Hydrodynamic electronic transport
Lars Fritz, Thomas Scaffidi
The ``flow'' of electric currents and heat in standard metals is diffusive with electronic motion randomized by impurities. However, for ultraclean metals, electrons can flow like…
Kondo effect in twisted bilayer graphene
A. S. Shankar, D. O. Oriekhov, Andrew K. Mitchell +1
The emergence of flat bands in twisted bilayer graphene at the magic angle can be understood in terms of a vanishing Fermi velocity of the Dirac cone. This is associated with van H…
Lyapunov exponents in a Sachdev-Ye-Kitaev-type model with population imbalance in the conformal limit and beyond
A. S. Shankar, M. Fremling, S. Plugge +1
The Sachdev-Ye-Kitaev (SYK) model shows chaotic behavior with a maximal Lyapunov exponent. In this paper, we investigate the four-point function of a SYK-type model numerically, wh…
Hydrodynamics of charged two-dimensional Dirac systems II: the role of collective modes
Kitinan Pongsangangan, T. Ludwig, H. T. C. Stoof +1
We study the hydrodynamic properties of ultraclean interacting two-dimensional Dirac electrons with Keldysh quantum field theory. We study it from a weak-coupling and a strong-coup…
Hydrodynamics of charged two-dimensional Dirac systems I: thermo-electric transport
Kitinan Pongsangangan, T. Ludwig, H. T. C. Stoof +1
In this paper we study thermo-electric transport in interacting two-dimensional Dirac-type systems using a phenomenological Boltzmann approach. We consider a setup that can accommo…
Lower bounds for Ramsey numbers as a statistical physics problem
Jurriaan Wouters, Aris Giotis, Ross Kang +2
Ramsey's theorem, concerning the guarantee of certain monochromatic patterns in large enough edge-coloured complete graphs, is a fundamental result in combinatorial mathematics. In…
