A Novel Approach to Noncommutativity in Planar Quantum Mechanics

نویسنده

  • Rabin Banerjee
چکیده

Noncommutative algebra in planar quantum mechanics is shown to follow from ’t Hooft’s recent analysis on dissipation and quantization. The noncommutativity in the coordinates or in the momenta of a charged particle in a magnetic field with an oscillator potential are shown as dual descriptions of the same phenomenon. Finally, noncommutativity in a fluid dynamical model, analogous to the lowest Landau level problem, is discussed.

Dissipation and Noncommutativity in Planar Quantum Mechanics

Noncommutative algebra in planar quantum mechanics is shown to follow from ’t Hooft’s recent analysis on dissipation and quantization.

Finally, noncommutativity in a fluid dynamical model, analogous to the lowest ...

Wavepackets and Duality in Noncommutative Planar Quantum Mechanics

Effects of noncommutativity are investigated in planar quantum mechanics in the coordinate representation. Generally these issues are addressed by converting to the momentum space. In the first part of the work we show noncommutative effects in a Gaussian wavepacket through the broadening of its width. We also rederive results on ∗-product of Gaussian wavepackets. In the second part, we constru...

Extended Space Duality in the Noncommutative Plane

Non-Commutative (NC) effects in planar quantum mechanics are investigated. We have constructed a Master model for a noncommutative harmonic oscillator by embedding it in an extended space, following the Batalin-Tyutin [5] prescription. Different gauge choices lead to distinct NC structures, such as NC coordinates, NC momenta or noncommutativity of a more general kind. In the present framework, ...

Noncommutative Quantum Mechanics

We consider Feynman’s path integral approach to quantum mechanics with a noncommutativity in position and momentum sectors of the phase space. We show that a quantum-mechanical system with this kind of noncommutativity is equivalent to the another one with usual commutative coordinates and momenta. We found connection between quadratic classical Hamiltonians, as well as Lagrangians, in their co...

Adelic strings and noncommutativity

We consider adelic approach to strings and spatial noncommutativity. Path integral method to string amplitudes is emphasized. Uncertainties in spatial measurements in quantum gravity are related to noncommutativity between coordinates. p-Adic and adelic Moyal products are introduced. In particular, p-adic and adelic counterparts of some real noncommutative scalar solitons are constructed.
