Extrinsic phonon thermal Hall transport from Hall viscosity
Haoyu Guo, Subir Sachdev
Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the cuprates, we present an analysis of chiral phonon transport. We assume the chiral behav…
Critical anomalous metals near superconductivity in models with random interactions
Chenyuan Li, Darshan G. Joshi, Subir Sachdev
Anomalous metals are observed in numerous experiments on disordered two-dimensional systems proximate to superconductivity. A characteristic feature of an anomalous metal is that i…
Large theory of critical Fermi surfaces
Ilya Esterlis, Haoyu Guo, Aavishkar A. Patel +1
We describe the large saddle point, and the structure of fluctuations about the saddle point, of a theory containing a sharp, critical Fermi surface in two spatial dimensions.…
Phonon Hall viscosity from phonon-spinon interactions
Yunchao Zhang, Yanting Teng, Rhine Samajdar +2
Motivated by experimental observations, Samajdar et al. [Nature Physics 15, 1290 (2019)] have proposed that the insulating Neel state in the parent compounds of the cuprates is pro…
Small to large Fermi surface transition in a single band model, using randomly coupled ancillas
Alexander Nikolaenko, Maria Tikhanovskaya, Subir Sachdev +1
We describe a solvable model of a quantum transition in a single band model involving a change in the size of the electron Fermi surface without any symmetry breaking. In a model w…
Evidence of zero point fluctuation of vortices in a very weakly pinned a-MoGe thin film
Surajit Dutta, Indranil Roy, John Jesudasan +2
In a Type II superconductor, the vortex core behaves like a normal metal. Consequently, the single-particle density of states in the vortex core of a conventional Type II supercond…
