Experimental station Bernina at SwissFEL: condensed matter physics on femtosecond time scales investigated by X-ray diffraction and spectroscopic methods
Christoph Peter Hauri, Paul Beaud, Christopher Alexander Arrell, Giulia Fulvia Mancini, Jochen Rittmann
The Bernina instrument at the SwissFEL Aramis hard X-ray free-electron laser is designed for studying ultrafast phenomena in condensed matter and material science. Ultrashort pulses from an optical laser system covering a large wavelength range can be used ...
International Union of Crystallography (IUCr)2019Spin polarization and attosecond time delay in photoemission from solids
In the photoemission process electrons are emitted from a solid upon excitation with UV light. From the measurement of their energy and momentum, angle-resolved photoemission spectroscopy (ARPES) allows to reconstruct the electronic properties of the solid ...
EPFL2018Spatio-temporal observation of dynamical structures in order-disorder phenomena and phase transitions via Ultrafast Electron Diffraction
The development of ultrafast time-resolved techniques in the last decades allowed the direct observation of out-of-equilibrium transient states and dynamical processes up to then hidden in many different fields, ranging from chemistry to solid state physic ...
EPFL2018First-Principles Statistical Mechanics of Multicomponent Crystals
The importance of configurational, vibrational, and electronic excitations in crystalline solids of technological interest makes a rigorous treatment of thermal excitations an essential ingredient in first-principles models of materials behavior. This cont ...
Annual Reviews2018The LOUVRE Laboratory: State-of-the-Art Ultrafast Ultraviolet Spectroscopies for Molecular and Materials Science
Majed Chergui, Natalia Nagornova, Frank van Mourik, Edoardo Baldini, Thomas Charles Henry Rossi, Malte Oppermann, Tania Palmieri, Lars-Hendrik Mewes, Benjamin Bauer, Aurelio Oriana
We describe the facilities for ultraviolet studies in the femtosecond to nanosecond time domain. These facilities consist of: i) a set-up for deep-ultraviolet spectroscopy in the 260–380 nm range in both pump and probe pulses for transient absorption/refle ...
2017Simulating Energy Relaxation in Pump-Probe Vibrational Spectroscopy of Hydrogen-Bonded Liquids
We introduce a nonequilibrium molecular dynamics simulation approach, based on the generalized Langevin equation, to study vibrational energy relaxation in pump probe spectroscopy. A colored noise thermostat is used to selectively excite a set of vibration ...
Amer Chemical Soc2017Multilaser Conformer-Selective Spectroscopy of Cold Biomolecular Ions in the Gas Phase
Proteins and even small peptides play crucial role in almost any biological. Biological activity and functionality of these building blocks of life are determined not only by their primary structure, but also by their 3D orientation â secondary, tertiary ...
EPFL2017Recent improvements on micro-thermocouple based SThM
The scanning thermal microscope (SThM) has become a versatile tool for local surface temperature mapping or measuring thermal properties of solid materials. In this article, we present recent improvements in a SThM system, based on a micro-wire thermocoupl ...
Iop Publishing Ltd2017Dynamic nuclear polarization at 40 kHz magic angle spinning
David Lyndon Emsley, Moreno Lelli, Pierrick Berruyer, David Benjamin Roger Antoine Gajan
DNP-enhanced solid-state NMR spectroscopy under magic angle spinning (MAS) is rapidly developing into a powerful analytical tool to investigate the structure of a wide range of solid materials, because it provides unsurpassed sensitivity gains. Most develo ...
Royal Society of Chemistry2016The finite element square reduced (FE2R) method with GPU acceleration: towards three-dimensional two-scale simulations
The FE2 method is a renown computational multiscale simulation technique for solid materials with fine-scale microstructure. It allows for the accurate prediction of the mechanical behavior of structures made of heterogeneous materials with nonlinear mater ...
