Non-Abelian monopoles in the multiterminal Josephson effect
نویسندگان
چکیده
In this work we present a detailed theoretical analysis for the spectral properties of Andreev bound states in multiterminal Josephson junctions by employing symmetry-constrained scattering matrix approach. We find that synthetic multidimensional space superconducting phases, crossings bands may support non-Abelian SU(2) monopoles with topological charge characterized second class Chern number. propose these defects can be detected via nonlinear response measurement current autocorrelations. addition, junction devices tested as hardware platform realizing holonomic quantum computation.

Non-Linear / Non-Commutative Non-Abelian Monopoles
Using recently proposed non-linearly realized supersymmetry in non-Abelian gauge theory corrected to O(α′), we derive the non-linear BPS equations in the background B-field for the U(2) monopoles and instantons. We show that these non-Abelian non-linear BPS equations coincide with the non-commutative anti-self-dual equations via the Seiberg-Witten map.
متن کاملNon-Abelian Josephson effect in spinor Bose- Einstein condensates
We investigate the non-Abelian Josephson effect in F=2 spinor Bose-Einstein condensates with double optical traps. We propose a real physical system which incorporates the non-Abelian Josephson effect and has very different density and spin tunneling characteristics compared with the Abelian case. We calculate the frequencies of the pseudo Goldstone modes in different phases between two traps, ...
متن کاملNon-Abelian Berry Phases and BPS Monopoles
We study a simple quantum mechanical model of a spinning particle moving on a sphere in the presence of a magnetic field. The system has two ground states. As the magnetic field is varied, the ground states mix through a non-Abelian Berry phase. We show that this Berry phase is the path ordered exponential of the smooth SU(2) ’t Hooft-Polyakov monopole. We further show that, by adjusting a pote...
متن کاملNon-abelian Monopoles, Vortices and Confinement
Three closely related issues will be discussed. Magnetic quarks having non-Abelian charges have been found recently to appear as the dominant infrared degrees of freedom in some vacua of softly broken N = 2 supersymmetric QCD with SU(nc) gauge group. Their condensation upon N = 1 perturbation causes confinement and dynamical symmetry breaking. We argue that these magnetic quarks can be naturall...
متن کاملNon-Abelian String Junctions as Confined Monopoles
Various dynamical regimes associated with confined monopoles in the Higgs phase of N = 2 two-flavor QCD are studied. The microscopic model we deal with has the SU(2)×U(1) gauge group, with a Fayet-Iliopoulos term of the U(1) factor, and large and (nearly) degenerate mass terms of the matter hypermultiplets. We present a complete quasiclassical treatment of the BPS sector of this model, includin...
