  1. 1. Ensemble Green's Function Theory for Interacting Electrons with Degenerate Ground States

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Erik Linnér; [2019]
    Keywords : Green s function; Degeneracy; Density matrix; Ensemble; GW; Zero-temperature; Finite-temperature; Hubbard model; Two-dimensional harmonic oscillator; Ising model; Hydrogen-like model; Physics and Astronomy;

    Abstract : An ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. READ MORE

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Klara Kållberg; [2019]
    Keywords : värmebölja; urbant värmeöfenomen; klimatanpassning; värmetålighet; albedo; arkitekttävling;

    Abstract : I samband med att klimatet förändras kommer både värmeböljor och det urbana värmeöfenomenet, enligt SMHI, bli allt vanligare i svenska städer. Värmen kommer dessutom att bli kraftigare och mer varaktig vilket ställer krav på att genomföra klimatanpassade åtgärder för att minska de negativa konsekvenserna som kan uppstå i staden och för stadens invånare.
