Finite -deformed two-particle boost
Andrea Bevilacqua, Jerzy Kowalski-Glikman, Wojciech Wiślicki
In this paper we consider the \k{appa}-deformed boost acting on a two-particles states. Using techniques developed in the case of infinitesimal boost we compute explicit expression…
On the Inevitable Lightness of Vacuum
Laurent Freidel, Jerzy Kowalski-Glikman, Robert G. Leigh +1
In this essay, we present a new understanding of the cosmological constant problem, built upon the realization that the vacuum energy density can be expressed in terms of a phase s…
Quantum particles in non-commutative space-time: an identity crisis
Michele Arzano, Jerzy Kowalski-Glikman
We argue that the notion of identical particles is no longer well defined in quantum systems governed by non-commutative deformations of space-time symmetries. Such models are char…
The Vacuum Energy Density and Gravitational Entropy
Laurent Freidel, Jerzy Kowalski-Glikman, Robert G. Leigh +1
The failure to calculate the vacuum energy is a central problem in theoretical physics. Presumably the problem arises from the insistent use of effective field theory reasoning in…
A tale of two theories of gravity in asymptotically Anti-de Sitter spacetime
Remigiusz Durka, Jerzy Kowalski-Glikman
We consider two BF formulations of the theory of gravity with a negative cosmological constant, of Plebanski and of MacDowell-Mansouri. Both give the standard Einstein equations in…
A group theoretic description of the -Poincaré Hopf algebra
Michele Arzano, Jerzy Kowalski-Glikman
It is well known in the literature that the momentum space associated to the -Poincaré algebra is described by the Lie group . In this letter we show th…
