• Abstract: We present an approach of analyzing the transport of a quantum particle in a non-trivially connected extended system interacting with a dissipative medium. There are broadly two different aspects of the problem that affect the route taken by the transport process. First is obviously the couplings between the various sites, which translates into the intrinsic "strength" of a channel. Apart from the inter-site couplings, the solvents affecting the energies of the sites, and their relative coupling strengths and time-scales form the second factor. This impact of the such dissipative media is significantly more difficult to analyze. The Channel-Dependent Population Transfer (CDPT) method of analyzing the transport allows us to account for both the effects in a rigorous manner. We demonstrate the richness hidden behind the transport even for relatively simple systems -- the effect of the local dissipative media is highly non-trivial and can mask the simplicity of the effect of the relative magnitude of the inter-site couplings. This opens up possibilities in terms of detailed study of the impact of factors on the nature of dynamics, especially possibilities of design of novel systems with an eye towards quantum control.

Interestingly, when the system is both interacting and (nearly-)integrable, we observe the coexistence of diffusive spin transport with ballistic energy transport.

  Landau-Zener (LZ) tunneling describes transitions in a two-level system during a sweep through an anti-crossing. Dissipation due to coupling between the system and environment is an important factor in determining the transition rates. We report experimental results on the dissipative LZ transition using a tunable superconducting flux qubit.
