Here, we study the characteristic feature of conventional (ON-OFF keying) and soliton based transmission system. We consider 20Gbps transmission system implemented with Conventional Single Mode Fiber (C-SMF) to examine the role of Gaussian pulse which is the characteristic of conventional propagation and Hyperbolic-secant pulse which is the characteristic of soliton propagation in it. We note t...

In a typical solitonic distribution, the soliton density is distributed over the entire moleculeand the present work shows how its density can be decomposed into solitonic and antisolitoniccomponents. It is found that there exists a unique electron as soliton over the anionicnanoconductor, while there are many other solitons and antisolitons. The solitonic states are furtherdecomposed to the ca...

Precise positioning of magnetic solitons requires controllable artificial pinning, while the accurate determination pinning profile remains a challenge. Here, we propose topological solution to this problem. Taking domain wall (DW) as representative example, study collective dynamics interacting DWs in racetrack with sites alternate distances. By mapping governing equations DW motion Su-Schrief...

For n+1 ≥ 3, we construct complete solutions to Ricci flow on R which encounter global singularities at a finite time T . The singularities are forming arbitrarily slowly with the curvature blowing up arbitrarily fast at the rate (T − t)−2λ for λ ≥ 1. Near the origin, blow-ups of such a solution converge uniformly to the Bryant soliton. Near spatial infinity, blow-ups of such a solution converg...

We estimate the mass and the width of pentaquark Θ∗ states in the {27} baryon multiplet from chiral soliton model. The calculations show that the mass of Θ∗ is about 1.60 GeV and the width for the process Θ∗ → KN is less than 44 MeV. We also discuss the search for the existence of Θ∗ states in physical processes.

The discovery of the Θ baryon [1] has led to renewed interest in the chiral soliton model for baryons. The connection between the chiral soliton and quark models is clear if they are studied as a function of the number of colors and flavors. In this paper, we derive the states obtained by collective coordinate quantization of the chiral soliton model [2], for an arbitrary number of colors Nc an...

The flavor asymmetry of the sea quark distribution as well as the unexpectedly small quark spin fraction of the nucleon are two outstanding discoveries recently made in the physics of deep-inelastic structure functions. We evaluate here the corresponding quark distribution functions within the framework of the chiral quark soliton model, which is an effective quark model of baryons maximally in...

The chiral soliton model including π, ρ, ω mesons is extended for the case when the scalar isoscalar σ meson has an anomalous dimension d. The form factor of the sigma nucleon interaction calculated and to be found not highly sensitive to the value of d. E-mail: [email protected] 1

The stability of physical systems depends on the existence of a state of least energy, or ground state. In gravity, this is guaranteed by the positive energy theorem. The proof employs spinor structure and can fail for certain spacetime topologies, such as those arising in non-supersymmetric Kaluza-Klein compactifications, which can decay to arbitrarily negative energy. The proof also fails for...

In a previous article, it has been proved under the framework of chiral soliton model that the same Isgur{Wise form factor describes the semileptonic b ! c and () b ! () c decays in the large N c limit. It is shown here that this result is in fact independent of the chiral soliton model and is solely the consequence of the spin-avor SU(4) symmetry which arises in the baryon sector in the large ...
