Quantum Uncertainty in Doubly Special Relativity
The modification of the quantummechanical commutators in a relativistic theory with an invariant length scale (DSR) is identified. Two examples are discussed where a classical behavior is approached in one case when the energy approaches the inverse of the invariant length which appears as a cutoff in the energy and in the second case when the mass is much larger than the inverse of the invaria...
متن کاملDoubly Special Relativity
I give a short non-technical review of the results obtained in recent work on “Doubly Special Relativity”, the relativistic theories in which the rotation/boost transformations between inertial observers are characterized by two observer-independent scales (the familiar velocity scale, c, and a new observer-independent length/momentum scale, naturally identified with the Planck length/momentum)...
متن کاملRelation between quantum κ-Poincaré framework and Doubly Special Relativity
We describe firstly the basic features of quantum κ-Poincaré symmetries with their Hopf algebra structure. The quantum κ-Poincaré framework in any basis relates rigidly the quantum κ-Poincaré algebra with quantum κ-Poincaré group, noncommutative space-time and κ-deformed phase space. Further we present the approach of Doubly Special Relativity (DSR) theories, which introduce (in the version DSR...
متن کاملConformal Generators and Doubly Special Relativity Theories
In this paper, the relation between the modified Lorenz boosts, proposed in the doubly relativity theories and a linear combination of Conformal Group generators in R1,d−1 is investigated. The introduction of a new generator is proposed in order to deform the Conformal Group to achieve the connection conjectured. The new generator is obtained trough a formal dimensional reduction from a free ma...
متن کاملPhase Spaces of Doubly Special Relativity
We show that depending on the direction of deformation of κ-Poincaré algebra (time-like, space-like, or light-like) the associated phase spaces of single particle in Doubly Special Relativity theories have the energy-momentum spaces of the form of de Sitter, anti-de Sitter, and flat space, respectively.
