Phase Measurement of Resonant Two-Photon Ionization in Helium
M. Swoboda, T. Fordell, K. Klünder +7
We study resonant two-color two-photon ionization of Helium via the 1s3p 1P1 state. The first color is the 15th harmonic of a tunable titanium sapphire laser, while the second colo…
High-spin spectroscopy and the onset of quasicollective structures in Ga
F. E. Idoko, A. D. Ayangeakaa N. Sensharma, C. J. Chiara +30
The intermediate- and high-spin level structure of the odd- Ga nucleus was investigated via the Mg(Ca, ) fusion evaporation reaction at a beam energy…
An introduction to functions in Wiener spaces
M. Miranda, M. Novaga, D. Pallara
We present the foundations of the theory of functions of bounded variation and sets of finite perimeter in abstract Wiener spaces.
Photoionization in the time and frequency domain
M. Isinger, R. J. Squibb, D. Busto +11
Ultrafast processes in matter, such as the electron emission following light absorption, can now be studied using ultrashort light pulses of attosecond duration (s) in th…
Scale-invariant nonlinear optics in gases
C. M. Heyl, H. Coudert-Alteirac, M. Miranda +8
Nonlinear optical methods are becoming ubiquitous in many areas of modern photonics. They are, however, often limited to a certain range of input parameters, such as pulse energy a…
The dynamical state of RX J1347.5-1145 from a combined strong lensing and X-ray analysis
M. Miranda, M. Sereno, E. De Filippis +1
We perform a combined X-ray and strong lensing analysis of RX J1347.5-1145, one of the most luminous galaxy clusters at X-ray wavelengths. We show that evidence from strong lensing…
Phase measurement of a Fano window resonance using tunable attosecond pulses
M. Kotur, D. Guenot, A. Jimenez-Galan +16
We study the photoionization of argon atoms close to the 3s3p 3s3p4p 3s3p , =s,d Fano window resonan…
Harnack's Inequality for Parabolic De Giorgi Classes in Metric Spaces
J. Kinnunen, N. Marola, M. Miranda +1
In this paper we study problems related to parabolic partial differential equations in metric measure spaces equipped with a doubling measure and supporting a Poincare' inequality.…
Time-frequency representations of autoionization dynamics in helium
D. Busto, L. Barreau, M. Isinger +16
Autoionization, which results from the interference between direct photoionization and photoexcitation to a discrete state decaying to the continuum by configuration interaction, i…
Constraining Warm Dark Matter using QSO gravitational lensing
M. Miranda, A. V. Macciò
Warm Dark Matter (WDM) has been invoked to resolve apparent conflicts of Cold Dark Matter (CDM) models with observations on subgalactic scales. In this work we provide a new and in…
Continuous spectra in high-harmonic generation driven by multicycle laser pulses
W. Holgado, C. Hernández-GarcÃa, B. Alonso +5
We present observations of the emission of XUV continua in the 20-37 eV region by high harmonic generation (HHG) with - pulses focused onto a Kr gas jet. The und…
Photoemission time-delay measurements and calculations close to the 3s ionization minimum in Ar
D. Guenot, K. Klunder, C. L. Arnold +12
We present experimental measurements and theoretical calculations of photoionization time delays from the and shells in Ar in the photon energy range of 32-42 eV. The exp…
Q0045-3337: models including strong lensing by a spiral galaxy
M. Chieregato, M. Miranda, P. Jetzer
Aims. Falomo et al. (2005) discovered a disk-like galaxy at ~ 1.2 arcsec from the QSO Q0045-3337 by means of ESO VLT adaptive optics. They estimated a galaxy Einstein radius (for a…
All-optical transport and compression of ytterbium atoms into the surface of a solid immersion lens
M. Miranda, A. Nakamoto, Y. Okuyama +3
We present an all-optical method to load 174Yb atoms into a single layer of an optical trap near the surface of a solid immersion lens which improves the numerical aperture of a mi…
