Thermostatistics with an invariant infrared cutoff

Thermostatistics with an invariant infrared cutoff

Abstract Quantum gravitational effects may affect the large scale dynamics of the universe. Phenomenologically, quantum gravitational effect at large distances can be encoded in an extended uncertainty principle that admits a minimal measurable momentum/energy or a maximal length. This maximal lengt...
