    • Anomalous dynamics and equilibration in the classical Heisenberg chain 

      Mcroberts, Adam J.; Bilitewski, Thomas; Haque, Masudul; Moessner, Roderich (2021-08-26)
      The search for departures from standard hydrodynamics in many-body systems has yielded a number of promising leads, especially in low dimension. Here we study one of the simplest classical interacting lattice models, the ...

    • Disordered flat bands on the kagome lattice 

      Bilitewski, Thomas; Moessner, Roderich (2018-09-27)
      We study two models of correlated bond- and site-disorder on the kagome lattice considering both translationally invariant and completely disordered systems. The models are shown to exhibit a perfectly at ground state band ...

    • Dynamics and energy landscape of the jammed spin-liquid 

      Bilitewski, Thomas; Zhitomirsky, Mike E.; Moessner, Roderich (2018-11-20)
      We study the low temperature static and dynamical properties of the classical bond-disordered antiferromagnetic Heisenberg model on the kagome lattice. This model has recently been shown to host a new type of spin liquid ...

    • Exotic superconductivity through bosons in a dynamical cluster approximation 

      Bilitewski, Thomas; Pollet, Lode (2015-08-07)
      We study the instabilities towards (exotic) superconductivity of mixtures of spin-1/2 fermions coupled to scalar bosons on a two-dimensional square lattice with the Dynamical-Cluster-Approximation (DCA) using a numerically ...

    • Inverted hysteresis and negative remanence in a homogeneous antiferromagnet 

      Opherden, L.; Bilitewski, T.; Hornung, J.; Herrmannsdörfer, T.; Samartzis, A.; Islam, A. T. M. N.; Anand, V. K.; Lake, B.; Moessner, R.; Wosnitza, J. (2018-02-13)
      Magnetic remanence -- found in bar magnets or magnetic storage devices -- is probably the oldest and most ubiquitous phenomenon underpinning technological applications of magnetism. It is a macroscopic non-equilibrium ...

    • Jammed spin liquid in the bond-disordered kagome Heisenberg antiferromagnet 

      Bilitewski, Thomas; Zhitomirsky, Mike E.; Moessner, Roderich (2017-06-13)
      We study a class of continuous spin models with bond disorder including the kagome Heisenberg antiferromagnet. For weak disorder strength, we find discrete ground states whose number grows exponentially with system size. ...
