Ultrafast Dynamics in a Photo-induced Symmetry-breaking Transition

The study of the suppression of an order parameter by an external perturbation and the following recovery of the broken-symmetry phase is a problem relevant to systems even beyond condensed matter physics. In the context of pump-probe experiments, it has been tackled considering the suppression of the charge density wave order parameter in several compounds, and it was found a relevant role played by the fluctuations [1,2].

Probing Electronic Structure and Magnetism in Low Dimensionality - An Experimental Approach

The ever-growing need for next-generation electronic and magnetic devices calls for new solutions for the engineering of quantum materials, in terms of miniaturization, energy consumption and speed compared to reference benchmarks, e.g. 18 ps for the Larmor magnetization switching. A new paradigm has emerged: the effect of the decrease of dimensionality in magnetic materials is recently being given a large deal of attention. [more]

Visualizing Electron Localization and Minibands in WS2/WSe2 Moiré Superlattices

  • PC Department Online Seminar
  • Date: Nov 29, 2021
  • Time: 09:00 AM (Local Time Germany)
  • Speaker: Conrad Stansbury
  • University of California, Berkeley
  • Host: Tommaso Pincelli
The ability to engineer flattened electronic bands by controlling interlayer effects in moiré superlattices of two-dimensional materials has opened the door for material physicists to understand and control correlated electron phenomena in an unprecedentedly broad class of materials. Despite wide-ranging transport and optical signatures of correlated phases, a holistic understanding of how exotic quantum phases emerge remains elusive. [more]
