Magnetic Monopoles, Dyons and Confinement in Quantum Matter

Monopoles and Dyons in Non-Commutative Geometry

Taking advantage of the equivalence between supersymmetric Yang-Mills theory on non-commutative spaces and the field theory limit of D3-branes in the background of NSNS 2-form field, we investigate the static properties of magnetic monopoles and dyons using brane construction techniques. When parallel D3-branes are separated by turning on a Higgs vacuum expectation value, D-strings will stretch...

Anti-gravitating BPS monopoles and dyons

We show that the exact static, i.e. ‘anti-gravitating’, magnetic multi monopole solutions of the Einstein/Maxwell/dilaton-YM/Higgs equations found by Kastor, London, Traschen, and the authors, for arbitrary non-zero dilaton coupling constant a, are equivalent to the string theory BPS magnetic monopole solutions of Harvey and Liu when a = √ 3. For this value of a, the monopole solutions also sol...

Quarks, monopoles and dyons at large N

We study a system of external particles of various charges in N = 4 super Yang-Mills in the large N limit at finite temperature. We demonstrate that at high enough temperature partial or complete screening of the particles can occur. At zero temperature the total electric or magnetic charge cannot be screened, while higher multipole moments of these charges can be screened. The specific case of...

Search for Magnetic Monopoles Trapped in Matter.

There have been many searches for magnetic monopoles in ight, but few for monopoles in matter. We have searched for magnetic monopoles in meteorites, schists, ferromanganese nodules, iron ores and other materials. The detector was a superconducting induction coil connected to a SQUID (Superconducting Quantum Interference Device) with a room temperature bore 15 cm in diameter. We tested a total ...
