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…
Finite-temperature crossover from coherent magnons to energy superdiffusion in the PXP model
Shengtao Jiang, Jean-Yves Desaules, Marko Ljubotina +1
The PXP chain was recently shown to exhibit superdiffusive energy transport with Kardar-Parisi-Zhang-like scaling, , joining a growing number of spin chains with this…
Sinkhorn-Drifting Generative Models
Ping He, Om Khangaonkar, Hamed Pirsiavash +2
We establish a theoretical link between the recently proposed "drifting" generative dynamics and gradient flows induced by the Sinkhorn divergence. In a particle discretization, th…
Asymptotic freedom, lost: Complex conformal field theory in the two-dimensional nonlinear sigma model and its realization in Heisenberg spin chains
Christopher Yang, Thomas Scaffidi
The two-dimensional nonlinear sigma model (NLSM) is asymptotically free for : it exhibits neither a nontrivial fixed point nor spontaneous symmetry-breaking. Here we sh…
Krylov Winding and Emergent Coherence in Operator Growth Dynamics
Rishik Perugu, Bryce Kobrin, Michael O. Flynn +1
The operator wavefunction provides a fine-grained description of quantum chaos and of the irreversible growth of simple operators into increasingly complex ones. Remarkably, at fin…
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…
