Quantum critical theories in a periodic potential: strange metallic thermoelectric and magnetotransport
Eric Nilsson, Koenraad Schalm
We study DC and AC thermoelectric and magneto-transport in 2D quantum critical theories with strong translational symmetry breaking due to a % varying chemical potential lattice wi…
Josephson wormhole in coupled superconducting Yukawa-SYK metals
Aravindh S. Shankar, Jasper Steenbergen, Stephan Plugge +1
We show that two Yukawa-SYK models with a weak tunneling contact can have an exotic hybrid superconducting thermofield-double-like state that is holographically dual to a traversab…
Natural anomalous cyclotron response in a hydrodynamic local quantum critical metal in a periodic potential
Nicolas Chagnet, Sam Arend, Floris Balm +3
We study DC magnetotransport in a quantum critical metal in the presence of a lattice. In the regime where the transport is hydrodynamical the interplay of the Lorentz force and th…
Replicating Higgs fields in Ising gauge theory: the registry order
Aleksandar Bukva, Koenraad Schalm, Jan Zaanen
We consider gauge field theory coupled to "Higgs" matter fields invoking several copies of such matter, interacting entirely through the gauge fields, the $Z_2 \times Z_2 \ti…
Criticality versus uniformity in deep neural networks
Aleksandar Bukva, Jurriaan de Gier, Kevin T. Grosvenor +3
Deep feedforward networks initialized along the edge of chaos exhibit exponentially superior training ability as quantified by maximum trainable depth. In this work, we explore the…
Hydrodynamics of a relativistic charged fluid in the presence of a periodically modulated chemical potential
Nicolas Chagnet, Koenraad Schalm
We study charged hydrodynamics in a periodic lattice background. Fluctuations are Bloch waves rather than single momentum Fourier modes. At boundaries of the unit cell where hydrod…
