Information geometry provides a tool to systematically investigate parameter 1 sensitivity of the state of a system. If a physical system is described by a linear combination 2 of eigenstates of a complex (that is, non-Hermitian) Hamiltonian, then there can be phase 3 transitions where dynamical properties of the system change abruptly. In the vicinities of 4 the transition points, the state of the system becomes highly sensitive to the changes of the 5 parameters in the Hamiltonian. The… CONTINUE READING
