Design of Separated Element Reflector Experiments in CROCUS: PETALE

Andreas Pautz, Vincent Pierre Lamirand, Pavel Frajtag, Mathieu Hursin, Daniel Jerôme Siefman

The present article describes the preliminary design studies for PETALE (Programme d'Etude en Transmission de l'Acier Lourd et ses Elements), an oncoming experimental program in the CROCUS reactor. Within the framework of the Venus-Eole-Proteus collaborati ...

Quantum Motional Sideband Asymmetry in the Presence of Kerr-type Nonlinearities

Tobias Kippenberg, Liu Qiu, Itay Shomroni, Marie Adrienne Ioannou

Sideband asymmetry between the Stokes and anti-Stokes scattering is a signature of the mechanical oscillators in the quantum regime. It has been demonstrated in several optomechanical systems, as a self-calibrated thermometry method. We present motional si ...

Plasmon-less surface enhanced Raman spectra induced by self-organized networks of silica nanoparticles produced by femtosecond lasers

Yves Bellouard, Erica Kathleen Block

Raman spectroscopy is the workhorse for label-free analysis of molecules. It relies on the inelastic scattering of incoming monochromatic light impinging molecules of interest. This effect leads to a very weak emission of light spectrum that provides a sig ...

Magnetic Excitations and Electronic Interactions in Sr2CuTeO6: A Spin-1/2 Square Lattice Heisenberg Antiferromagnet

Henrik Moodysson Rønnow, Oleg Yazyev, Peter Babkevich, Vamshi Mohan Katukuri

Sr2CuTeO6 presents an opportunity for exploring low-dimensional magnetism on a square lattice of S = 1/2 Cu2+ ions. We employ ab initio multireference configuration interaction calculations to unravel the Cu2+ electronic structure and to evaluate exchange ...

Spin excitations in the skyrmion host Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Peter Babkevich, Jonathan White, Ping Huang, Felix Groitl, Gregory Scott Tucker

We have used inelastic neutron scattering to measure the magnetic excitation spectrum along the high-symmetry directions of the first Brillouin zone of the magnetic skyrmion hosting compound Cu2OSeO3. The majority of our scattering data are consistent with ...

Importance of rotationally inelastic processes in low-energy Penning ionization of CHF3

Andreas Osterwalder, Justinas Jankunas

Low energy reaction dynamics can strongly depend on the internal structure of the reactants. The role of rotationally inelastic processes in cold collisions involving polyatomic molecules has not been explored so far. Here we address this problem performin ...

State-to-state scattering of CH₄ from Ni(111) and Gr/Ni(111)

Maarten Eduard van Reijzen

In this thesis, I describe the design and implementation of the first state-to-state surface scattering experiments for methane from clean single crystalline surfaces in ultrahigh vacuum. The experiments use infrared laser pumping to prepare the incident C ...

Nuclear Quantum Effects in Water and Aqueous Systems: Experiment, Theory, and Current Challenges

Michele Ceriotti, Wei Fang

Nuclear quantum effects influence the structure and dynamics of hydrogen-bonded systems, such as water, which impacts their observed properties with widely varying magnitudes. This review highlights the recent significant developments in the experiment, th ...

Spin wave excitations in the tetragonal double perovskite Sr2CuWO6

Sami Juhani Vasala

Sr2CuWO6 is a double perovskite proposed to be at the border between two- and three-dimensional magnetism, with a square lattice of S = 1/2 Cu2+ ions. We have used inelastic neutron scattering to investigate the spin wave excitations of the system, to find ...

Nuclear Quantum Effects in Water at the Triple Point: Using Theory as a Link Between Experiments

Michele Ceriotti, Bingqing Cheng

One of the most prominent consequences of the quantum nature of light atomic nuclei is that their kinetic energy does not follow a Maxwell-Boltzmann distribution. Deep inelastic neutron scattering (DINS) experiments can measure this effect. Thus, the nucle ...
