Monte-Carlo simulation of events with Drell-Yan lepton pairs from antiproton-proton collisions

A. Bianconi, M. Radici

The complete knowledge of the nucleon spin structure at leading twist requires also addressing the transverse spin distribution of quarks, or transversity, which is yet unexplored…

ATHENA -- First Production of Cold Antihydrogen and Beyond

ATHENA Collaboration, A. Kellerbauer, M. Amoretti +33

Atomic systems of antiparticles are the laboratories of choice for tests of CPT symmetry with antimatter. The ATHENA experiment was the first to report the production of copious am…

Cavity QED quantum phase gates for a single longitudinal mode of the intracavity field

R. García--Maraver, R. Corbalán, K. Eckert +3

A single three-level atom driven by a longitudinal mode of a high-Q cavity is used to implement two-qubit quantum phase gates for the intracavity field. The two qubits are associat…

Quantum theory of a polarization phase-gate in an atomic tripod configuration

S. Rebic, D. Vitali, C. Ottaviani +4

We present the quantum theory of a polarization phase-gate that can be realized in a sample of ultracold rubidium atoms driven into a tripod configuration. The main advantages of t…

Production of Cold Antihydrogen with ATHENA for Fundamental Studies

ATHENA Collaboration, A. Kellerbauer, M. Amoretti +33

Since the beginning of operations of the CERN Antiproton Decelerator in July 2000, the successful deceleration, storage and manipulation of antiprotons has led to remarkable progre…

Nonlinear extensions of Schrödinger-von Neumann quantum dynamics: a list of conditions for compatibility with thermodynamics

Gian Paolo Beretta

We propose a list of conditions that consistency with thermodynamics imposes on linear and nonlinear generalizations of standard unitary quantum mechanics that assume a set of true…

The First Cold Antihydrogen

M. C. Fujiwara, M. Amoretti, C. Amsler +29

Antihydrogen, the atomic bound state of an antiproton and a positron, was produced at low energy for the first time by the ATHENA experiment, marking an important first step for pr…

Detection of antihydrogen annihilations with a Si-micro-strip and pure CsI detector

I. Johnson

In 2002, the ATHENA collaboration reported the creation and detection of cold (~15 K) antihydrogen atoms [1]. The observation was based on the complete reconstruction of antihydrog…

Sodium Doped LaMnO3 Thin Films: Influence of Substrate and Thickness on Physical Properties

Lorenzo Malavasi, Maria Cristina Mozzati, Ivano Alessandri +3

In this paper we report the results about the synthesis and characterization of optimally doped La1-xNaxMnO3 thin films grown onto SrTiO3 (100), NdGaO3 (100) and NdGaO3 (110) for t…
