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…
Few-Photon Fluorescence from Ultracold Bosons in an Optical Cavity
Megha Gopalakrishna, Emil Viñas Boström, Claudio Verdozzi
Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second-harmonic generation (SHG) regimes. Two settings ar…
Time resolved optical response of the Dicke's model via the nonequilibrium Green's function approach
Megha Gopalakrishna, Yaroslav Pavlyukh, Claudio Verdozzi
Due to their conceptual appeal and computational convenience, two-level systems (TLS) and their generalisations are often used to investigate nonlinear behavior in quantum optics,…
Microscopic theory of current-induced skyrmion transport and its application in disordered spin textures
Emil Östberg, Emil Viñas Boström, Claudio Verdozzi
Magnetic skyrmions hold great promise for realizing compact and stable memory devices that can be manipulated at very low energy costs via electronic current densities. In this wor…
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…
