Second ac screening step as a probe for the first-order melting transition in layered vortex matter at intermediate temperatures

Gonzalo Rumi, Pablo Pedrazzini, Hernán Pastoriza +2

We present a new probe for the first-order transition for layered vortex matter: A second step in the screening of an ac field that is independent of the frequency and amplitude of…

Electron charge dynamics and charge separation: A response theory approach

Lionel Lacombe, Lucia Reining, Vitaly Gorelov

This study applies response theory to investigate electron charge dynamics, with a particular focus on charge separation. We analytically assess the strengths and limitations of li…

Thermal Hall conductivity in the strongest cuprate superconductor: Estimate of the mean free path in the trilayer cuprate HgBaCaCuO

Munkhtuguldur Altangerel, Quentin Barthélemy, Étienne Lefrançois +12

The thermal Hall conductivity of the trilayer cuprate HgBaCaCuO (Hg1223) - the superconductor with the highest critical temperature at ambient pressure -…
