Ultrafast Néel vector switching

Eddie Ivor Harris-Lee, John Kay Dewhurst, Wenhan Chen +3

We predict ultrafast switching in a chiral anti-ferromagnet that occurs at femtosecond times, nearly 5 orders of magnitude faster than the torque induced nanosecond switching previ…

Coupled femto-excitons, free carriers and light

Deepika Gill, Sam Shallcross, Wenhan Chen +2

Non-equilibrium quantum matter generated by ultrafast laser light opens new pathways in fundamental condensed matter physics, as well as offering rich control possibilities in "tai…

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…

Giant moment increase by ultrafast laser light

Sangeeta Sharma, Deepika Gill, Jyoti Krishna +3

It is now well established that a few femtosecond laser pulse will induce an ultrafast loss of moment in a magnetic material. Here we show that the opposite effect can also occur:…

Magnetizing altermagnets by ultrafast asymmetric spin dynamics

Zhaobo Zhou, Sangeeta Sharma, John Kay Dewhurst +1

Laser pulses are known to induce symmetric demagnetization: equal loss of magnetic moments in the identical sublattices of antiferromagnets and ferromagnets at ultrashort timescale…

Ultrafast all-optical generation of pure spin and valley currents

Deepika Gill, Sangeeta Sharma, Sam Shallcross

Pure currents comprise the flow of a two state quantum freedom -- for example the electron spin -- in the absence of charge flow. Radically different from the charge currents that…
