Control of a Quantum Particle in a Moving Potential Well
The control is the potential well absolute position. For two kinds of potential shape (periodic and box), we propose approximated solutions to the stead-state motion planing problem: steering in finite time the particle from an initial well position to a final well position, the initial and final particle energies being identical. This problem is a quantum analogue of the water tank problem, wh...
متن کاملNOTE show low levels of traversal across
Background: is generally considered safe, and is Saccharomyces cerevisiae involved in the production of many types of foods and dietary supplements. However, some isolates, which are genetically related to strains used in brewing and baking, have shown virulent traits, being able to produce infections in humans, mainly in immunodeficient patients. This can lead to systemic infections in humans....
متن کاملtraversal time problem ∗
The theory of weak measurement, proposed by Aharonov and coworkers, has been applied by Steinberg to the long-discussed traversal time problem. The uncertainty and ambiguity that characterize this concept from the perspective of von Neumann measurement theory apparently vanish, and joint probabilities and conditional averages become meaningful concepts. We express the Larmor clock and some othe...
متن کاملA Convergent Iterative Solution of the Quantum Double-well Potential∗
We present a new convergent iterative solution for the two lowest quantum wave functions ψev and ψod of the Hamiltonian with a quartic double well potential V in one dimension. By starting from a trial function, which is by itself the exact lowest even or odd eigenstate of a different Hamiltonian with a modified potential V + δV , we construct the Green’s function for the modified potential. Th...
متن کاملRelativistic Time-of-Arrival and Traversal Time
We compute in a relativistic way the time-of-arrival and the traversal time through a region of a free particle with spin 1 2 . We do this by applying the relativistic extension of the Event-Enhanced Quantum Theory which we have presented in a previous paper. We find a very good coincidence of the results of our formalism and the results obtained by using classical relativistic mechanics. PACS ...
