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

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 ...

Anomalous thermal decoherence in a quantum magnet measured with neutron spin echo spectroscopy

Thomas Keller, Felix Groitl

The effect of temperature dependent asymmetric line broadening is investigated in Cu(NO3)(2)center dot 2.5D(2)O, a model material for a one-dimensional bond alternating Heisenberg chain, using the high resolution neutron-resonance spin echo (NRSE) techniqu ...

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 ...

FIRST NuSTAR OBSERVATIONS OF MRK 501 WITHIN A RADIO TO TeV MULTI-INSTRUMENT CAMPAIGN

Xin Chen, Thomas Günther Bretz

We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR. During the campaign, the nearby BL La ...

A Large Hadron Electron Collider at CERN. Report on the Physics and Design Concepts for Machine and Detector

Tatiana Pieloni, Stephan Russenschuck, Werner Friedrich Herr, Yan Hao, Ngoc Thanh Trinh, José Luis Abelleira Fernández, Frank Zimmermann

The physics programme and the design are described of a new collider for particle and nuclear physics, the Large Hadron Electron Collider (LHeC), in which a newly built electron beam of 60 GeV, to possibly 140 GeV, energy collides with the intense hadron b ...

The Fuzzy Quantum Proton in the Hydrogen Chloride Hydrates

Michele Ceriotti, Michele Parrinello

The motion of the excess proton is understood as a process involving interconversion between two limiting states, namely, the Eigen and Zundel cations. Nuclear quantum effects (NQE) and the organization of the surrounding solvent play a significant role in ...

Simultaneous measurement of lithium and fluorine momentum in

Michele Ceriotti

We present momentum widths and mean kinetic energies of lithium and fluorine in 7LiF, as determined simultaneously from deep inelastic neutron scattering (DINS) measurements. Experimental data across a temperature range from 4 to 300K are presented, and th ...

Efficient First-Principles Calculation of the Quantum Kinetic Energy and Momentum Distribution of Nuclei

Michele Ceriotti

Light nuclei at room temperature and below exhibit a kinetic energy which significantly deviates from the predictions of classical statistical mechanics. This quantum kinetic energy is responsible for a wide variety of isotope effects of interest in fields ...

Synthesis and Physical Properties of Low Dimensional Quantum Magnets

Goran Nilsen

Strong electron correlation lies at the root of many quantum collective phenomena observed in solids, including high Tc superconductivity. Theoretically, the problem of many interacting electrons is difficult to treat, however, and a microscopic understand ...

Nuclear quantum effects in ab initio dynamics: Theory and experiments for lithium imide

Michele Ceriotti, Giacomo Francesco Leonardo Miceli, Michele Parrinello

Owing to their small mass, hydrogen atoms exhibit strong quantum behavior even at room temperature. Including these effects in first-principles calculations is challenging because of the huge computational effort required by conventional techniques. Here w ...
