Non–trivial Intertwined Second–order Recurrence Relations
In a recently published book, it is shown that there are essentially seven different non– trivial systems of three intertwined second–order recurrence relations, but the solutions are not given. In this note we present explicit solutions to all seven systems. AMS Classification: 11B39, 11B37
متن کاملAbsence of a static in-plane magnetic moment in the ‘hidden-order’ phase of URu2Si2
We have carried out a careful magnetic neutron scattering study of the heavy fermion compound URu2Si2 to probe the possible existence of a small magnetic moment parallel to tetragonal basal plane in the ‘hidden-order’ phase. This small in-plane component of the magnetic moment on the uranium sites S‖ has been postulated by two recent models (rank-5 superspin/hastatic order) aiming to explain th...
متن کاملOn the destruction of the hidden order in URu2Si2 by a strong magnetic field
We present a study of transport properties of the heavy fermion URu2Si2 in pulsed magnetic field. The large Nernst response of the hidden order state is found to be suppressed when the magnetic field exceeds 35 T. The combination of resistivity, Hall and Nernst data outlines the reconstruction of the Fermi surface in the temperature-field phase diagram. The zero-field ground state is a compensa...
متن کاملMagnetic monopoles over topologically non trivial Riemann Surfaces
An explicit canonical construction of monopole connections on non trivial U(1) bundles over Riemann surfaces of any genus is given. The class of monopole solutions depend on the conformal class of the given Riemann surface and a set of integer weights. The reduction of Seiberg-Witten 4-monopole equations to Riemann surfaces is performed. It is shown then that the monopole connections constructe...
متن کاملHidden topological order in the heavy fermion metal URu2Si2
We present a novel order parameter for the hidden order state of URu2Si2. We show via ab-initio calculation and low-energy effective tight-binding model that an incommensurate Fermi surface nesting in the partiallyfilled f -states renders a spin-orbit coupling density wave in the hidden-order state. An observable quantity for this order parameter is the polarized total angular momentum ∆mJ=±2, ...
