Electromagnetic superconductivity of vacuum induced by strong magnetic field: Numerical evidence in lattice gauge theory

Using numerical simulations of quenched SU (2) gauge theory we demonstrate that an external magnetic field leads to spontaneous generation of quark condensates with quantum numbers of electrically charged I mesons if the strength of the magnetic field exceeds the critical value e B c = 0.927 (77) Ge...

Beschreibung
Zusammenfassung:Using numerical simulations of quenched SU (2) gauge theory we demonstrate that an external magnetic field leads to spontaneous generation of quark condensates with quantum numbers of electrically charged I mesons if the strength of the magnetic field exceeds the critical value e B c = 0.927 (77) GeV 2 or B c = (1.56 +/- 0.13) a 10 16 Tesla . The condensation of the charged I mesons in strong magnetic field is a key feature of the magnetic-field-induced electromagnetic superconductivity of the vacuum.
