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 ...

Sn surface-enriched Pt–Sn bimetallic nanoparticles as a selective and stable catalyst for propane dehydrogenation

David Lyndon Emsley, Lidong Li

A new one pot, surfactant-free, synthetic route based on the surface organometallic chemistry (SOMC) concept has been developed for the synthesis of Sn surface-enriched Pt-Sn nanoparticles. Bu3SnH selectively reacts with [Pt]-H formed in situ at the surfac ...

Heteronuclear proton double quantum-carbon single quantum scalar correlation in solids

David Lyndon Emsley

A new NMR experiment that exploits the advantages of proton double quantum (DQ) NMR through a proton DQ-carbon single quantum (SQ) correlation experiment in the solid state is proposed. Analogous to the previously proposed 2D H-1 (DQ)-C-13 refocused INEPT ...

Ab initio self-consistent total-energy calculations within the EXX/RPA formalism

Nicola Colonna, Ngoc Linh Nguyen

Calculations of exact-exchange (EXX) and random phase approximation (RPA)-correlation energies within the formally exact adiabatic connection fluctuation-dissipation theorem formalism have recently been carried out for a number of isolated and condensed sy ...

Crystals of Bound States in the Magnetization Plateaus of the Shastry-Sutherland Model

Frédéric Mila

Using infinite projected entangled-pair states, we show that the Shastry-Sutherland model in an external magnetic field has low-magnetization plateaus which, in contrast to previous predictions, correspond to crystals of bound states of triplets, and not t ...

Playing quantum hide-and-seek with the muon: localizing muon stopping sites

Nicola Marzari

The most fundamental limitations of a muon-spin relaxation experiment can be the lack of knowledge of the implantation site of the muon and the uncertainty about the muon's perturbation of its host. Here we review some of the work done on the 'muon site pr ...

A Classical and Quantum Trajectory Description of Nonadiabatic Dynamics within Time-Dependent Density Functional Theory

Basile Curchod

Characterizing and predicting the nuclear dynamics of electronically excited molecules is of paramount importance to the understanding of photochemical and photophysical processes in molecules and to the development of new technologies in domains like sola ...

Nonlinear Quantum Optomechanics via Individual Intrinsic Two-Level Defects

Tobias Kippenberg, Vivishek Sudhir

We propose to use the intrinsic two-level system (TLS) defect states found naturally in integrated optomechanical devices for exploring cavity QED-like phenomena with localized phonons. The Jaynes-Cummings-type interaction between TLS and mechanics can rea ...

Initial or final values for semiclassical evolutions in the Weyl–Wigner representation

David Eduardo Zambrano Ramirez

Initial value representations are constructed to avoid the search for trajectories that are only defined in semiclassical approximations by their boundary conditions. We show how to incorporate these procedures within the full Weyl representation, so that ...

Systematic approach to thermal leptogenesis

Tibor Frossard

In this work we study thermal leptogenesis using nonequilibrium quantum field theory. Starting from fundamental equations for correlators of the quantum fields we describe the steps necessary to obtain quantum-kinetic equations for quasiparticles. These ca ...
