Suppersymmetric strings and waves in D=3, N=2 matter coupled gauged supergravities
Deger, NS; Sarioglu, O (2004-12-01)
We construct new 1/2 supersymmetric solutions in D = 3, N = 2, matter coupled, U(1) gauged supergravities and study some of their properties. In the most general case they represent a string superposed with gravitational and Chern-Simons electromagnetic waves. The waves are attached to the string and the solution satisfied an electromagnetic self-duality relation. When the sigma model is non-compact it interpolates between as asymptotically Kaigorodov space and a naked singularity. For the compact sigma mod...

AdS-plane wave and pp-wave solutions of generic gravity theories
GÜRSES, METİN; Sisman, Tahsin Cagri; Tekin, Bayram (2014-12-02)
We construct the anti-de Sitter-plane wave solutions of generic gravity theory built on the arbitrary powers of the Riemann tensor and its derivatives in analogy with the pp-wave solutions. In constructing the wave solutions of the generic theory, we show that the most general two-tensor built from the Riemann tensor and its derivatives can be written in terms of the traceless Ricci tensor. Quadratic gravity theory plays a major role; therefore, we revisit the wave solutions in this theory. As examples of o...
Scrambling dynamics and many-body chaos in a random dipolar spin model
Keleş, Ahmet; Zhao, Erhai; Liu, W. Vincent (2019-05-01)
Is there a quantum many-body system that scrambles information as fast as a black hole? The Sachev-Ye-Kitaev model can saturate the conjectured bound for chaos, but it requires random all-to-all couplings of Majorana fermions that are hard to realize in experiments. Here we examine a quantum spin model of randomly oriented dipoles where the spin exchange is governed by dipole-dipole interactions. The model is inspired by recent experiments on dipolar spin systems of magnetic atoms, dipolar molecules, and ni...
CHAOTIC ELECTRON TRAJECTORIES IN ELECTROMAGNETIC WIGGLER FREE-ELECTRON LASER WITH A GUIDE MAGNETIC-FIELD
BILIKMEN, S; OMAR, A (Springer Science and Business Media LLC, 1994-05-01)
The Hamiltonian for an electron travelling through a large-amplitude backward electromagnetic wave, an axial guide magnetic field and radiation field is formulated. Poincare surface-of-section plots show that this Hamiltonian is non-integrable, and leads to chaotic trajectories. Equilibrium conditions are derived in the limit where the radiation field approaches zero. Compared to conventional FEL, the total energy of the system at pondermotive resonance E(c) is large, while the electron's critical energy...
