Exact solvability of potentials with spatially dependent effective masses
(2000-10-02)
We discuss the relationship between exact solvability of the Schroedinger equation, due to a spatially dependent mass, and the ordering ambiguity. Some examples show that, even in this case, one can find exact solutions. ...

Fisher information and quantum systems with position-dependent effective mass
(Elsevier Science, 2000-03)
We show that effective masses in nonrelativistic quantum mechanics arise in a natural fashion from the Frieden and Soffer's Principle of Extremal Information (EPI) when the mean values of operators involving the momentum ...
Influence of liquid viscosity and gas superficial velocity on effective mass transfer area in packed columns

QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons
(Elsevier B.V., 2015-05-11)
Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is ...
The Effect of Magnetic Activity on Low-Mass Stars in Eclipsing Binaries
(2010)
In recent years, analyses of eclipsing binary systems have unveiled differences between the observed fundamental properties of low-mass stars and those predicted by stellar structure models. Particularly, radius and effective ...
