Stability of non-linear integrable accelerator
Stability of non-linear integrable accelerator Accelerator Physics
2012/5/29
The stability of non-linear Integrable Optics Test Accelerator (IOTA) model was tested. The area of the stable region in transverse coordinates and the maximum attainable tune spread were found as a f...
Non-linear magneto-optic and self polarization rotation by superposition of states
Non-linear magneto-optic self polarization rotation superposition of states Optics
2012/4/24
We report the observation of enhanced magneto-optic rotation as the coherent superposition of different hyperfine states is established in an atomic sample. The polarization rotation near the two phot...
Scaling laws for the non-linear coupling constant of a Bose-Einstein condensate at the threshold of delocalization
Scaling laws the non-linear coupling constant Bose-Einstein condensate threshold of delocalization
2012/2/28
We explore the localization of a quasi-one-, quasi-two-, and three-dimensional ultra-cold gas by a finite-range defect along the corresponding 'free'-direction/s. The time-independent non-linear Schro...
Defects in the discrete non-linear Schrodinger model
Defects non-linear Schrodinger model High Energy Physics - Theory
2011/7/27
Abstract: The discrete non-linear Schrodinger (NLS) model in the presence of an integrable defect is examined. The problem is viewed from a purely algebraic point of view, starting from the fundamenta...
Abstract: In a series of recent papers the author has introduced the notion of (regular) pseudo-bosons showing, in particular, that two number-like operators, whose spectra are ${\Bbb N}_0:={\Bbb N}\c...
Non-linear corrections to inflationary power spectrum
Non-linear corrections inflationary power spectrum
2010/12/21
We study non-linear contributions to the power spectrum of the curvature perturbation on super-horizon scales, produced during slow-roll inflation driven by a canonical single scalar field. We find th...
Non-linear QCD dynamics and exclusive production
Non-linear QCD dynamics exclusive production
2011/1/5
In this contribution we analyse the cross sections for the exclusive vector meson production as
well as the deeply virtual Compton scattering (DVCS) relying on the color dipole approach and
consider...
A Unified Theory of Non-Linear Electrodynamics and Gravity
Unified Theory Non-Linear Electrodynamics Gravity
2010/12/20
We describe a class of unified theories of electromagnetism and gravity. The Lagrangian is of the BF type, with a potential for the B-field, the gauge group is U(2) (complexified).

Arbitrary-order non-linear self-steepening
2010/11/16
Based on the recently published generalized Miller formula, we derive the spectral dependence of the contribution of arbitrary-order non-linear indices to the group-velocity index. We show that in th...

Study double non linear quantum resonances diatomic molecules
2010/11/5
We study the quantum dynamics of diatomic molecule driven by a circularly polarized resonant electric field. We look for a quantum effect due to classical chaos appearing due to the overlapping of no...

Non-linear dynamics double-cavity optical bistability three-level ladder system
2010/10/21
We present non-linear dynamical features of two-photon double-cavity optical bistability exhibited by a three level ladder system in the mean field limit. The system exhibits a hump like feature in th...
