    Sammanfattning : Rechargeable batteries, particularly lithium-ion batteries, have rapidly evolved since their introduction and now dominate the market, owing primarily to their high energy and power densities. With growing demand for high-performance batteries in portable electronics and electric vehicles, the need for safe, efficient, and reliable batteries is crucial. LÄS MER

  3. 2. Stability and Mobility of Localized and Extended Excitations in Nonlinear Schrödinger Models

    Författare :Michael Öster; Magnus Johansson; Sergej Flach; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-linear dynamics; chaos; Icke-linjär dynamik; kaos;

    Sammanfattning : This thesis is mainly concerned with the properties of some discrete nonlinear Schrödinger equations. These naturally arise in many different physical contexts as the limiting form of general dynamical lattice equations that incorporate nonlinearity and coupling. LÄS MER
