Thermoelectric quantum oscillations and Zeeman splitting in topological Dirac semimetal BaAl
P. R. Mandal, Kefeng Wang, Tarapada Sarkar +3
Three-dimensional topological semimetals hosting Dirac or Weyl fermions are a new kind of materials class in which conduction and valence bands cross each other. Such materials har…
A counterexample to the conjectured Planckian bound on transport
Nicholas R. Poniatowski, Tarapada Sarkar, Ricardo P. S. M. Lobo +2
It has recently been conjectured that the transport relaxation rate in metals is bounded above by the temperature of the system. In this work, we discuss the transport phenomenolog…
The Future of the Correlated Electron Problem
A. Alexandradinata, N. P. Armitage, Andrey Baydin +44
A central problem in modern condensed matter physics is the understanding of materials with strong electron correlations. Despite extensive work, the essential physics of many of t…
Strange Metallic Transport in the Antiferromagnetic Regime of Electron Doped Cuprates
Tarapada Sarkar, Nicholas R Poniatowski, Joshua S. Higgins +3
We report magnetoresistance and Hall Effect results for electron-doped films of the high-temperature superconductor LaCeCuO (LCCO) for temperatures from 0.7 to 45 K…
Resistivity saturation in an electron-doped cuprate
Nicholas R. Poniatowski, Tarapada Sarkar, Sankar Das Sarma +1
We report the observation of resistivity saturation in lightly doped ( as-grown samples of the electron-doped cuprate LaCeCuO (LCCO). The saturation oc…
Anomalous normal state magnetotransport in an electron-doped cuprate
Nicholas R. Poniatowski, Tarapada Sarkar, Richard L. Greene
We report magnetoresistance and Hall angle measurements of the electron-doped cuprate LaCeCuO over a wide range of dopings from . Above 100 K, we f…
