Phase matching in Vector Beam Driven High Harmonic Generation with 3D-printed Gas Cells
Danny Attiyah, Hunter Allison, Peter Kazansky +6
We present experimental results of high harmonic generation(HHG) driven by a 1300 nm beam in three different polarization states: linear, radial, and azimuthal. We found that the o…
Propagation of Spin Waves in Doubly Periodic Magnonic Crystals
Adam G. Whitney, Joshua M. Lewis, Justin Dickovick +3
Towards the development of strategies for tailoring spin-wave band gaps in magnonic crystals, this work examines the band gap properties in a one-dimensional magnonic crystal with…
Lévy Light Cones and Critical Causality in Fractional Multiscale Quantum Ising Models
Joshua M Lewis, Zhexuan Gong, Lincoln D Carr
We study causality and criticality in a one-dimensional fractional multiscale transverse-field Ising model, where fractional derivatives generate long range interactions beyond the…
Exploring Multiscale Quantum Media: High-Precision Efficient Numerical Solution of the Fractional Schrödinger equation, Eigenfunctions with Physical Potentials, and Fractionally-Enhanced Quantum Tunneling
Joshua M. Lewis, Lincoln D. Carr
Fractional evolution equations lack generally accessible and well-converged codes excepting anomalous diffusion. A particular equation of strong interest to the growing intersectio…
