Fe b 20 09 Position - dependent noncommutativety in quantum mechanics

چکیده
The model of the position-dependent noncommutativety in quantum mechanics is proposed. We start with a given commutation relations between the operators of coordinatesˆx i , ˆ x j = ω ij (ˆ x), and construct the complete algebra of commutation relations, including the operators of mo-menta. The constructed algebra is a deformation of a standard Heisenberg algebra and obey the Jacobi identity. The key point of our construction is a proposed first-order Lagrangian, which after quantization reproduces the desired commutation relations. Also we study the possibility to localize the noncommutativety.

A new procedure of the linear position measurement which allows to obtain sensitivity better than the Standard Quantum Limit and close to the Energetic Quantum Limit is proposed and analyzed in details. Proposed method is based on the principles of stroboscopic quantum measurement and variation quantum measurement and allows to avoid main disadvantages of both these procedures. This method can ...
متن کاملv 1 2 0 Fe b 20 03 Lagrangian Aspects of Quantum Dynamics on a Noncommutative Space ∗
In order to evaluate the Feynman path integral in noncommutative quantum mechanics, we consider properties of a Lagrangian related to a quadratic Hamiltonian with noncommutative spatial coordinates. A quantum-mechanical system with noncommutative coordinates is equivalent to another one with commutative coordinates. We found connection between quadratic classical Lagrangians of these two system...

We uncover a new type of unitary operation for quantum mechanics on the half-line which yields a transformation to “Hyperbolic phase space” (η, pη). We show that this new unitary change of basis from the position x on the half line to the Hyperbolic momentum pη, transforms the wavefunction via a Mellin transform on to the critial line s = 1/2 − ipη. We utilise this new transform to find quantum...
متن کاملStructure-Activity Relationship of Imidazobenzodiazepines, an AM1 Semi-Empirical Quantum Mechanics Study
Conformations and electronic properties of a series of imidazobenzodiazepines are investigated by AM1 semi-empirical quantum mechanics method. It is shown that substitution of Cl in position 7 instead of 8, changes the geometry of the seven membered lactam ring; this may put the N5 nitrogen in a better positon to act as a hydrogen bond acceptor, and the phenyl ring in position 6 is probably...
