The Kibble-Zurek mechanism at exceptional points
Balázs Dóra, Markus Heyl, Roderich Moessner
Exceptional points (EPs) are ubiquitous in non-hermitian systems, and represent the complex counterpart of critical points. By driving a system through a critical point at finite r…
Logarithmic spreading of out-of-time-ordered correlators without many-body localization
Adam Smith, Johannes Knolle, Roderich Moessner +1
Out-of-time-ordered correlators (OTOCs) describe information scrambling under unitary time evolution, and provide a useful probe of the emergence of quantum chaos. Here we calculat…
Spin Hall effect in 2D metallic delafossite PtCoO and vicinity topology
Sota Kitamura, Hidetomo Usui, Robert-Jan Slager +9
The two-dimensional (2D) metal PtCoO is renowned for the lowest room temperature resistivity among all oxides, close to that of the top two materials Ag and Cu. In addition, we…
Dynamics and energy landscape of the jammed spin-liquid
Thomas Bilitewski, Mike E. Zhitomirsky, Roderich Moessner
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…
Quantum spin liquid at finite temperature: proximate dynamics and persistent typicality
I. Rousochatzakis, S. Kourtis, J. Knolle +2
Quantum spin liquids are long-range entangled states of matter with emergent gauge fields and fractionalized excitations. While candidate materials, such as the Kitaev honeycomb ru…
Spectrum of itinerant fractional excitations in quantum spin ice
Masafumi Udagawa, Roderich Moessner
We study the quantum dynamics of fractional excitations in quantum spin ice. We focus on the density of states in the two-monopole sector, , as this can be connected to the w…
