  2. 1. Emergent spacetime from simple field theories

    Author : Julius Engelsöy; Bo Sundborg; Sumit R. Das; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AdS CFT; thermalization; quench; large N singlet models; emergent spacetime; fysik; Physics;

    Abstract : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. READ MORE

  4. 2. Linear response theory: from black holes to Weyl systems and back

    Author : Jorge Laraña Aragón; Bo Sundborg; Lárus Thorlacius; Emil J. Bergholtz; Ulf Gran; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Linear response; Black holes; Thermalization; Holography; Weyl systems; Non-Hermitian systems; Theoretical Physics; teoretisk fysik;

    Abstract : Linear response theory is a powerful calculation tool in quantum field theory. We apply this framework to a variety of models originating from distinct areas in theoretical physics and for different reasons. READ MORE

  5. 3. Linear response theory : from black hole thermalization to Weyl semimetals

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. READ MORE

  6. 4. Quenched coupling and thermal behavior in the O(N) vector model

    Author : Julius Engelsöy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a thermal state in the boundary CFT is dual to a black hole in the bulk spacetime, thermalization in the CFT is dual to black hole formation in AdS. READ MORE

  7. 5. The Struggles of Light Bound in Matter : Modelling Optical Excitations in Nanostructures

    Author : Alex Arash Sand Kalaee; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; open quantum systems; nanooptics; non-equilibrium statistical mechanics; quantum thermodynamics; Fysicumarkivet A:2021:Kalaee;

    Abstract : This thesis addresses three different topics on the interaction between light and matter in open quantum systems. The first topic concerns two-dimensional spectroscopy and the spectral contributions from different nonlinear action signals with a focus on how to differentiate between them. READ MORE
