Equilibrio estático
(2015-06-30)
This presentation shows an introduction to the statics, that is an important area of study in the application of mechanical design and force analysis of mechanical components an machines.
Here is an introduction to the ...
Quantum particles that behave as free classical particles
(American Physical Society, 2020)
The existence of nonvanishing Bohm potentials, in the Madelung-Bohm version of the Schrodinger equation, allows for the construction of particular solutions for states of quantum particles interacting with nontrivial ...
Free massive particles with total energy E<mc2 in curved spacetimes
(American Physical Soc, 2002-05-10)
We analyze free elementary particles with a rest mass m and total energy E<mc2 in the Rindler wedge, outside Reissner-Nordstrom black holes and in the spacetime of relativistic (and nonrelativistic) stars, and use ...
Separation versus diffusion in a two species system
(Brazilian Statistical Association, 2015)
We consider a finite number of particles that move in ZZ as independent random walks. The particles are of two species that we call aa and bb. The rightmost aa-particle becomes a bb-particle at constant rate, while the ...
Slot coating flows of non‐colloidal particle suspensions
(John Wiley & Sons Inc, 2017-03)
Slot coating is used in the manufacturing of functional films, which rely on specific particle microstructure to achieve the desired performance. Final structure on the coated film is strongly dependent on the suspension ...
Spinning particles coupled to gravity and the validity of the universality of free fall
(IOP Publishing, 2017-06-08)
Recent experimental work has determined that free falling Rb-87 atoms on Earth, with vertically aligned spins, follow geodesics, thus apparently ruling out spin-gravitation interactions. It is showed that while some spinning ...
Free expansion of attractive and repulsive Bose-Einstein condensed vortex states
(2002-03-01)
A numerical study of the time-dependent Gross-Pitaevskii equation for an axially symmetric trap to obtain insight into the free expansion of vortex states of BEC is presented. As such, the ratio of vortex-core radius to ...
