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…
