Effect of residual Bose-Einstein correlations on the Dalitz plot of hadronic charm meson decay

We show that the presence of residual Bose-Einstein correlations may affect the resonant contribution of hadronic charm decays where two identical pions appear in the final state. The distortion of the phase space of the reaction would be visible in the dalitz plot. The decay D+ --> K- pi+ pi+ is discussed but results can be generalized to any decay with identical bosons.Comment: 12 pages, included 4 figures. Submitted Phys. Lett.

Are the hosts of VLBI selected radio-AGN different to those of radio-loud AGN?

Recent studies have found that radio-AGN selected by radio-loudness show little difference in terms of their host galaxy properties when compared to non-AGN galaxies of similar stellar mass and redshift. Using new 1.4~GHz VLBI observations of the COSMOS field we find that approximately 49$\pm8$\% of high-mass (M $>$ 10$^{10.5}$ M$_{\odot}$), high luminosity (L$_{1.4}$ $>$ 10$^{24}$ W~Hz$^{-1}$) radio-AGN possess a VLBI detected counterpart. These objects show no discernible bias towards specific stellar masses, redshifts or host properties other than what is shown by the radio-AGN population in general. Radio-AGN that are detected in VLBI observations are not special, but form a representative sample of the radio-loud AGN population.Comment: 6 pages, 4 figures, lette

Measuring multipole moments of Weyl metrics by means of gyroscopes

Using the technique of Rindler and Perlick we calculate the total precession per revolution of a gyroscope circumventing the source of Weyl metrics. We establish thereby a link between the multipole moments of the source and an ``observable'' quantity. Special attention deserves the case of the gamma-metric. As an extension of this result we also present the corresponding expressions for some stationary space-times.Comment: 18 pages Latex, To appear in J.Math.Phy

Creation of quantum error correcting codes in the ultrastrong coupling regime

We propose to construct large quantum graph codes by means of superconducting circuits working at the ultrastrong coupling regime. In this physical scenario, we are able to create a cluster state between any pair of qubits within a fraction of a nanosecond. To exemplify our proposal, creation of the five-qubit and Steane codes is numerically simulated. We also provide optimal operating conditions with which the graph codes can be realized with state-of-the-art superconducting technologies.Comment: Added a new appendix sectio

The Emerging Legal Architecture for Social Justice

Lawyers advocating for social change are now front and center in newspapers and social media. This article discusses how a new breed of progressive lawyers envision social justice law practice today. These “critical lawyers” are diverse in background, gender, ethnicity and race. They see law as a complex, contradictory tool rather than a necessary and sufficient route to justice. Their practices differ from the traditional non-profit public interest firms of the earlier generation that assumed justice would result if law and lawyers were accessible. To highlight the differences, the article discusses the law practices of Beyond Legal Aid, Law for Black Lives, and TIME’s UP. Beyond Legal Aid is redesigning legal services to produce community partnerships. Law for Black Lives provides legal services to ensure greater equity in criminal procedures. TIME’s UP is radically revising how women respond to sexual harassment at the workplace. These practices seek to democratize the use of law to advance social justice by developing community and client collaborations. The practices rely on revenue from many sources including client fees, small donations through on-line platforms, and volunteer expertise. They seek to develop structures that can provide sustainability, flexibility, and growth including nodes and network models that allows linkage across varied practice sites. Using technology, the central node can serve a network that can stretch across geographic locations and types of organizations. This new architecture requires support from a variety of sources including law schools and peer support groups all of which enable the sharing of ideas and innovations
