Long-lived nuclear spin states of magnetically equivalent protons by means of dissolution dynamic nuclear polarization

Nuclear Magnetic Resonance (NMR) is one of the most versatile techniques since it enables the characterization of solid, liquid and gaseous systems in a plethora of in-vitro and in-vivo experiments. Despite its multidisciplinary scope, it still suffers fro ...

Quantum numbers of the X(3872) state and orbital angular momentum in its rho(0)J/psi decay

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Luca Pescatore, Elena Graverini, Chitsanu Khurewathanakul, Renato Quagliani, Alessandro Mapelli, Zhirui Xu, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Maurizio Martinelli, Donal Patrick Hill, Cédric Potterat, Liang Sun, Pietro Marino, Mirco Dorigo, Xiaoxue Han, Sebastiana Gianì, Liupan An, Federico Leo Redi, Ilya Komarov, Thibaud Humair, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Barinjaka Rakotomiaramanana, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Adam Davis, Paolo Durante

Angular correlations in B+ -> X(3872)K+ decays, with X(3872) -> rho(0)J/psi, rho(0) -> pi(+)pi(-) and J/psi -> pi(+)pi(-), are used to measure orbital angular momentum contributions and to determine the J(PC) value of the X(3872) meson. The data correspond ...

Hyperpolarized para-Ethanol

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, Daniele Mammoli

We show that an imbalance between the populations of singlet (S) and triplet (T) states in pairs of magnetically equivalent spins can be generated by dissolution dynamic nudear polarization: In partly deuterated ethanol ((CD3CH2OD)-C-13), this T/S imbalanc ...

Comparing XMCD and DFT with STM spin excitation spectroscopy for Fe and Co adatoms on

Harald Brune, Stefano Rusponi, Pietro Gambardella, Markus Etzkorn, Anne Lehnert

We report on the magnetic properties of Fe and Co adatoms on a Cu2N/Cu(100)-c(2 x 2) surface investigated by x-ray magnetic dichroism measurements and density functional theory (DFT) calculations including the local coulomb interaction. We compare these re ...

Matrix product state applications for the ALPS project

Thierry Giamarchi, Timothée Ewart, Sébastien Keller

The density-matrix renormalization group method has become a standard computational approach to the low-energy physics as well as dynamics of low-dimensional quantum systems. In this paper, we present a new set of applications, available as part of the ALP ...

Composite charge 8/3 resonances at the LHC

Francesco Riva, Thibaud Vantalon

In composite Higgs models with partial compositeness, the small value of the observed Higgs mass implies the existence of light fermionic resonances, the top partners, whose quantum numbers are determined by the symmetry (and symmetry breaking) structure o ...

Observation of a new charged charmoniumlike state in B-0 -> J/psi K- pi(+) decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Tara Nanut, Ji Hyun Kim, Donghyun Kim, Xiao Wang

We present the results of an amplitude analysis of B-0 --> J/psi K- pi(+) decays. A new charged charmoniumlike state Z(c)(4200)(+) decaying to J/psi pi(+) is observed with a significance of 6.2 sigma. The mass and width of the Z(c)(4200)(+) are 4196(-29-13 ...

Effective Delivery of Analytes with Optofluidics for Ultrasensitive Biodetection

Hatice Altug, Arif Engin Cetin, Min Huang

We present a plasmonic nanobiosensor offering superior analyte delivery efficiency. Our experiments with virus-like analytes show more than an order of magnitude faster response time, and seven orders-of-magnitude dynamic concentration range for 10(3)-10(9 ...

Complete multi-field characterization of the geodesic acoustic mode in the TCV tokamak

Stefano Coda, Laurent Villard, Stephan Brunner, Laurie Porte, Zhouji Huang, Gabriele Merlo, Julien Stanislas Pierre Dominski, Thibaut Vernay, Cornelis Adrianus de Meijere

The geodesic acoustic mode (GAM) is a coherently oscillating zonal flow that may regulate turbulence in toroidal plasmas. Uniquely, the complete poloidal and toroidal structure of the magnetic component of the turbulence-driven GAM has been mapped in the T ...
