Blackbody radiation inκ-Minkowski spacetime

Abstract: We have computed the black body radiation spectra in κ−Minkowski space-time, using the quantum mechanical picture of massless scalar particles as well as effective quantum field theory picture. The black body radiation depends on how the field theory (and thus how the κ−Poincaré algebra) handles the ordering effect of the noncommutative space-time. In addition, there exists a natural momentum cut-off of the order κ, beyond which a new real mode takes its shape from a complex mode and the old real mode flows ou… Show more

“…El problema de la radiación de cuerpo negro también ha sido considerado en un espacio-tiempo de (n+1) dimensional por Nozari y Anvari (2012); Husain et al (2013a) y por Bosso y Vega (2022) donde las dimensiones extras son consideradas a través el principio de incertidumbre generalizado, donde los términos de corrección a la ley de Stefan-Boltzmann contienen solo las potencias pares de la temperatura. El problema de la radiación de cuerpo negro en un espacio-tiempo de κ-Minkowski y en un espacio-tiempo de AdS 5 × S 5 se estudió en Kim et al (2007) y también en . También se ha estudiado el problema de radiación de cuerpo negro en teorías de cuantización polimérica Husain et al (2013b) y en teorías de estadísticas generalizadas Moradpour et al (2022).…”

“…The deformed Poincaré algebra allows two invariant parameters and is noted to be related with doubly special relativity [9]. However, it is realized that the field theoretical approach in this spacetime is afflicted with difficulties, such as violation of causality [10], instability of vacuum structure [11] and energy momentum non-conservation in interacting field theory [12].…”
