Quantum theory of the mazer. II. Extensions and experimental considerations
Markus Löffler,Markus Löffler,Markus Löffler,Georg M. Meyer,Georg M. Meyer,Georg M. Meyer,Michael Schröder,Michael Schröder,Marlan O. Scully,Marlan O. Scully,Herbert Walther,Herbert Walther +11 more
TL;DR: In this article, the quantum theory of the mazer is extended by giving exact analytical solutions for a smooth potential and comparing them with the mesa potential considered earlier, leading to interesting features such as a state-changing or state-preserving mirror for atoms.
Proposal for a Joint German-British Interferometric Gravitational Wave Detector
J. H. Hough,B. J. Meers,G. P. Newton,N. A. Robertson,H. Ward,G. Leuchs,Timothy M. Niebauer,Albrecht Rüdiger,Roland Schilling,L. Schnupp,Herbert Walther,Walter Winkler,B. F. Schutz,Jürgen Ehlers,P. Kafka,Gerhard Schäfer,M.W. Hamilton,I. Schutz,Herbert Welling,J. R. J. Bennett,I. F. Corbett,B. W. H. Edwards,R. J. S. Greenhalgh,V. Kose +23 more
TL;DR: In this article, the authors present their case for this collaborative venture and outline the design philosophy of their proposed instrument - an interferometric detector with arms of length close to 3km.
Journal ArticleDOI
Feynman’s approach to negative probability in quantum mechanics
TL;DR: In this paper, the authors introduce the concept of negative probability in the context of Young's double-slit experiment and in doing so shed a new light on the problem and emphasize that negative probability yields useful insight into the EPR problem.
Journal ArticleDOI
Quantum theory of the mazer. III. Spectrum
Michael Schröder,Michael Schröder,K. Vogel,Wolfgang P. Schleich,Wolfgang P. Schleich,Marlan O. Scully,Marlan O. Scully,Herbert Walther,Herbert Walther +8 more
TL;DR: In this article, the spectrum of the micromaser with quantized motion of the pump atoms is calculated in different velocity regimes and the authors present approximate analytical results for the spectrum that allow a comparison with the exact numerical calculations.
Journal ArticleDOI
Nonclassical interference effects in the radiation from coherently driven uncorrelated atoms
C. Skornia,C. Skornia,J. von Zanthier,Girish S. Agarwal,Girish S. Agarwal,E. Werner,Herbert Walther +6 more
TL;DR: In this article, the existence of nonclassical correlations in the radiation of two atoms, that are coherently driven by a continuous laser source, was demonstrated, and the correlations are induced by state reduction due to the measurement process when the detection of the photons does not distinguish between the atoms.
