Bright Coherent Ultrahigh Harmonics in the keV X-Ray Regime from Mid-Infrared Femtosecond Lasers

Tenio Popmintchev, Ming-Chang Chen, Dimitar Popmintchev +17

High harmonic generation traditionally combines ~100 near-infrared laser photons, to generate bright, phase matched, extreme ultraviolet beams when the emission from many atoms add…

Material Properties for the Interiors of Massive Giant Planets and Brown Dwarfs

Andreas Becker, Mandy Bethkenhagen, Clemens Kellermann +2

We present thermodynamic material and transport properties for the extreme conditions prevalent in the interiors of massive giant planets and brown dwarfs. They are obtained from e…

Central frequency of few-cycle laser pulses in strong-field processes

Joel Venzke, Tennesse Joyce, Zetong Xue +2

We analyze the role of the difference between the central frequencies of the spectral distributions of the vector potential and the electric field of a short laser pulse. The frequ…

Ab initio equations of state for hydrogen (H-REOS.3) and helium (He-REOS.3) and their implications for the interior of Brown Dwarfs

Andreas Becker, Winfried Lorenzen, Jonathan J. Fortney +3

We present new equations of state (EOS) for hydrogen and helium covering a wide range of temperatures from 60 K to 10 K and densities from g/cm to g/cm$^3…

Generation of Bright Isolated Attosecond Soft X-Ray Pulses Driven by Multi-Cycle Mid-Infrared Lasers

M. -C. Chen, C. Hernández-García, C. Mancuso +11

High harmonic generation driven by femtosecond lasers makes it possible to capture the fastest dynamics in molecules and materials. However, to date the shortest attosecond (as) pu…

Theoretical analysis of time delays and streaking effects in XUV photoionization

Jing Su, Hongcheng Ni, Andreas Becker +1

We apply a recently proposed theoretical concept and numerical approach to obtain time delays in extreme ultraviolet (XUV) photoionization of an electron in a short- or long-range…
