Geometric phases in quantum systems of pure and mixed state
... The purpose of this work is to introduce the concept of geometric phase and to describe different variants for quantum systems which are in a pure or mixed state. This work is divided into 5 parts. A preliminary section is intended to prepare the reader for the mathematical concepts and reasoning im ...

The Double Rotation as Invariant of Motion in Quantum Mechanics
... rotation paradigm (considered further). Where to find second half of rotator? He/it moves in some other space? But spaces are not at all in principle. Let us reconstruct Motion in order to find missing half. To do this we must consider reflection, i.e., one more versor in geometric algebra. In spati ...

As before, we can obtain one ground state in Λ simply by considering the Hamiltonian HΛ with empty boundary conditions. As stated in Theorem 1, this Hamiltonian has a non-degenerate ...
