Fractionally charged extended objects and superselection rules
Narendra Sahu, Urjit A. Yajnik
Topological objects resulting from symmetry breakdown may be either stable or metastable depending on the pattern of symmetry breaking. However, if they trap zero-energy modes of f…
Quantum Mechanical Spectra of Charged Black Holes
Saurya Das, P. Ramadevi, U. A. Yajnik +1
It has been argued by several authors, using different formalisms, that the quantum mechanical spectrum of black hole horizon area is discrete and uniformly spaced. Recently it was…
Transient domain walls and lepton asymmetry in the Left-Right symmetric model
J. M. Cline, U. A. Yajnik, S. N. Nayak +1
It is shown that the dynamics of domain walls in Left-Right symmetric models, separating respective regions of unbroken SU(2)_L and SU(2)_R in the early universe, can give rise to…
Black hole area quantization
Saurya Das, P. Ramadevi, U. A. Yajnik
It has been argued by several authors that the quantum mechanical spectrum of black hole horizon area must be discrete. This has been confirmed in different formalisms, using diffe…
