Bayesian Tracking of a Diffusing Target in Two and Three Dimensions
Ewan McCulloch, Adam Nahum
We study Bayesian tracking of a diffusing target monitored by a noisy distributed sensor array. Building on an earlier mapping to KPZ growth with a moving defect (or an equivalent…
Anomalous diffusion and singular transport from hydrodynamic recoupling
Ewan McCulloch, Romain Vasseur, Sarang Gopalakrishnan
In charge neutral fluids, such as the Dirac fluid in graphene at the Dirac point, charge transport remains diffusive despite the presence of ballistically propagating sound waves:…
Monitored Fluctuating Hydrodynamics
Sarang Gopalakrishnan, Ewan McCulloch, Romain Vasseur
We introduce a hydrodynamic framework for describing monitored classical stochastic processes. We study the conditional ensembles for these monitored processes -- i.e., we compute…
Ballistic Modes as a Source of Anomalous Charge Noise
Ewan McCulloch, Romain Vasseur, Sarang Gopalakrishnan
Steady-state currents generically occur both in systems with continuous translation invariance and in nonequilibrium settings with particle drift. In either case, thermal fluctuati…
Emergence of Navier-Stokes hydrodynamics in chaotic quantum circuits
Hansveer Singh, Ewan McCulloch, Sarang Gopalakrishnan +1
We construct an ensemble of two-dimensional nonintegrable quantum circuits that are chaotic but have a conserved particle current, and thus a finite Drude weight. The long-waveleng…
Non-Gaussian diffusive fluctuations in Dirac fluids
Sarang Gopalakrishnan, Ewan McCulloch, Romain Vasseur
Dirac fluids - interacting systems obeying particle-hole symmetry and Lorentz invariance - are among the simplest hydrodynamic systems; they have also been studied as effective des…
