Path Integral Approach to Quantum Fisher Information
Francis J. Headley, Mahdi RouhbakhshNabati, Henry Harper-Gardner +3
We present a real-time path-integral formulation of the quantum Fisher information for dynamical parameter estimation. For pure states undergoing unitary evolution, we show that th…

GMOR relation for a QCD-like theory from S-duality
Adi Armoni, Henry Harper-Gardner
Following [1] we study a QCD-like gauge theory using a non-supersymmetric setup in type IIB string theory. The setup includes an plane and D3 anti-branes and it realises a…
