Valuation Extensions of Filtered and Graded Algebras
C. Baetica, F. Van Oystaeyen
In this note we relate the valuations of the algebras appearing in the non-commutative geometry of quantized algebras to properties of sub-lattices in some vector spaces. We consid…
Some bialgebroids constructed by Kadison and Connes-Moscovici are isomorphic
Florin Panaite, Freddy Van Oystaeyen
We prove that a certain bialgebroid introduced recently by Kadison is isomorphic to a bialgebroid introduced earlier by Connes and Moscovici. At the level of total algebras, the is…
Quantum rings as electron spin beam splitters
Peter Foldi, Orsolya Kalman, Mihaly G. Benedict +1
Quantum interference and spin-orbit interaction in a one-dimensional mesoscopic semiconductor ring with one input and two output leads can act as a spin beam splitter. Different po…
A structure theorem for quasi-Hopf comodule algebras
Florin Panaite, Freddy Van Oystaeyen
If H is a quasi-Hopf algebra and B is a right H-comodule algebra such that there exists v:H\to B a morphism of right H-comodule algebras, we prove that there exists a left H-module…
Tracing large-scale structure at high redshift with Lyman-alpha emitters: the effect of peculiar velocities
P. Monaco, P. Moller, J. Fynbo +3
We investigate the effect of peculiar velocities on the redshift space distribution of z>~2 galaxies, and we focus in particular on Ly-alpha emitters. We generate catalogues of dar…
Microwave emission from a crystal of molecular magnets -- The role of a resonant cavity
Mihaly G. Benedict, Peter Foldi, F. M. Peeters
We discuss the effects caused by a resonant cavity around a sample of a magnetic molecular crystal (such as Mn-Ac), when a time dependent external magnetic field is applie…
