Spin-orbit torque-mediated spin-wave excitation as an alternative paradigm for femtomagnetism
G. P. Zhang, M. Murakami, Y. H. Bai +2
Laser-induced femtosecond demagnetization, femtomagnetism, offers a potential route to develop faster magnetic storage devices. It is generally believed that the traditional spin-w…
On Dynamical Gaskets Generated by Rational Maps, Kleinian Groups, and Schwarz Reflections
Russell Lodge, Mikhail Lyubich, Sergei Merenkov +1
According to the Circle Packing Theorem, any triangulation of the Riemann sphere can be realized as a nerve of a circle packing. Reflections in the dual circles generate a Kleinian…
Ultrafast demagnetization dynamics in Ni: role of electron correlations
Shree Ram Acharya, Volodymyr Turkowski, Guo-ping Zhang Talat S. Rahman
Experimental observations of the ultrafast (less than 50 fs) demagnetization of Ni have so far defied theoretical explanations particularly since its spin-flipping time is much les…
A -chromatic two-distance graph in the plane
Geoffrey Exoo, Dan Ismailescu
We prove that if one colors each point of the Euclidean plane with one of five colors, then there exist two points of the same color that are either distance or distance ap…
All-optical spin switching under different spin configurations
G. P. Zhang, Mitsuko Murakami
We employ an atomic spin model and present a systematic investigation from a single spin to a large system of over a million spins. To have an efficient spin switching, the electro…
Magic high-order harmonics from a quasi-one-dimensional hexagonal solid
G. P. Zhang, Y. H. Bai
High-order harmonic generation (HHG) from atoms is a coherent light source that opens up attosecond physics, but it is the application of HHG to solids that brings much of exciteme…
