Controlling the polarization dynamics by strong THz fields in photoexcited germanium quantum wells

open access: yesNew Journal of Physics, 2013
The interaction of strong single-cycle THz pulses with the optically induced polarization in germanium quantum wells is studied. With increasing THz field strength, it is observed that the excitonic resonances shift toward higher energy and broaden ...

Split Domination Decomposition of Path Graphs

open access: yesRatio Mathematica, 2022
A decomposition (G1, G2, G3, …, Gn) of G is said to be a split domination decomposition (SDD), if the following conditions are satisfied:(i) each Gi is connected(ii), 1. In this paper, we prove that path, path corona and subdivision of path graph admit SDD.

Beating-free quantum oscillations in two-dimensional electron gases with strong spin-orbit and Zeeman interactions

open access: yesPhysical Review Research, 2023
Shubnikov-de Haas (SdH) oscillations are the fingerprint of the Landau and Zeeman splitting level structure on the resistivity in presence of a moderate magnetic field before full quantization is manifest in the integer quantum Hall effect.

DOMINATION, FIBRATIONS, AND SPLITTING

open access: yesThe Journal of Symbolic Logic
Abstract This article is concerned with finite rank stability theory, and more precisely two classical ways to decompose a type using minimal types. The first is its domination equivalence to a Morley product of minimal types, and the second is its semi-minimal analysis, both of which are useful in applications.

Lyapunov exponents for families of rotated linear cocycles

open access: yes, 2015
In this work, we are interested in the study of the upper Lyapunov exponent $\lambda^+(\theta)$ associated to the periodic family of cocycles defined by $$A_\theta(x):=A(x)R_\theta,\qquad x\in X,$$ where $A\::\: X\to \mathbb{GL}^+(2,\mathbb{R})$ is a ...

DOMINATED SPLITTING WITH STABLY EXPANSIVE [PDF]

open access: yesThe Pure and Applied Mathematics, 2011
In this paper, we show that if a transitive set is -stably expansive, then admits a dominated splitting.

C2-Stably Limit Shadowing Diffeomorphisms

open access: yesAbstract and Applied Analysis, 2015
Let f be a diffeomorphism on a C∞ closed surface. In this paper, we show that if f has the C2-stably limit shadowing property, then we have the following: (i) f satisfies the Kupka-Smale condition; (ii) if P(f) is dense in the nonwandering set Ω(f) and ...

Parton densities and structure functions at next-to-next-to-leading order and beyond [PDF]

open access: yes, 2001
We summarize recent results on the evolution of unpolarized parton densities and deep-inelastic structure functions in massless perturbative QCD. Due to last year's extension of the integer-moment calculations of the three-loop splitting functions, the ...

Deep sea megafaunal assemblages off the northern Iberian slope related to environmental factors

open access: yesScientia Marina, 2011
Four deep sea fish and invertebrate assemblages from the northern Spanish slope were identified and related to geographic and bathymetric factors. The Peñas Cape comprises a boundary area splitting the more productive, wider and sandy western shelf from ...

Computed Tomography Observation and Image-Based Simulation of Fracture Propagation in Compressed Coal

open access: yesEnergies, 2022
In this study, the fracture propagation characteristics and associated mechanisms of coal are investigated by using computed tomography (CT) observation and image-based simulation.
