Full counting statistics of weak measurement

A weak measurement consists in coupling a system to a probe in such a way that constructive interference generates a large output. So far, only the average output of the probe and its variance were studied. Here, the characteristic function for the moments of the output is provided. The outputs considered are not limited to the eigenstates of the pointer or of its conjugate variable, so that the results apply to any observable \Hat{o} of the probe. Furthermore, a family of well behaved complex quantities, the normal weak values, is introduced, in terms of which the statistics of the weak measurement can be described. It is shown that, within a good approximation, the whole statistics of weak measurement is described by a complex parameter, the weak value, and a real one.Comment: Expanded version: 9 pages, 3 Figs. Now the validity of the expansion for the moments is analysed. Introduced a one-parameter family of weak values, useful to express the correct characteristic function. More figures added.

Collective Bargaining in the Public Service of Canada: Bold Experiment or Act of Folly?

This brief background sketch of the Canadian labor relations scene suffices to indicate that several important impediments to the introduction of a full-fledged system of public service collective bargaining which exist in the United States have no counterpart north of the border. Particularly at the practical level, there were no insuperable hurdles to the enactment of the 1967 Canadian federal law. To understand how and why the new federal statute came to be enacted within this reasonably hospitable environment, it is important to trace the course of employment relations in the Canadian Public Service

Parodoxes of Canadian Legal Education

If the history of Canadian legal education should ever be written, these years of the mid-1970s will surely be viewed as a period of critical significance. For at least a quarter-century, growth has been the predominant theme: growth in student numbers and faculty complements; growth in democratic decision-making by both faculty and students, but also - inevitably - in the bureaucratic structures of faculties; growth of physical facilities and indeed, of whole new faculties; growth of libraries and of the pace and variety of research; growth of curricula and of teaching methods; growth in professional esteem and in public contribution; and - I believe - growth in quality throughout the entire system of legal education

Fairness at Work: Federal Labour Standards for the 21st Century

On October 30, 2006 Commissioner Harry Arthurs delivered his report Fairness at Work: Federal Labour Standards for the 21st Century to the Minister of Labour, the Hon. Jean-Pierre Blackburn

Industrial Unrest in Canada: A Diagnosis of Recent Experience

To diagnose the recent wave of industrial unrest in Canada, it is first of all necessary to indentify its characteristics. The two major dimensions of this phenomenon concern the source of union militancy and its illegal manifestations

Control of Ultra-cold Inelastic Collisions by Feshbash Resonances and Quasi-One-Dimensional Confinement

Cold inelastic collisions of atoms or molecules are analyzed using very general arguments. In free space, the deactivation rate can be enhanced or suppressed together with the scattering length of the corresponding elastic collision via a Feshbach resonance, and by interference of deactivation of the closed and open channels. In reduced dimensional geometries, the deactivation rate decreases with decreasing collision energy and does not increase with resonant elastic scattering length. This has broad implications; e.g., stabilization of molecules in a strongly confining two-dimensional optical lattice, since collisional decay of the highly vibrationally excited states due to inelastic collisions is suppressed. The relation of our results with those based on the Lieb-Liniger model are addressed.Comment: 5 pages, 1 figur
