Modelling of Spintronic Terahertz Emitters as a function of spin generation and diffusion geometry
Yingshu Yang, Stefano Dal Forno, Marco Battiato
Spintronic THz emitters (STE) are efficient THz sources constructed using thin heavy-metal (HM) and ferromagnetic-metal (FM) layers. To improve the performance of the STE, differen…
Secondary spin current driven efficient THz spintronic emitters
Piyush Agarwal, Yingshu Yang, Rohit Medwal +4
Femtosecond laser-induced photoexcitation of ferromagnet (FM)/heavy metal (HM) heterostructures have attracted attention by emitting broadband terahertz frequencies. The phenomenon…
From rogue waves to solitons
Amdad Chowdury, Wonkeun Chang, Marco Battiato
Using a generalized nonlinear Schrödinger equation, we investigate the transformation of a fundamental rogue wave to a collection of solitons. Taking the third-order dispersion, se…
Higher-order rogue wave fission under the effects of third-order dispersion, self-steepening and self-frequency shift
Amdad Chowdury, Wonkeun Chang, Marco Battiato
Using the generalised nonlinear Schrödinger equation, we investigate how the effect of third-order dispersion, self-steepening, and Raman-induced-self-frequency shift have an impac…
Perturbative Transfer Matrix Method for optical-pump-THz-probe of ultrafast dynamics
Yingshu Yang, Stefano Dal Forno, Marco Battiato
Ultrafast optical excitations trigger in materials a range of dynamics. An interesting range of dynamics is the ones that unfold within the picosecond timescale, corresponding to t…
Spatiotemporal pattern formation in nonlinear coupled reaction-diffusion systems with a mixed-type modal discontinuous Galerkin approach
Satyvir Singh, Marco Battiato, Vinesh Kumar
The nonlinear coupled reaction-diffusion (NCRD) systems are important in the formation of spatiotemporal patterns in many scientific and engineering fields, including physical and…
