Symposia Day (DCMMP - DPMCM) - Fluctuations, interactions and Disorder in Condensed Matter / Fluctuations, interactions et désordre dans la matière condensée

Invited Speaker / Conférencier(ère) invité(e)

Heavy fermion compounds are strongly correlated systems with partially filled 4f or 5f electron bands. The ground states of heavy fermion materials are determined by a competition between the on-site Kondo interaction that screens the local 4f or 5f magnetic moments and the inter-site Ruderman-Kittel-Kasuya-Yosida exchange interaction. Muon spin rotation and relaxation ($\mu$SR) techniques...

4423. Detecting and quantifying orbital magnetism in moiré quantum matter

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier(ère) invité(e)

Newly discovered properties of magic angle graphene and other systems from the same family propelled the field of twistronics and motivated new research into tunable unconventional quantum phases. The research is driven in part by the search for robust quantum anomalous Hall insulators, topological superconductivity, correlated electronic states, and fractional statistics and by the prospect...

4093. Time-resolved ARPES at the Advanced Laser Light Source (ALLS) user facility – new insights into the ultrafast quench of superconductivity in Bi-based cuprates

Symposia Day (DCMMP - DPMCM) - Fluctuations, interactions and Disorder in Condensed Matter / Fluctuations, interactions et désordre dans la matière condensée

Invited Speaker / Conférencier(ère) invité(e)

Time- and angle-resolved photoemission spectroscopy (TR-ARPES) is a powerful technique for exploring intrinsic and light-induced electrodynamics in quantum materials [1]. In this talk, I will present the novel TR-ARPES endstation and the Advanced Laser Light Source (ALLS) user facility. I will show how, by combining sample voltage bias and a hemispherical electron analyzer with next generation...
