Ultrafast Photoelectron and Optical Spectroscopies of Photoinduced Processes in Molecular Systems in Solution

Investigating molecular excitations with femtosecond time resolution is of pivotal importance to understand the out-of-equilibrium processes taking place in molecular systems upon light absorption. The photochemistry of solvated species is heavily determin ...

A stability theory beyond the co-rotational setting for critical wave maps blow up

Joachim Krieger, Shuang Miao

We exhibit non-equivariant perturbations of the blowup solutions constructed in [18] for energy critical wave maps into

\mathbb{S}^2

. Our admissible class of perturbations is an open set in some sufficiently smooth topology and vanishes near the light co ...

Shapes of rotating normal fluid He-3 versus superfluid He-4 droplets in molecular beams

Christoph Bostedt, Andre Al Haddad

Previous single-pulse extreme ultraviolet and x-ray coherent diffraction studies revealed that superfluid He-4 droplets obtained in a free jet expansion acquire sizable angular momentum, resulting in significant centrifugal distortion. Similar experiments ...

Crystal electric field excitations in the quantum spin liquid candidate NaErS2

Christian Rüegg, Daniel Biner, Shang Gao

The delafossite family of compounds with a triangular lattice of rare earth ions has been recently proposed as a candidate host for quantum spin liquid (QSL) states. To realize QSLs, the crystal electric field (CEF) ground state of the rare earth ions shou ...

Real-Time Dynamics of the Formation of Hydrated Electrons upon Irradiation of Water Clusters with Extreme Ultraviolet Light

Marcel Drabbels, Andrew Daniel Bonnar Clark, Verónica Oliver Álvarez de Lara

Free electrons in a polar liquid can form a bound state via interaction with the molecular environment. This so-called hydrated electron state in water is of fundamental importance, e.g., in cellular biology or radiation chemistry. Hydrated electrons are h ...

Spin Polarization and Attosecond Time Delay in Photoemission from Spin Degenerate States of Solids

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

After photon absorption, electrons from a dispersive band of a solid require a finite time in the photoemission process before being photoemitted as free particles, in line with recent attosecond-resolved photoemission experiments. According to the Eisenbu ...

Comprehensive modeling of the band gap and absorption spectrum of BiVO4

Alfredo Pasquarello, Francesco Ambrosio, Julia Anna Wiktor, Igor Reshetnyak

We present first-principles calculations of the electronic structure of BiVO4 at various levels of theory. In the calculations, we take into account a series of effects that affect the band gap, i.e., spin-orbit coupling, electron-hole interaction, nuclear ...

The beam lines design for the CERN neutrino platform in the CERN north area and an outlook on their expected performance

Nikolaos Charitonidis

In the framework of the CERN Neutrino Platform project, extensions to the existing SPS North Area secondary beam lines "H2" and "H4", able to provide low-energy charged particles in the momentum range from 0.4 to 12 GeV/c, have been designed. The parameter ...

Collisional cross-section of water molecules in vapour studied by means of H-1 relaxation in NMR

Geoffrey Bodenhausen, Lothar Helm, Pascal Miéville, Daniele Mammoli, Roberto Buratto, Estel Canet Martinez

In gas phase, collisions that affect the rotational angular momentum lead to the return of the magnetization to its equilibrium (relaxation) in Nuclear Magnetic Resonance (NMR). To the best of our knowledge, the longitudinal relaxation rates R-1 = 1/T-1 of ...
