Squeezed Fourier Meets Toeplitz Algebras
Bogdan Mielnik, Jesús Fuentes
We look for new steps on the dynamical operations that may squeeze simultaneously some families of quantum states, independently of their initial shape, induced by softly acting ex…
Spectra and Bifurcations
P. Grochowski, W. Kaniowski, B. Mielnik
The concept of spectrum for a class of non-linear wave equations is studied. Instead of looking for stability, the key to the spectral structure is found in the instability phenome…
The Puzzle of Empty Bottle in Quantum Theory
Bogdan Mielnik
We discuss an extremely simple effect of 'shadowing' where the very existence of the measuring apparatus deforms the evolution of quantum states even if the measurement is never pr…
Squeezing: from numerical to conceptual problems
B. Mielnik, J. Fuentes
In the studies of the squeezing it is customary to focus more attention on the particular squeezed states and their evolution than on the dynamical operations that could squeeze si…
Quantum Operations: technical or fundamental challenge?
Bogdan Mielnik
A class of unitary operations generated by idealized, semiclassical fields is studied. The operations implemented by sharp potential kicks are revisited and the possibility of perf…
Convex Geometry: a travel to the limits of our knowledge
Bogdan Mielnik
Our knowledge and ignorance concerning the geometry of quantum states are discussed.
