This paper examines the soliton phase shift using a simplified third-order generalized nonlinear Schrodinger equation (3-order GNLSE). In this investigation, we employ a new direct algebraic (NDA) technique to solve these models. All evaluated solutions are put to the test using two modern numerical (trigonometric quantic and cubic B-spline) schemes. The necessary criteria for implementing numerical systems are derived from the computational solutions. As the model captures the dynamical behavior of ultra-short pulses in optical fiber and quantum fields, this research is crucial. As a wave model, the 3-order GNLSE equation may be used to illustrate the wave nature of matter. It is regarded as a quantum-mechanical state function since it may represent the dynamical and physical behavior of atoms and transistors. The exactness of the answers is shown through two-dimensional, three-dimensional, and contour charts (matching between analytical and numerical solutions). The answers presented in the research are innovative in comparison to earlier findings.AMS classification: 35C08; 37K40; 35C07; 37K40.

This paper examines the soliton phase shift using a simplified third–order generalized nonlinear Schrödinger equation (3–order GNLSE). In this investigation, we employ a new direct algebraic (NDA) technique to solve these models. All evaluated solutions are put to the test using two modern numerical (trigono-metric quantic and cubic B–spline) schemes. The necessary criteria for implementing numerical systems are derived from the computational solutions. As the model captures the dynamical behavior of ultra–short pulses in optical fiber and quantum fields, this research is crucial. As a wave model, the 3–order GNLSE equation may be used to illustrate the wave nature of matter. It is regarded as a quantum–mechanical state function since it may represent the dynamical and physical behavior of atoms and transistors.

“…However, previous studies have focused on time-averaged changes in electronic or energy-level structures. Sub-cycle spectroscopy [19][20][21][22][23][24][25][26][27][28][29][30][31], which detects time-dependent responses within one cycle of the external field, provides detailed information on the amplitude and phase of the wavefunctions of photon-dressed states. A schematic of the photon-dressed states formed by a pump light with a frequency hΩ (period T = 2π/Ω) is shown in figure 1.…”

A periodic electric field of light applied on a solid is predicted to generate coupled states of the light electric fields and electronic system called photon-dressed Floquet states. Previous studies of those Floquet states have focused on time-averaged energy-level structures. Here, we report time-dependent responses of Floquet states of excitons generated by a mid-infrared (MIR) pulse excitation in a prototypical one-dimensional (1D) Mott insulator, a chlorine-bridged nickel-chain compound, [Ni(chxn)2Cl](NO3)2 (chxn:cyclohexanediamine). Sub-cycle reflection spectroscopy on this compound using a phase-locked MIR pump pulse and an ultrashort visible probe pulse with the temporal width of ∼7 fs revealed that large and ultrafast reflectivity changes occur along the electric field of the MIR pulse; the reflectivity change reached approximately 50% of the original value around the exciton absorption peak. It comprised a high-frequency oscillation at twice the frequency of the MIR pulse and a low-frequency component following the intensity envelope of the MIR pulse, which showed different probe-energy dependences. Simulations considering one-photon-allowed and one-photon-forbidden excitons reproduced the temporal and spectral characteristics of both the high-frequency oscillation and low-frequency component. These simulations demonstrated that all responses originated from the quantum interferences of the linear reflection process and nonlinear light-scattering processes owing to the excitonic Floquet states characteristic of 1D Mott insulators. The present results lead to the developments of Floquet engineering, and demonstrate the possibility of rapidly controlling the intensity of visible or near-IR pulse by varying the phase of MIR electric fields, which will be utilized for ultrafast optical switching devices.
