Unified Theory of Gravity and Electromagnetism: Classical and Quantum Aspects


  • Avik Dubey Ramkrishna Mahato Government Engineering College,Purulia, West Bengal India



A unified classical theory of gravity and electromagnetism with a torsion vector  0, proposed by S N Bose in 1952, is introduced. In this theory, the torsion vector acts as a magnetic current and it is shown that (i) the electromagnetism is invariant under continuous Heaviside–Larmor transformations and (ii) the electric and magnetic charges are topologically quantised, satisfying the Dirac quantisation condition, without implying any Dirac string provided is curl-less.
