Analysis of complete positivity conditions for quantum qutrit channels

We present an analysis of complete positivity (CP) constraints on qutrit quantum channels that have a form of affine transformations of generalized Bloch vector. For diagonal (damping) channels we derive conditions analogous to the ones that in qubit case produce tetrahedron structure in the channel parameter space.Comment: 12 pages, 8 figures (.eps), minor changes in the text and formula

Using the Theories of Exit, Voice, Loyalty, and Procedural Justice to Reconceptualize Brazil’s Rejection of Bilateral Investment Treaties

In the past decade, investor-state arbitration has made tremendous gains in both credibility and use. There is now widespread accession to the Convention on the Settlement of Investment Disputes between States and Nationals of Other States. States have executed more than 2,000 bilateral investment treaties (BITs) defining the terms and conditions under which one (“investor”) state’s nationals and companies will invest in the other (“host”) state. Such terms include provisions allowing foreign investors to initiate arbitration proceedings against the host state, and at this point, more than 500 disputes have been submitted to investor-state arbitration. There is, however, one very notable example of a rapidly developing state that has rejected this system of international dispute resolution in favor of nation-level structures. That example is the largely industrialized state of Brazil. This Article begins by describing the economic and political context within which Brazil began its consideration of BITs. Then, this Article recounts Brazil’s history with BITs in some detail and examines alternative investment protection legislation adopted in Brazil. This Article then turns to Hirschman’s theory of exit, voice, and loyalty, as well as the theories and research of procedural justice, to apply them to Brazil’s history with BITs and to consider the particular relationship between procedural justice and loyalty. Ultimately, the Article urges that Hirschman’s theory and the theories and research regarding procedural justice encourage a reconceptualization of Brazil’s alleged “failure” in choosing not to ratify the BITs that had been negotiated by its diplomats

Phoebe 2.0 – Triple and multiple systems

Some close binary formation theories require the presence of a third body so that the binary orbit can shrink over time. Tidal friction and Kozai cycles transfer energy from the binary to its companion, resulting in a close inner binary and a wide third body orbit. Spectroscopy and imaging studies have found 40% of binaries with periods less than 10 days, and 96% with periods less than 3 days, have a wide tertiary companion. With recent advancements in large photometric surveys, we are now beginning to detect many of these triple systems by observing tertiary eclipses or through the effect they have on the eclipse timing variations (ETVs) of the inner-binary. In the sample of 2600 Kepler EBs, we have detected the possible presence of a third body in ∼20%, including several circumbinary planets. Some multiple systems are quite dynamical and feature disappearing and reappearing eclipses, apsidal motion, and large disruptions to the inner-binary. phoebe is a freely available binary modeling code which can dynamically model all of these systems, allowing us to better test formation theories and probe the physics of eclipsing binaries

Red-giant stars in eccentric binaries

The unparalleled photometric data obtained by NASA’s Kepler Space Telescope has led to improved understanding of red-giant stars and binary stars. We discuss the characterization of known eccentric system, containing a solar-like oscillating red-giant primary component. We also report several new binary systems that are candidates for hosting an oscillating companion. A powerful approach to study binary stars is to combine asteroseimic techniques with light curve fitting. Seismology allows us to deduce the properties of red giants. In addition, by modeling the ellipsoidal modulations we can constrain the parameters of the binary system. An valuable independent source are ground-bases, high-resolution spectrographs

Computing a Knot Invariant as a Constraint Satisfaction Problem

We point out the connection between mathematical knot theory and spin glass/search problem. In particular, we present a statistical mechanical formulation of the problem of computing a knot invariant; p-colorability problem, which provides an algorithm to find the solution. The method also allows one to get some deeper insight into the structural complexity of knots, which is expected to be related with the landscape structure of constraint satisfaction problem.Comment: 6 pages, 3 figures, submitted to short note in Journal of Physical Society of Japa
