Bures metric over thermal state manifolds and quantum criticality
Paolo Zanardi, Lorenzo Campos Venuti, Paolo Giorda
We analyze the Bures metric over the manifold of thermal density matrices for systems featuring a zero temperature quantum phase transition. We show that the quantum critical regio…

The differential information-geometry of quantum phase transitions
P. Zanardi, P. Giorda, M. Cozzini
The manifold of coupling constants parametrizing a quantum Hamiltonian is equipped with a natural Riemannian metric with an operational distinguishability content. We argue that th…
