Quantum scale invariance on the lattice
Mikhail E. Shaposhnikov, Igor I. Tkachev
We propose a scheme leading to a non-perturbative definition of lattice field theories which are scale-invariant on the quantum level. A key idea of the construction is the replace…
Inflation
I. I. Tkachev
Inflationary cosmology is reviewed. Particular attention is given to processes of creation.
Ultra High Energy Cosmic Rays and Inflation Relics
Vadim A. Kuzmin, Igor I. Tkachev
There are two processes of matter creation after inflation that may be relevant to the resolution of the puzzle of cosmic rays observed with energies beyond GZK cut-off: 1) gravita…
Ultra High Energy Cosmic Rays and Inflation
I. I. Tkachev
Two processes of matter creation after inflation: 1) gravitational creation of superheavy (quasi)stable particles, and 2) non-thermal phase transitions leading to formation of topo…
