Role of Spin-Orbit Coupling in High-order Harmonic Generation Revealed by Super-Cycle Rydberg Trajectories
Nicola Mayer, Samuel Beaulieu, Alvaro Jimenez-Galan +7
High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it w…
Vibrational relaxation of hot ground state cations of naphthalene
Geert Reitsma, Serguei Patchkovskii, Judith Dura +4
Time-resolved XUV-IR photoion mass spectroscopy of naphthalene conducted with broadband, as well as with wavelength-selected narrowband XUV pulses reveals a rising probability of f…
Ultrafast Proton Transport between a Hydroxy Acid and a Nitrogen Base along Solvent Bridges Governed by Hydroxide/Methoxide Transfer Mechanism
Maria Ekimova, Felix Hoffmann, Gül Bekçioğlu-Neff +4
Aqueous proton transport plays a key role in acid-base neutralization, and energy transport through biological membranes and hydrogen fuel cells. Extensive experimental and theoret…
Phase-Dependence of Resonant and Antiresonant Two-Photon Excitations
Lorenz Drescher, Tobias Witting, Oleg Kornilov +1
Measurements of the phase of two-photon matrix elements are presented for resonant and antiresonant two-color ionization of helium. A tunable, narrow-bandwidth, near-infrared (NIR)…
Phase cycling of extreme ultraviolet pulse sequences generated in rare gases
Andreas Wituschek, Oleg Kornilov, Tobias Witting +4
The development of schemes for coherent nonlinear time-domain spectroscopy in the extreme-ultraviolet regime (XUV) has so far been impeded by experimental difficulties that arise a…
Observation of autoionization dynamics and sub-cycle quantum beating in electronic molecular wave packets
M. Reduzzi, W. -C. Chu, C. Feng +9
The coherent interaction with ultrashort light pulses is a powerful strategy for monitoring and controlling the dynamics of wave packets in all states of matter. As light presents…
Extreme-ultraviolet refractive optics
Lorenz Drescher, Oleg Kornilov, Tobias Witting +6
Refraction is a well-known optical phenomenon that alters the direction of light waves propagating through matter. Microscopes, lenses and prisms based on refraction are indispensa…
Laser-induced persistent photovoltage on the surface of a ternary topological insulator at room temperature
J. Sánchez-Barriga, M. Battiato, E. Golias +4
Using time- and angle-resolved photoemission, we investigate the ultrafast response of excited electrons in the ternary topological insulator (BiSb)Te to fs-i…
Sub-picosecond spin dynamics of excited states in the topological insulator BiTe
J. Sánchez-Barriga, M. Battiato, M. Krivenkov +9
Using time-, spin- and angle-resolved photoemission, we investigate the ultrafast spin dynamics of hot electrons on the surface of the topological insulator BiTe following…
Interference stabilization of autoionizing states in molecular studied by time- and angular-resolved photoelectron spectroscopy
Martin Eckstein, Nicola Mayer, Chung-Hsin Yang +4
An autoionizing resonance in molecular N is excited by an ultrashort XUV pulse and probed by a subsequent weak IR pulse, which ionizes the contributing Rydberg states. Time- an…
Alignment and characterization of the two-stage time delay compensating XUV monochromator
Martin Eckstein, Johan Hummert, Markus Kubin +5
We present the design, implementation and alignment procedure for a two-stage time delay compensating monochromator. The setup spectrally filters the radiation of a high-order harm…
Ultrafast spin polarization control of Dirac fermions in topological insulators
J. Sánchez-Barriga, E. Golias, A. Varykhalov +7
Three-dimensional topological insulators (TIs) are characterized by spin-polarized Dirac-cone surface states that are protected from backscattering by time-reversal symmetry. Contr…
Photoemission of BiSe with Circularly Polarized Light: Probe of Spin Polarization or Means for Spin Manipulation?
J. Sánchez-Barriga, A. Varykhalov, J. Braun +12
Topological insulators are characterized by Dirac cone surface states with electron spins aligned in the surface plane and perpendicular to their momenta. Recent theoretical and ex…
Matter Wave Diffraction from an Inclined Transmission Grating: Searching for the Elusive He-4 Trimer Efimov State
R. Bruehl, A. Kalinin, O. Kornilov +3
The size of the helium trimer is determined by diffracting a beam of He-4 clusters from a 100 nm grating inclined by 21 degree. Due to the bar thickness the projected slit width is…
