Real-space microscopic description of laser-pulse induced melting of superconductivity
Karl Bergson Hallberg, Guillermo Nava Antonio, Chiara Ciccarelli +1
Quenching quantum order via laser pulses has proven a useful tool to access exotic physical effects in systems that are strongly perturbed out of equilibrium. However, theoretical…
Electric and spin current vortices in altermagnets
Arsen Herasymchuk, Karl Bergson Hallberg, Erik Wegner Hodt +3
Altermagnets constitute a class of collinear magnets with momentum-dependent spin splitting and vanishing net magnetization. Direct observation of the characteristic altermagnetic…
Visualization of spin-splitter effect in altermagnets via non-equilibrium Green functions on a lattice
Karl Bergson Hallberg, Erik Wegner Hodt, Jacob Linder
When a charge current is injected into an altermagnet along a suitable crystallographic direction, a transverse spin current can be generated. This so-called spin-splitter effect d…
Orbital splitter effect and spatial resolution of current-induced orbital accumulation
Niels Henrik Aase, Erik Wegner Hodt, Karl Bergson Hallberg +2
The emergence of an orbital angular momentum (OAM) response to a charge current holds promise for technological applications, allowing electrical control of magnetization dynamics.…
