These are notes on the square root of $4\times4$ identity matrix and associated quantum fields of spin one half. The method is illustrated by constructing a new mass dimension one bosonic field. The locality constraint for the field leads naturally to maximum parity violation. The degrees of freedom carried by the new bosons are different from any massive boson previously encountered and coincide with those carried by spin one half fermions. We thus provide a quantum field suspected to exist by… Expand

In 2005, Dharam Ahluwalia and Daniel Grumiller reported an unexpected theoretical discovery of mass dimension one fermions. These are an entirely new class of spin one half particles, and because of… Expand

The new quantum mechanics, when applied to the problem of the structure of the atom with point-charge electrons, does not give results in agreement with experiment. The discrepancies consist of… Expand
