Quantum Magnetic Skyrmions on Kondo-type Lattices
Zhen Zhao, Emil Östberg, Ferdi Aryasetiawan +1
A quantum description is given of nanoskyrmions in 2D textures with localised spins and itinerant electrons, isolated or coupled to leads, in or out-of-equilibrium. The spin-electr…

Löwdin's symmetry dilemma within Green functions theory for the one-dimensional Hubbard model
J. -P. Joost, N. Schlünzen, S. Hese +4
The energy gap of correlated Hubbard clusters is well studied for one-dimensional systems using analytical methods and density-matrix-renormalization-group (DMRG) simulations. Beyo…

Zeno-clocking the Auger decay
Emil Viñas Boström, Mathieu Gisselbrecht, Tomas Brage +3
A tenet of time-resolved spectroscopy is -faster laser pulses for shorter timescales- . Here we suggest turning this paradigm around, and slow down the system dynamics via repeated…
