Topological implications in quantum tomography
How many measurement settings or outcomes are necessary in order to identify a quantum system which is constrained by prior information? We show that if the latter restricts the system to a set of lower dimensionality, then topological obstructions can increase the required number of outcomes (or binary settings) by a factor of two over the number of real parameters needed to characterize the s...
متن کاملSpatial charge inhomogeneity and defect states in topological Dirac semimetal thin films of Na3Bi
Topological Dirac semimetals (TDSs) are three-dimensional analogs of graphene, with carriers behaving like massless Dirac fermions in three dimensions. In graphene, substrate disorder drives fluctuations in Fermi energy, necessitating construction of heterostructures of graphene and hexagonal boron nitride (h-BN) to minimize the fluctuations. Three-dimensional TDSs obviate the substrate and sho...
متن کاملSubcategories of topological algebras
In addition to exploring constructions and properties of limits and colimits in categories of topological algebras, we study special subcategories of topological algebras and their properties. In particular, under certain conditions, reflective subcategories when paired with topological structures give rise to reflective subcategories and epireflective subcategories give rise to epireflective s...
متن کاملTopological implications of negative curvature for biological and social networks
Network measures that reflect the most salient properties of complex large-scale networks are in high demand in the network research community. In this paper we adapt a combinatorial measure of negative curvature (also called hyperbolicity) to parametrized finite networks, and show that a variety of biological and social networks are hyperbolic. This hyperbolicity property has strong implicatio...
متن کاملStabilizing synchrony by inhomogeneity
We show that for two weakly coupled identical neuronal oscillators with strictly positive phase resetting curve, isochronous synchrony can only be seen in the absence of noise and an arbitrarily weak noise can destroy entrainment and generate intermittent phase slips. Small inhomogeneity-mismatch in the intrinsic firing rate of the neurons-can stabilize the phase locking and lead to more precis...
