Open Strings in Constant Electric and Magnetic Fields
Various properties of open strings in external constant E.M. fields are reviewed. In particular, the charged-particle pair production rate in an external electric field is evaluated, and shown to reduce to Schwinger’s formula in the limit of low-intensity fields. Open strings in external magnetic fields are shown to undergo an infinite number of phase transitions as the strenght of the field in...

متن کاملTheory of Quantum Well Excitons in Electric and Magnetic Fields
The effects of external electric and magnetic fields on excitons in GaAsIAlGaAs quantum wells have been calculated in the effective mass approximation. Recent experiments by Viiia et al. which identify exciton couplings induced by an electric field are satisfactorily explained by the effects of valence band mixing. The properties of magneto-excitons in quantum wells are also found to be charact...
متن کاملEnhanced hyperfine magnetic fields for face-centered tetragonal Fe(110) ultrathin films on vicinal Pd(110)
The structure and hyperfine magnetic properties of epitaxial Fe ultrathin films on a vicinal Pds110d surface have been investigated by means of low-energy electron diffraction sLEEDd, reflection high-energy electron diffraction sRHEEDd and Fe conversion electron Mössbauer spectroscopy sCEMSd. LEED and RHEED provide evidence for initial pseudomorphic film growth. The RHEED determination of the i...
متن کاملElectric and Magnetic Fields
California Electric and Magnetic Fields Program A Project of the California Department of Health Services and the Public Health Institute INTRODUCTION Our daily use of electricity is taken for granted, yet scientific and public concern has arisen about possible health effects from electric and magnetic fields (EMF) that are created by the use of electricity. Because of this concern, the Califor...
