Galois conjugated tensor fusion categories and non-unitary CFT

We provide a generalisation of the matrix product operator (MPO) formalism for string-net projected entangled pair states (PEPS) to include non-unitary solutions of the pentagon equation. These states provide the explicit lattice realisation of the Galois conjugated counterparts of (2+1) dimensional TQFTs, based on tensor fusion categories. Although the parent Hamiltonians of these renormalisation group fixed point states are non-Hermitian, many of the topological properties of the states still hold, as a result of the pentagon equation. We show by example that the the topological sectors of the Yang-Lee theory (the non-unitary counterpart of the Fibonacci fusion category) can be constructed even in the absence of closure under Hermitian conjugation of the basis elements of the Ocneanu tube algebra. We argue that this can be generalised to the non-unitary solutions of all $SU(2)$ level $k$ models. The topological sector construction is demonstrated by applying the concept of strange correlators to the Yang-Lee model, giving rise to a non-unitary version of the classical hard hexagon model in the Yang-Lee universality class and obtaining all generalised twisted boundary conditions on a finite cylinder of the Yang-Lee edge singularity.Comment: 5 pages, 1 figur

Lehan K. Tunks—A Tribute

Lee Tunks came to New Jersey as Dean of the two Rutgers Law Schools (Newark and Camden) in 1953 and served until 1962. Rutgers Law School had been only recently created; it had come into being in 1948 (from the merger of several municipal and private schools) as the law school of the contemporaneously created state university, Rutgers University. Lee\u27s charge and purpose was to build a major state law school. He had to position the school as a high priority claimant upon university resources: to effect large increases in library collection and staff, to break his faculty\u27s salaries free from the university pattern, to acquire research and administrative resources, all of which generated disputes within the university. He led the faculty to decisions that entangled the newly visible public institution in external fights with bar, alumni, or the legislature. There was one year in which Newark admissions standards were so boosted as to cut the entering class by almost 50%, and there was a several-year campaign to drop the school\u27s evening division as beyond its resources. All these disputes were intensified by the dedication and passion with which Lee pressed his positions, but it was the same dedication coupled with a superior tactical sense which saw them mostly won on Lee\u27s terms

Lehan K. Tunks—A Personal Recollection

What follows are some observations about Lee Tunks, formed during my several years of assisting him with deaning duties at the Law School, and during the years since when we have been faculty colleagues and friends. I always think of Lee as a law school dean. Perhaps that is because he was a dean when I first met him. Perhaps it is because what I really know about deans and deaning I learned first from him. Whatever the cause, he seems to me to be one of those people destined to be a law school dean. I have known many fine deans since those days, but most feel the job is one they didn\u27t plan on having and one they will someday (hopefully soon) be well rid of. By contrast, Lee Tunks seemed to the manor born

Parity violation and the nature of charges

The origin of parity violation in physics is still unknown. At the present time, it is introduced in the theory by requiring that the SU(2) subgroup entering the description of interactions involves the left components. In the present contribution, one elaborates upon a suggestion made by Landau that particles and antiparticles could be like "stereo-isomeric" molecules, which would naturally provides parity violation. Particles and antiparticles could thus be combinations of the parity doublets associated with a chiral symmetry realized in the Wigner-Weyl mode. Consequences of such a description and the possible problems it could raise are examined.Comment: 3 pages, contribution to the 3rd international workshop: "From parity violation to hadronic structure and more ..."
