چکیده

Given a simple Lie algebra g, we consider the orbits in g * which are of R-matrix type, i.e., which possess a Poisson pencil generated by the Kirillov-Kostant-Souriau bracket and the so-called R-matrix bracket. We call an algebra quantizing the latter bracket a quantum orbit of R-matrix type. We describe some orbits of this type explicitly and we construct a quantization of the whole Poisson pencil on these orbits in a similar way. The notions of q-deformed Lie brackets, braided coadjoint vector fields and tangent vector fields are discussed as well.

Poisson homology of R - matrix type orbits I : example of computation Alexei

The Poisson homology was introduced in [1][9]. There are at least two reasons to study them. The first argument is that one can compute Hochschild complex for a deformed algebra of smooth functions using Poisson homology as the second term in appropriate spectral sequence. The next argument was established not so long time ago. There is a connection between canonical (Poisson homology) complex ...

Non-Local Properties of Multi-Particle Density Matrices

quantum mechanics, quantum information, quantum non-locality, quantum entanglement As far as entanglement is concerned, two density matrices of n particles are equivalent if they are on the same orbit of the group of local unitary transformations, U (d1) × ??? × U (dn) (where the Hilbert space of particle r has dimension dr). We show that for n greater than or equal to two, the number of indepe...

Poisson Homology of r-Matrix Type Orbits I: Example of Computation

In this paper we consider the Poisson algebraic structure associated with a classical r-matrix, i.e. with a solution of the modified classical Yang–Baxter equation. In Section 1 we recall the concept and basic facts of the r-matrix type Poisson orbits. Then we describe the r-matrix Poisson pencil (i.e the pair of compatible Poisson structures) of rank 1 or CPn-type orbits of SL(n,C). Here we ca...

GENERALIZED JOINT HIGHER-RANK NUMERICAL RANGE

The rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. For noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. In this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, Generaliz...

Deformation quantization and quantum coadjoint orbits of SL(2,R)

In this article we describe the coadjoint orbits of SL(2,R). After choosing polarizations for each orbits, we pointed out the corresponding quantum coadjoint orbits and therefore unitary representations of SL(2,R) via deformation quantization.
