Exciton-induced magnons carrying orbital angular momentum in CrI3
Martin Pavelka, Vishal Shokeen, Ruslan Chulkov +15
Magnons are collective spin excitations that contain and transport spin angular momentum in magnetic materials. It has been suggested that they can also carry orbital angular momen…
Non-equilibrium THz-phonon spin coupling in CrI3
V Shokeen, M Pavelka, R Chulkov +8
Manipulating magnetism at the THz timescale in atomically thin ferromagnets by exploiting the interactions of spins with optical phonon modes presents an innovative idea for THz sp…
Ultrafast manipulation of the NiO antiferromagnetic order via sub-gap optical excitation
Xiaocui Wang, Robin Y. Engel, Igor Vaskivskyi +19
Wide-band-gap insulators such as NiO offer the exciting prospect of coherently manipulating electronic correlations with strong optical fields. Contrary to metals where rapid depha…
XUV Spectral Compression by Four-Wave Mixing
L. Drescher, V. Shokeen, T. Witting +3
Extreme-ultraviolet (XUV) sources including high-harmonic generation, free-electron lasers, soft x-ray lasers and laser-driven plasmas are widely used for applications ranging from…
Role of Spin Flips versus Spin Transport in Non Thermal Electrons Excited by Ultrashort Optical Pulses in Transition Metals
V. Shokeen, M. Sanchez Piaia, J. -Y. Bigot +5
A joint theoretical and experimental investigation is performed to understand the underlying physics of laser-induced demagnetization in Ni and Co films. Experimentally dynamics of…
