Hydrodynamics as the effective field theory of strong-to-weak spontaneous symmetry breaking

X Huang, M Qi, JH Zhang, A Lucas - arXiv preprint arXiv:2407.08760, 2024 - arxiv.org
Inspired by the hunt for new phases of matter in quantum mixed states, it has recently been
proposed that the equivalence of microcanonical and canonical ensembles in statistical …

Nearly critical superfluid: effective field theory and holography

Y Bu, H Gao, X Gao, Z Li - Journal of High Energy Physics, 2024 - Springer
A bstract We study a nearly critical superfluid system from two complementary approaches.
Within the first approach, we formulate a Schwinger-Keldysh effective field theory (EFT) for …

Field theory of active chiral hard disks: A first-principles approach to steric interactions

E Kalz, A Sharma, R Metzler - Journal of Physics A: Mathematical …, 2024 - iopscience.iop.org
A first-principles approach for active chiral hard disks is presented, that explicitly accounts
for steric interactions on the two-body level. We derive an effective one-body equation for the …

Stochastic theory of nonlinear electrical circuits in thermal equilibrium

A Osborne, A Lucas - arXiv preprint arXiv:2406.11796, 2024 - arxiv.org
We revisit the theory of dissipative mechanics in RLC circuits, allowing for circuit elements to
have nonlinear constitutive relations, and for the circuit to have arbitrary topology. We …

Breakdown of hydrodynamics in a Galilean quantum Hall crystal

X Huang, A Lucas - arXiv preprint arXiv:2412.12535, 2024 - arxiv.org
We construct a nonlinear fluctuating hydrodynamic effective field theory for Galilean-
invariant quantum Hall systems with spontaneously broken translational symmetry …

Nanoscale sensing of spatial correlations in nonequilibrium current noise

Y Zhang, R Samajdar, S Gopalakrishnan - arXiv preprint arXiv:2404.15398, 2024 - arxiv.org
Nitrogen-vacancy centers are spatially resolved probes of current noise. So far, current
noise sensing with NV centers has primarily been used as a way to probe equilibrium …
