On the alleged nonlocal and topological nature of the molecular Aharonov-Bohm effect
Erik Sjöqvist
The nonlocal and topological nature of the molecular Aharonov-Bohm (MAB) effect is examined for real electronic Hamiltonians. A notion of preferred gauge for MAB is suggested. The…
Relation between geometric phases of entangled bi-partite systems and their subsystems
D. M. Tong, E. Sjöqvist, L. C. Kwek +2
This paper focuses on the geometric phase of entangled states of bi-partite systems under bi-local unitary evolution. We investigate the relation between the geometric phase of the…
Noncyclic mixed state phase in SU(2) polarimetry
Peter Larsson, Erik Sjöqvist
We demonstrate that Pancharatnam's relative phase for mixed spin states in noncyclic SU(2) evolution can be measured polarimetrically.
Measuring Pancharatnam's relative phase for SO(3) evolutions using spin polarimetry
Peter Larsson, Erik Sjöqvist
In polarimetry, a superposition of internal quantal states is exposed to a single Hamiltonian and information about the evolution of the quantal states is inferred from projection…
