The Fuzzy Quantum Proton in the Hydrogen Chloride Hydrates

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 ...

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 ...

Hydrogen adsorption in the metal-organic frameworks Fe2(dobdc) and Fe2(O2)(dobdc)

Wendy Lee Queen

The hydrogen storage properties of Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) and an oxidized analog, Fe2(O2)(dobdc), have been examd. using several complementary techniques, including low-pressure gas adsorption, neutron powder diffractio ...

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 ...

Can CoGeNT and DAMA modulations be due to Dark Matter?

Duccio Pappadopulo

We explore the dark matter interpretation of the anomalies claimed by the DAMA and COGENT experiments, in conjunction with the various null direct-detection experiments. An independent analysis of the COGENT data is employed and several experimental and as ...

Experimental evidence of librational vibrations determining the stability of calcium borohydride

Pascal Martelli

The high energy of hydrogen vibrations in solids is the origin of their strong impact on thermodynamic properties. The peculiar structure of complex hydrides amplifies this impact. We shed light on the vibrational properties of three allotropes of Ca(BH4)2 ...

Deep inelastic scattering in conformal QCD

We consider the Regge limit of a CFT correlation function of two vector and two scalar operators, as appropriate to study small-x deep inelastic scattering in N = 4 SYM or in QCD assuming approximate conformal symmetry. After clarifying the nature of the R ...

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 ...

AdS Black Disk Model for Small-x Deep Inelastic Scattering

Using the approximate conformal invariance of QCD at high energies we consider a simple anti- de Sitter black disk model to describe saturation in deep inelastic scattering. Deep inside saturation the structure functions have the same power law scaling, F( ...
