Mimetic Dark Matter from Inflation
Ali H. Chamseddine, Viatcheslav Mukhanov
We investigate the coupling of mimetic dark matter to the Gauss-Bonnet topological term in addition to the Einstein-Hilbert action. We demonstrate that such interactions can natura…
Anomalous scaling in shell model turbulence
James Creswell, Viatcheslav Mukhanov, Yaron Oz
Shell model turbulence is a simplified mathematical framework that captures essential features of incompressible fluid turbulence such as the energy cascade, intermittency and anom…
Mimetic Inflation and Self-reproduction
Ali H. Chamseddine, Mariam Khaldieh, Viatcheslav Mukhanov
It is shown how self-reproduction can be easily avoided in the inflationary universe, even when inflation starts at Planck scales. This is achieved by a simple coupling of the infl…
About the Coleman Instantons in D Dimensions
Viatcheslav Mukhanov, Alexander Sorin
We identify an infinite class of unbounded potentials for which the Coleman instantons do not exist in D-dimensional spacetime. For such potentials, the decay of a false vacuum is…
Discrete Gravity
Ali H. Chamseddine, Viatcheslav Mukhanov
We assume that the points in volumes smaller than an elementary volume (which may have a Planck size) are indistinguishable in any physical experiment. This naturally leads to a pi…
Instantons with Quantum Core
Viatcheslav Mukhanov, Alexander Sorin
We consider new instantons that appear as a result of accounting for quantum fluctuations. These fluctuations naturally regularize the O(4) singular solutions abandoned in Coleman'…
