    • 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 ...

    • Classical many-body chaos with and without quasiparticles 

      Bilitewski, Thomas; Bhattacharjee, Subhro; Moessner, Roderich (2020-11-09)
      We study correlations, transport and chaos in a Heisenberg magnet as a classical model many-body system. By varying temperature and dimensionality, we can tune between settings with and without symmetry breaking and ...

    • 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 ...

    • 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. ...

    • Long-lived solitons and their signatures in the classical Heisenberg chain 

      McRoberts, Adam J.; Bilitewski, Thomas; Haque, Masudul; Moessner, Roderich (2022-07-18)

    • Temperature dependence of butterfly effect in a classical many-body System 

      Bilitewski, Thomas; Bhattacharjee, Subhro; Moessner, Roderich (2018-08-06)
      We study the chaotic dynamics in a classical many-body system of interacting spins on the kagome lattice. We characterise many-body chaos via the butter y effect as captured by an appropriate out-of-time-ordered correlator. ...
