Ultrafast room-temperature valley manipulation in silicon and diamond
Adam Gindl, Martin Ämel, FrantiÅ¡ek Trojánek +2
Some semiconductors have more than one degenerate minimum of the conduction band in their band structure. These minima-known as valleys-can be used for storing and processing infor…
High harmonic generation in monolayer MoS2 controlled by resonant and near-resonant pulses on ultrashort time scales
Pavel Peterka, Artur O. Slobodeniuk, Tomáš Novotný +5
We report on experimental investigation of nonperturbative high harmonic generation (HHG) in monolayer MoS2 in the ultraviolet spectral region driven by mid-infrared light. We stud…
Picosecond transfer from short-term to long-term memory in analog antiferromagnetic memory device
M. Surynek, J. Zubac, K. Olejnik +9
Previous experiments in compensated magnets have demonstrated a potential for approaching the limit of fastest and least-dissipative operation of digital memory bits. However, the…
Noncollinear phase-matching of high harmonic generation in solids
Pavel Peterka, František Trojánek, Petr Malý +1
We propose and experimentally demonstrate a scheme allowing to reach noncollinear phase-matching of high harmonic generation in solids, which may potentially lead to an enhancement…
