C\ast-geometric phase for mixed states: entanglement, decoherence and spin system
David Viennot, José Lages
We study a kind of geometric phases for entangled quantum systems, and particularly a spin driven by a magnetic field and entangled with another spin. The new kind of geometric pha…
The role of the geometric phases in adiabatic populations tracking for non-hermitian hamiltonians
Arnaud Leclerc, David Viennot, Georges Jolicard
We show that the definition of instantaneous eigenstate populations for a dynamical non-self-adjoint system is not obvious. The naive direct extension of the definition used for th…
Constrained Adiabatic Trajectory Method (CATM): a global integrator for explicitly time-dependent Hamiltonians
Arnaud Leclerc, Georges Jolicard, David Viennot +1
The Constrained Adiabatic Trajectory Method (CATM) is reexamined as an integrator for the Schrödinger equation. An initial discussion places the CATM in the context of the differen…
