  1. 1. Anomaly and Topology : On the axial anomaly, domain wall dynamics, and local topological markers in quantum matter

    Author : Julia D. Hannukainen; Jens H. Bardarson; Adolfo G. Grushin; Teemu Ojanen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chiral anomaly; axial anomaly; topological phases of matter; Weyl semimetals; magnetic domain walls; local topological markers;

    Abstract : Chiral anomalies and topological phases of matter form the basis of the research presented in this dissertation. The chiral anomaly is considered both in the context of magnetic Weyl semimetals and in the context of non-Hermitian Dirac actions. READ MORE

  2. 2. Finite-time  non-equilibrium thermodynamics of a colloidal particle

    Author : Sreekanth K. Manikandan; Supriya Krishnamurthy; Jens H. Bardarson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : In this thesis we have thermodynamically characterized finite time processes performed on a colloidal particle, kept in contact with thermal reservoir(s). Thermodynamic processes are implemented on the colloidal particle by systematically changing the confining potential in a time dependent way, according to an external driving protocol or by controlling the environmental conditions over a finite duration.

  3. 3. Homology and machine learning for materials informatics

    Author : Bart Olsthoorn; Jens H. Bardarson; Alexander V. Balatsky; O. Anatole von Lilienfeld; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; Teoretisk fysik;

    Abstract : Materials informatics is the field of study where materials science is combined with modern data science. This data-driven approach is powered by the growing availability of computational power and storage capability. READ MORE

  4. 4. Entanglement spectrum and the bulk polarization

    Author : Carlos Ortega-Taberner; Maria Hermanns; Jens Bardarson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : In this Licentiate thesis we give a brief review on the topics of topologicalinsulator and superconductor phases, the modern theory of polarization andthe entanglement spectrum, with a focus on one- and two-dimensional systems.In the context of symmetry protected topological systems the bulk polarizationcan be a topological invariant which characterizes the topological phase.
