     "Noncommutative Quantum Mechanics viewed in term of extended objects"

       Vrijeme:  30. ozujka 2011. (srijeda), 11:00 c.t.

       Mjesto:  Institut Rudjer Boskovic, dvorana I krila

       Sazetak:
We explore the notion of spatial extent and structure, already alluded to in 
earlier literature, within the formulation of quantum mechanics on the 
noncommutative plane. Introducing the notion of average position and its 
measurement, we find two equivalent pictures: a constrained local
description in position containing additional degrees of freedom, and an 
unconstrained nonlocal description in terms of the position without any other 
degree of freedom. The local description is
found to be the most convenient as it manifestly displays additional 
information about structure of quantum states that is more subtly encoded in 
the nonlocal, unconstrained description.
Subsequently, we use this picture to discuss the free particle.
