Wilson Holonomy and Spectral Monodromy in Spin-Orbit Rings: Effective Gauge Connections and Loop Observables
N. Bolivar
A spin-orbit Hamiltonian with an effective gauge structure carries two distinct loop objects that are routinely conflated: an energy-independent Wilson holonomy, which organizes in…
Adiabatic Anisotropic Gravitational Collapse in Painlevé-Gullstrand Coordinates: A Geometric Analysis
G. Abellán, N. Bolívar, A. Alexandrova +1
We present a detailed geometric analysis of adiabatic, anisotropic gravitational collapse formulated in a single Painlevé-Gullstrand coordinate system that covers both the interior…
Warp drive solutions in spherical coordinates with anisotropic matter configurations
Gabriel Abellán, Nelson Bolívar, Ivaylo Vasilev
In this work we study the influence of isotropic and anisotropic fluids on the spherically symmetric warp metric. We evaluate the energy conditions and the influence of including a…
Equilibrium currents in a Corbino graphene ring
A. López, N. Bolívar, E. Medina +1
We address the description of a graphene Corbino disk in the context of a tight binding approach that includes both kinetic and Rashba spin-orbit coupling due to an external out-of…
Charge and spin polarized currents in mesoscopic rings with Rashba spin-orbit interactions coupled to an electron reservoir
Michael Ellner, Nelson Bolívar, Bertrand Berche +1
The electronic states of a mesoscopic ring are assessed in the presence of Rashba Spin Orbit coupling and a gauge field. Spin symmetric coupling to an ideal lead is implemen…
Comment on "Equilibrum spin currents: Non-Abelian Gauge Invariance and Color Diamagnetism in Condensed Matter"
Alexander López, Ernesto Medina, Nelson Bolívar +1
In a recent paper [Phys. Rev. Lett. 101, 106601], I. V. Tokatly addresses a non Abelian formulation of spin orbit interaction in condensed matter, restricting to a gauge symmetric…
