Stability of the smectic phase in arrays of parallel quantum wires
Geo Jose, Bruno Uchoa
Using bosonization, we study a microscopic model of parallel quantum wires constructed from two dimensional Dirac fermions in the presence of periodic topological domain walls. The…
Non-Fermi liquid behavior in the Sachdev-Ye-Kitaev model for a one dimensional incoherent semimetal
Geo Jose, Kangjun Seo, Bruno Uchoa
Abstract We study a two-band dispersive Sachdev-Ye-Kitaev (SYK) model in 1 + 1 dimension. We suggest a model that describes a semimetal with quadratic dispersion at half-filling. W…
Automatic Learning of Topological Phase Boundaries
Alexander Kerr, Geo Jose, Colin Riggert +1
Topological phase transitions, which do not adhere to Landau's phenomenological model (i.e. a spontaneous symmetry breaking process and vanishing local order parameters) have been…
Hydrodynamic transport and violation of the viscosity-to-entropy ratio bound in nodal-line semimetals
Sang Wook Kim, Geo Jose, Bruno Uchoa
The ratio between the shear viscosity and the entropy is considered a universal measure of the strength of interactions in quantum systems. This quantity was conjectured to h…
Quantum critical scaling of gapped phases in nodal-line semimetals
Geo Jose, Bruno Uchoa
We study the effect of short range interactions in three dimensional nodal-line semimetals with linear band crossings. We analyze the Yukawa theories for gapped instabilities in th…
Phase diagram for the Harper model of the honeycomb lattice
Geo Jose, Rajesh Malla, Varadharajan Srinivasan +2
The Harper equation arising out of a tight-binding model of electrons on a honeycomb lattice subject to a uniform magnetic field perpendicular to the plane is studied. Contrasting…
