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…
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…
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…
Transfer Matrix description of heterostructured spintronics Terahertz emission
Yingshu Yang, Stefano Dal Forno, Marco Battiato
In this work we developed an extension to the Transfer Matrix method (TMM) to include a current source term, with the aim of describing both the transmission and emission of THz pu…
Origin of the Background Absorption in Carbon Nanotubes: Phonon-Assisted Excitonic Continuum
Stefano Dal Forno, Natsumi Komatsu, Michael Wais +8
Excitonic effects in 1D semiconductors can be qualitatively different from those in higher dimensions. In particular, the Sommerfeld factor, the ratio of the above-band-edge excito…
Comparing scattering rates from Boltzmann and dynamical mean-field theory
M. Wais, J. Kaufmann, M. Battiato +1
We compute scattering rates for electrons in the two-dimensional Hubbard model for a one-orbital metal and a two-orbital band insulator by means of the Boltzmann scattering equatio…
