The Role of Grain Boundaries in Determining the Transport Properties in Magnetite

David C. Mertens, W. Montfrooij, R. J. McQueeney +2

We present magnetoresistance and Hall-effect measurements on single crystal magnetite Fe3O4 close to the Verwey transition Tv = 123.8 K. We show that the formation of grain boundar…

Effective operators within the ab initio no-core shell model

Ionel Stetcu, Bruce R. Barrett, Petr Navratil +1

We implement an effective operator formalism for general one- and two-body operators, obtaining results consistent with the no-core shell model (NCSM) wave functions. The Argonne V…

On diffusivity of a tagged particle in asymmetric zero-range dynamics

Sunder Sethuraman

Consider a tagged particle in zero-range dynamics on the integer lattice in dimension d with rate g whose finite-range jump probabilities p possess a drift. We show, in equilibrium…

Topological Hysteresis in the Intermediate State of Type-I Superconductors

Ruslan Prozorov, Russell W. Giannetta, Anatolii A. Polyanskii +1

Magneto-optical imaging of thick stress-free lead samples reveals two distinct topologies of the intermediate state. Flux tubes are formed upon magnetic field penetration (closed t…

Dissipation and coherent effects in narrow superconducting channels

M. Amin Kayali, Vladimir G. Kogan, Valery L. Pokrovsky

We apply the time dependent Ginzburg-Landau equations (TDGL) to study small ac currents of frequency in superconducting channels narrow on the scale of London penetration depth…

Jointly hyponormal pairs of commuting subnormal operators need not be jointly subnormal

Raul Curto, Jasang Yoon

We construct three different families of commuting pairs of subnormal operators, jointly hyponormal but not admitting commuting normal extensions. Each such family can be used to a…
