1. 1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

   University essay from KTH/Tillämpad fysik

   Author : Emrah Tortumlu; [2023]
   Keywords : Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

   Abstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

5. 4. How to Rise from Ashes : A Comprehensive Guide to Finally Understand Canonical Quantization and Build Quantum Mechanics from Scratch

   University essay from Uppsala universitet/Materialteori; Uppsala universitet/Avdelningen för teoretisk filosofi

   Author : Karl Herlin; [2022]
   Keywords : Quantum mechanics; History of quantum mechanics; Canonical Quantization; double-slit experiment; The Photoelectric Effect; Compton Scattering; Matter Waves; Bohr’s Atomic Model; Old Quantum Theory; Heisenberg-Born-Jordan Matrix Mechanics; Schrodinger’s Quantum Wave Mechanics; equations of motion;

   Abstract : In this review essay, we account for the historical development of canonical quantization. By a detailed review of The Ultraviolet Catastrophe, The Photoelectric Effect, Compton Scattering, Matter Waves and Bohr's Atomic Model we learn about Old Quantum Theory. READ MORE

6. 5. Investigating the use of Semiconductor Nanowires for Neural Networks

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Alfredo Serafini; [2022]
   Keywords : FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

   Abstract : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. READ MORE
