Current Research

Presently my research interests are focused on some theoretical and phenomenological questions of the Planck-length deformed quantum theory. Such a theory is non-local, violates the Lorentz symmetry and suggests a number of interesting features in the UV regime. One of the interesting questions is related to the radiative corrections. On the one hand, for this sort of theories, Lorentz violation might serve as a UV regulator 1; on the other hand, it is well known that the one loop corrections in theories with (Lorentz violating) modified dispersion relations show up an unacceptably large effects : 1, 2, 3, 4. One more interesting topic is the possible detection of the Planck length effects via the electromagnetic field in Lab or cosmological observations.
