Ultrafast laser-driven topological phase patterning
Jianyu Wu, Arthur Niedermayr, Gaolong Cao +2
Microscopic and dynamic control over quantum states is essential for bridging fundamental studies of material properties to device function. Realizing such control at combined high…
How to Measure and Model Light-Induced Spin Transfer
Sinéad A. Ryan, Mohamed F. Elhanoty, Anya Grafov +13
Femtosecond laser light can transfer spin angular momentum between magnetic subspecies that exhibit hybridized valence bands within an alloy or compound, and represents the fastest…
How quantum selection rules influence the magneto-optical effects of driven, ultrafast magnetization dynamics
Mohamed F. Elhanoty, Olle Eriksson, Chin Shen Ong +1
Ultrafast magnetization dynamics driven by ultrashort pump lasers is typically explained by changes in electronic populations and scattering pathways of excited conduction electron…
Heat and Work in Quantum Thermodynamics: a Cybernetic Approach
William Rupush, Oscar Grånäs
We present a new proposal for distinguishing heat from work based on a control-theoretic observability decomposition. We derive a Hermitian operator representing instantaneous diss…
Photo-induced modification and relaxation dynamics of Weyl-semimetals
Jakub Šebesta, Oscar Grånäs
The use of ultrashort laser pulses to investigate the response of materials on femtosecond time-scales enables detailed tracking of charge, spin and lattice degrees of freedom. Whe…
Extended Lagrangian Born-Oppenheimer Molecular Dynamics with DFT+U
Yu Zhang, Marc J. Cawkwell, Christian F. A. Negre +2
Extended Lagrangian Born-Oppenheimer molecular dynamics (XL-BOMD) [Phys. Rev. Lett. vol. 100, 123004 (2008)] is combined with Kohn-Sham density functional theory (DFT) using a DFT+…
Photo-induced Hidden Phase of 1T-TaS2 with Tunable Lifetime
Pierre-Adrien Mante, Chin Shen Ong, Daniel Finkelstein Shapiro +3
Phase transitions are ubiquitous, appearing at every length scale from atoms to galaxies. In condensed matter, ultrafast laser pulses drive materials to highly non-equilibrium cond…
