 2019-05-22)
A program from the symposium held on May 22, 2019, in Hahn Hall North Atrium.
Ultraviolet and X-ray Variability of the Seyfert 1.5 Galaxy Markarian 817
(IOP PUBLISHING LTD, 2011-02)
We present an investigation of the ultraviolet and X-ray spectra of the Seyfert 1.5 galaxy Markarian 817. The ultraviolet analysis includes two recent observations taken with the Cosmic Origins Spectrograph (COS) in 2009 ...
