Imprints of microcausality violation on the cosmic microwave background
Archil Kobakhidze
We consider a modification of the Heisenberg algebra with the non-vanishing commutator of scalar field operators. We then identify the scalar field with the second quantized inflat…
CP violation and gravity as the weakest force
Archil Kobakhidze
We argue that CP violation has rather dramatic impact on the "gravity as the weakest force" conjecture. Namely we find that new ultraviolet scale must be , wher…
Dyons with hidden electric charges and the long-range magnetic force
Archil Kobakhidze
When gauge U(1) is spontaneously broken, associated electric charges are screened. We argue that corresponding magnetic charges, on the contrary, produce long-range force. Some int…
(De)quantization of black hole charges
Archil Kobakhidze, Bruce H. J. McKellar
We argue that magnetic and electric charges of the Reissner-Nordstrom black hole are quantized in CP conserving theories. Dequantization phenomenon occurs when CP is broken either…
