Repulsion-Driven Superconductivity in a Single Valley Revealed by DMRG
Cesar A. Gallegos, Omid Tavakol, Christopher Yang +2
We demonstrate repulsion-driven topological superconductivity of a single species of Dirac fermions, motivated by valley-polarized phases observed in two-dimensional materials such…
Pairing around a Single Dirac Point: A Unifying View of Kohn-Luttinger Superconductivity in Chern Bands, Quarter Metals, and Topological Surface States
Omid Tavakol, Thomas Scaffidi
Superconductivity of a single two-dimensional Dirac fermion offers a natural route to topological superconductivity. While usually considered extrinsic -- arising from proximity to…
Electric field control of a quantum spin liquid in weak Mott insulators
Daniel J. Schultz, Alexandre Khoury, Félix Desrochers +3
The triangular lattice Hubbard model at strong coupling, whose effective spin model contains both Heisenberg and ring exchange interactions, exhibits a rich phase diagram as the ra…
Minimal model for the flat bands in copper-substituted lead phosphate apatite: Strong diamagnetism from multi-orbital physics
Omid Tavakol, Thomas Scaffidi
The claims that a copper-substituted lead apatite, denoted as CuPb(PO)OH, could be a room-temperature superconductor have led to an intense research activity. While…
Hidden Critical Points in the Two-Dimensional model: Exact Numerical Study of a Complex Conformal Field Theory
Arijit Haldar, Omid Tavakol, Han Ma +1
The presence of nearby conformal field theories (CFTs) hidden in the complex plane of the tuning parameter was recently proposed as an elegant explanation for the ubiquity of "weak…
Nonlinear optical responses in nodal line semimetals
Omid Tavakol, Yong Baek Kim
Shift current and second harmonic generation (SHG) are nonlinear optical responses that are often used for photovoltaic effect and the detection of subtle symmetry breaking pattern…
Pairing Instabilities of the Yukawa-SYK Models with Controlled Fermion Incoherence
Wonjune Choi, Omid Tavakol, Yong Baek Kim
The interplay of non-Fermi liquid and superconductivity born out of strong dynamical interactions is at the heart of the physics of unconventional superconductivity. As a solvable…
Variational wavefunctions for Sachdev-Ye-Kitaev models
Arijit Haldar, Omid Tavakol, Thomas Scaffidi
Given a class of -local Hamiltonians, is it possible to find a simple variational state whose energy is a finite fraction of the ground state energy in the thermodynamic limit?…
Artificial electric field and electron hydrodynamics
Omid Tavakol, Yong Baek Kim
In the electron dynamics in quantum matter, the Berry curvature of the electronic wave function provides the artificial magnetic field (AMF) in momentum space, which leads to non-t…
