Transform-based quantum potential reconstruction from sparse spectral data: generalized Bertlmann-Martin moment inequalities
Inverse quantum problems ask whether a central potential V(r) can be reconstructed from limited spectral information under explicit modeling assumptions. This dissertation develops and validates a reproducible, transform-based framework for reconstructing ground-state radial densities rho(r) = …

Chaos and Momentum Diffusion of the Classical and Quantum Kicked Rotor
The de Broglie-Bohm (BB) approach to quantum mechanics gives trajectories similar to classical trajectories except that they are also determined by a quantum potential. The quantum potential is a "fictitious potential" in the sense that it is part of the quantum kinetic energy. We use quantum …

Enhancement of Monte Carlo Simulations on Three-Dimensional Nanoscale Semiconductor Devices
… on the position of the carrier. This way, quantum effects are explicitly taken into consideration in carrier transport. The approach has been simulated for different sizes of silicon nanowires (SiNWs). When high bias applies in the longitudinal and the transverse direction of the channel …

Theoretical methods for the study of quantum dynamics
… theoretical methods for the computation of quantum dynamical quantities are formulated, implemented, and applied, in the overall context of overcoming the exponential scaling property of quantum mechanics. The convergence of the approximate forward-backward semiclassical dynamics (FBSD) …

On the Generation of Entanglement in Ytterbium Clock Atoms and a Novel Interpretation of the Madelung Fluid Theory of Quantum Mechanics
… a novel interpretation of the Madelung Theory of Quantum Mechanics, namely that of a particle-fluid decomposition and it's consequences. In more detail, in one experiment, we demonstrate near-unitary squeezing of the collective spin state of ~10³ atoms in an optical lattice clock atom wiht a …
