Continuous Measurements and Feedback Control of a Quantum Harmonic Oscillator

Kvantmekaniken har sedan början av 1900-talet revolutionerat vår försåelse av fysik, framförallt hur ljus och partiklar fungerar och interagerar. En unik egenskap av kvantmekaniken är att den i grunden är en probibalistisk teori, vilket låter oss beskriva system som befinner sig i flera olika tillstånd samtidigt. Detta fenomenet kallas för superposition och är vad som gör kvantmekanik unikt från kQuantum mechanical technologies often relies on the system being cooled to low temperatures. One way to achieve this is with measurement and feedback based cooling. In this thesis measurement and feedback on a quantum harmonic oscillator coupled to a thermal reservoir is considered. The Wiseman-Milburn equation is used with a linear feedback control to find the steady-state solutions for the first

Breakdown of full-size tire to nanoscale particles and their interaction with proteins

Plastpåsar i haven eller avgaser från stora fabriker, det är ofta vad som dyker upp i huvudet när man tänker på miljöföroreningar. Men faktum är att det finns en mindre omtalad bov, som dessutom utgör en enorm andel av dessa miljöföroreningar, nämligen däck. Varje gång en bil rullar över asfalten nöts däcken och släpper ifrån sig små partiklar. Dessa partiklar kan vara både synliga för ögat och såPollution from tire wear particles (TWPs) is a growing concern in environmental and health sciences due to their widespread release and potential toxicity.
