  1. 1. Topological Photonic Lattices

    University essay from KTH/Tillämpad fysik

    Author : Zesheng Xu; [2022]
    Keywords : Topological photonics; Integrated photonics; Condensed matter physics physics; Optics; Topologisk fotonik; integrerad fotonik; fysik för kondenserad materia; Optik;

    Abstract : Topological Photonics is a rapidly growing field which explores the ideas of topological invariants adapted from condensed matter physics to optical systems. Thanks to integrated photonics platforms, the evolution of light in nanoscale photonic lattices can enable direct measurement of topological properties of the band-structure. READ MORE

  3. 2. Information Flow and Local Observables in Many Body Localized Systems

    University essay from KTH/Fysik

    Author : Daniel Niemi; [2022]
    Keywords : Theoretical physics; many body localization; localization; aubry-andré; aubry-andrei; condensed matter; quantum matter; Teroretisk fysik; mångpartikellokalisering; lokalisering; aubry-andré; aubry-andrei; kondenserad materia; kvantmateria;

    Abstract : Disordered quantum many-body systems exhibiting the many-body localization (MBL) phenomenon evade the fate of thermalization due to the existence of an extensively large set of quasi-local integrals of motion (l-bits). Due to the size of the Hilbert space of many-body systems, it is hard to compute the time evolution of many-body systems generally, which hinders our understanding of the MBL phenomenon. READ MORE

  4. 3. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter

    University essay from KTH/Fysik

    Author : Yashar Honarmandi; [2022]
    Keywords : Theoretical physics; topological quantum matter; parametrized systems; Berry phase; higher Berry curvature; effective field theory; topological action; topological insulators; dimensional hierarchy; Teoretisk fysik; topologisk kvantmateria; parametriserade system; Berryfas; högre Berrykrökning; effektiv fältteori; topologisk verkan; topologiska isolatorer; dimensionshierarki;

    Abstract : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.
