Fuzzy de Sitter space-times via coherent states quantization

چکیده

A construction of the 2d and 4d fuzzy de Sitter hyperboloids is carried out by using a (vector) coherent state quantization. We get a natural discretization of the dS “time” axis based on the spectrum of Casimir operators of the respective maximal compact subgroups SO(2) and SO(4) of the de Sitter groups SO0(1, 2) and SO0(1, 4). The continuous limit at infinite spins is examined.

Coherent states and quantization of the particle motion on the line, on the circle, on 1 + 1-de Sitter space-time and of more general systems

We describe a quantization procedure based on adapted coherent states. This scheme could reveal itself as an efficient tool for quantizing physical systems for which more traditional methods are uneasy to implement. The procedure is illustrated by simple examples like the wellknown quantization of the particle motion on the line and the yet problematic quantization of the particle motion on the...

Wick ordering for coherent state quantization in 1 + 1 de Sitter space

We show that the coherent state quantization of massive particles in 1+1 de Sitter space exhibits an ordering property: There exist some classical observables A and A∗ such that OA∗pOAq = OA∗pAq p, q ∈ Z, where OA is the quantum observable corresponding to the classical observable A.

دینامیک کوانتومی ذره جرم‌دار روی دوسیتر 3+1

 The phase space which is related to the motion of massive particle on 1+3- De sitter space is a 3-dimensional complex sphere. Our main aim in this study is discribing this movement in the frame quantum mechanics. Transfering from classical mechanic to quantum mechanics is possible by means of coherent states. Thus, after determination of this state, we quantize some of the classical observables.

Comments on Quantum Aspects of Three-Dimensional de Sitter Gravity

We investigate the quantum aspects of three-dimensional gravity with a positive cosmological constant. The reduced phase space of the three-dimensional de Sitter gravity is obtained as the space which consists of the Kerr-de Sitter space-times and their Virasoro deformations. A quantization of the phase space is carried out by the geometric quantization of the coadjoint orbits of the asymptotic...
