Quantum fluctuations and thermodynamic processes in the presence of closed... by Tsunefumi Tanaka
... A closed timelike curve (CTC) is a closed loop in spacetime whose tangent vector is everywhere timelike. A spacetime which contains CTC’s will allow time travel. One of these spacetimes is Grant space. It can be constructed from Minkowski space by im posing periodic boundary conditions in spatial d ...

We will start in Chapter 1 by some recalls about bounded operators in Hilbert spaces and their spectra, as well as important properties of projections and positive operators, which will play a crucial role in the main proofs. Chapter 2 will be devoted to the proof of the spectral theorem for bounded ...

In figure 2 the quantum capture time is evaluated by using the bulk phonon model (1) as well as by using the DC phonon model from the appendix. One sees that in the case of electrons the results of the DC phonon model exceed the results of the bu ...
