A "Square-root" Method for the Density Matrix and its Applications to Lindblad Operators
A. Yahalom, R. Englman
The evolution of open systems, subject to both Hamiltonian and dissipative forces, is studied by writing the element of the time () dependent density matrix in the form \be…
Conductance Phases in Aharonov-Bohm Ring Quantum Dots
A. Yahalom, R. Englman
The regimes of growing phases (for electron numbers N~0-8) that pass into regions of self-returning phases (for N>8), found recently in quantum dot conductances by the Weizmann gro…
Generic Short-Time Propagation of Sharp-Boundaries Wave Packets
Er'el Granot, Avi Marchewka
A general solution to the "shutter" problem is presented. The propagation of an arbitrary initially bounded wavefunction is investigated, and the general solution for any such func…
On the significance of a recent experiment demonstrating quantum interference in time
Lawrence P. Horwitz
I comment on the interpretation of a recent experiment showing quantum interference in time. It is pointed out that the standard nonrelativistic quantum theory, used by the authors…
