1. Generalizations of the Mandelstam-Tamm Quantum Speed Limit
University essay from Stockholms universitet/FysikumAbstract : Quantum speed limits are lower bounds on the evolution time for quantum systems. In this thesis, we consider closed quantum systems. We investigate how different principal bundles offers a geometrical method for obtaining generalizations of the Mandelstam-Tamm quantum speed limit for mixed states. READ MORE

2. Investigation of Resistive Random Access Memory for 1T1R Nanowire Array Integration
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : As modern electronics have started to reach its physical scaling limits, novel architectures and physics is needed to meet future demands. Oxide-based Resistive Random Access Memory (RRAM) is a new emerging technology that uses filament formation and rupture in thin oxides to generate resistive switching. READ MORE

3. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

4. Quantum Speed Limits of Spin Chain Dynamics : Applying Quantum Speed Limits to Spin Chains used as Quantum Channels
University essay from Uppsala universitet/Teoretisk fysikAbstract : Quantum computers, like classical ones, need to be capable of sending informa-tion between different parts of the computer. Spin chains are one viable method of sending qubits while preserving the superposition and entanglement of a state. READ MORE
