Electronic Density versus Geometry for Machine-Learned Molecular Absorption Spectra

Siddharth Dhanpal, Peter Elliott, Paolo Emilio Trevisanutto +2

Molecular optical absorption spectroscopy provides a direct probe of electronic structure and is widely used for molecular identification, interpretation of photophysical behaviour…

Orbital angular momentum in crystalline solids: non-equilibrium theory

Sangeeta Sharma, Peter Elliott, Samuel Shallcross

We develop a general operator theory of orbital angular momentum (OAM) in periodic solids that applies equally to equilibrium and coherently driven states. Employing the crystal mo…

All optical ultrafast pure spin current in the altermagnet CrSO

Deepika Gill, Ruikai Wu, Peter Elliott +2

All-optical generation of pure spin current -- the flow of spin in the absence of a corresponding charge flow -- relies on a symmetry based compensation of valley charge. The 2d $d…

Valley polarization of graphene via the saddle point

Deepika Gill, Sangeeta Sharma, Peter Elliott +2

Graphene, and other members of the monolayer Xene family, represent an ideal materials platform for "valleytronics", the control of valley localized charge excitations. The absence…

Ultrafast Saddletronics

Sangeeta Sharma, Deepika Gill, John Kay Dewhurst +2

Low energy valleys in the band structure of 2d materials represent a potential route to the ultrafast writing of information in quantum matter by laser light, with excited charge a…

Where does the spin angular momentum go in laser induced demagnetisation?

J. K. Dewhurst, S. Shallcross, P. Elliott +3

The dynamics of ultrafast demagnetisation in 3 magnets is complicated by the presence of both spin and orbital angular momentum, with the microscopic mechanism…

Ultrafast demagnetization in bulk vs thin films: an ab-initio study

K. Krieger, P. Elliott, T. Müller +4

We report on {\it ab-initio} simulations of the quantum dynamics of electronic charge and spin when subjected to intense laser pulses. By performing separate calculations for a Ni…

Ultrafast Local Magnetization and Demagnetization in Heusler Alloys

P. Elliott, T. Müller, J. K. Dewhurst +2

With the goal of pushing Spintronic devices towards faster and faster timescales, we demonstrate, using ab-intio time-dependent density functional theory simulations of bulk Heusle…

Laser induced ultrafast demagnetization: an \emph{ab-initio} perspective

K. Krieger, J. K. Dewhurst, P. Elliott +2

Time-dependent density functional theory is implemented in an all electron solid-state code for the case of fully non-collinear spins. We use this to study laser induced demagnetiz…
