Ultrafast control of spin order by linearly polarized light in noncollinear antiferromagnetic metals
J. Kimak, M. Nerodilova, K. Carva +15
The non-thermal optical control of magnetic order offers a promising route to ultrafast, energy-efficient information technologies. Although optical manipulation of magnetism in me…
Terahertz response of confined electron-hole pair: crossover between strong and weak confinement
Filip KlimoviÄ, Filip Klimovič, Jens Paaske +2
We analyze theoretically THz response of an electron-hole pair confined in a semiconductor nanoparticle. We show that the interplay of particle confinement and electron-hole Coulom…
Sub-nanosecond heat-based logic, writing and reset in an antiferromagnetic magnetoresistive memory
M. Surynek, A. Farkas, J. Zubac +9
Thermal logic aims to create thermal counterparts to electronic circuits. In this work, we investigate experimentally the response of an analog memory device based on a thin film o…
Photon-assisted ultrafast electron-hole plasma expansion in direct band semiconductors
T. Troha, F. KlimoviÄ, T. Ostatnický +2
Time-resolved terahertz spectroscopy is used to investigate formation and ultrafast long-distance propagation of electron-hole plasma in strongly photoexcited GaAs and InP. The obs…
