Multidimensional spectroscopy of correlated systems in the Floquet formalism

Från det att kvantmekaniken utvecklades under den större delen av 1900-talet har en mängd nya områden introducerats inom fysikens värld. Bland dessa finner vi fasta tillståndets fysik, som beskriver hur de allra minsta partiklarna interagerar med vår värld. Framförallt vill man beskriva hur partiklar beter sig i olika material, samt reagerar på diverse externa krafter. Detta är till exempel en oerMulti-dimensional spectroscopy is a technique used by scientists to capture ultra-fast quantum effects. In particular, it uses several different frequencies to investigate nonlinear responses. Here we use this technique and apply it on a system of 2 spin-1/2 particles having some magnetic moment, and investigate the behavior of the probability density for a certain spin-state as well as the spin e

The study assesses whether the motivation behind the reform has taken

Machine Learning and AI methods for Design Of Experiments in the study of electrical contact

The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the

Personalizing the Path to Relief - A Statistical Analysis of Treating Chronic Migraine with CGRP mAbs

Migrän är en neurologisk sjukdom som drabbar ungefär 15 procent av världens befolkning och har stor påverkan på individens vardag. Sjukdomen karaktäriseras av attacker som ger kraftig huvudvärk, tillsammans med illamående och känslighet mot ljud och ljus. Även om det är attackerna som kännetecknar migrän, upplever många även symtom, som trötthet och ångest, mellan anfallen. Kvinnor är överrepresenMigraine is a highly debilitating neurological disorder that affects approximately 15% of the global population. It is most commonly associated with severe headaches that can leave sufferers bedridden, but its impact extends beyond the attacks themselves. The disease presents in various forms, ranging from sporadic attacks to regular ones following the female hormone cycle, and chronic migraine, w
