Leggett-Garg Inequality Violations Bound Quantum Fisher Information
Nick Abboud, Yuntao Guan, Barry Bradlyn +1
We prove that a violation of a Leggett-Garg inequality for bounded observables in stationary pure states and thermal states yields a rigorous lower bound on the quantum Fisher info…
Perfect spinfluid: A divergence-type approach
Nick Abboud, Lorenzo Gavassino, Rajeev Singh +1
We present a new formulation of non-dissipative relativistic spin hydrodynamics that incorporates spin degrees of freedom into the divergence-type theory framework. Due to the dive…
Observation of a dynamic magneto-chiral instability in photoexcited tellurium
Yijing Huang, Nick Abboud, Yinchuan Lv +12
In a system of charged chiral fermions driven out of equilibrium, an electric current parallel to the magnetic field can generate a dynamic instability by which electromagnetic wav…
First-order relativistic hydrodynamics with an information current
Lorenzo Gavassino, Nick Abboud, Enrico Speranza +1
We show that it is possible to define a timelike future-directed information current within relativistic first-order hydrodynamics. This constitutes the first step toward a covaria…
A new causal and stable theory of viscous chiral hydrodynamics
Nick Abboud, Enrico Speranza, Jorge Noronha
We construct the general theory of first-order relativistic hydrodynamics for a fluid exhibiting a chiral anomaly, including all possible viscous terms allowed by symmetry. Using s…
Signatures of Majorana bound states and parity effects in two-dimensional chiral p-wave Josephson junctions
Nick Abboud, Varsha Subramanyan, Xiao-Qi Sun +3
We characterize topological features of Josephson junctions formed by coupled mesoscopic chiral -wave superconducting islands. Through analytic and numerical studies of the low-…
