Evolution of dopant-induced helium nanoplasmas
S. R. Krishnan, Ch. Peltz, L. Fechner +13
Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump-probe experiment using few-cycle laser pulses in combination with…
Dopant induced ignition of helium nanodroplets in intense few-cycle laser pulses
S. R. Krishnan, L. Fechner, M. Kremer +13
We demonstrate ultrafast resonant energy absorption of rare-gas doped He nanodroplets from intense few-cycle (~10 fs) laser pulses. We find that less than 10 dopant atoms "ignite"…
Non-equilibrium coherence dynamics in one-dimensional Bose gases
S. Hofferberth, I. Lesanovsky, B. Fischer +2
Low-dimensional systems are beautiful examples of many-body quantum physics. For one-dimensional systems the Luttinger liquid approach provides insight into universal properties. M…
Ultracold atoms in radio-frequency-dressed potentials beyond the rotating wave approximation
S. Hofferberth, B. Fischer, T. Schumm +2
We study dressed Bose-Einstein condensates in an atom chip radio-frequency trap. We show that in this system sufficiently strong dressing can be achieved to cause the widely used r…
Radio-frequency dressed state potentials for neutral atoms
S. Hofferberth, I. Lesanovsky, B. Fischer +2
Potentials for atoms can be created by external fields acting on properties like magnetic moment, charge, polarizability, or by oscillating fields which couple internal states. The…
