We investigate the quantum walk on the line when decoherences are introduced either through simultaneous measurements of the chirality and particle position, or as a result of …

The reversal of the time evolution of the local polarization in an interacting spin system involves a sign change of the effective dipolar Hamiltonian which refocuses the “spin …
We discuss the steady-state electronic transport in solid-state and molecular devices in the quantum regime. The decimation technique allows a comprehensive description of the …

In the long quest to identify and compensate the sources of decoherence in many-body systems far from the ground state, the varied family of Loschmidt echoes (LEs) became an …
The transmission of quantum information between different parts of a quantum computer is of fundamental importance. Spin chains have been proposed as quantum channels for …
Spectroscopic Properties of Inorganic and Organometallic Compounds provides a unique source of information on an important area of chemistry. Divided into sections mainly …

The experimental observation of spin waves by NMR spectroscopy is reported for a linear chain consisting of five scalar coupled 13C spins of lysine. Selective excitation of a first spin …

An ingenious pulse sequence devised by Zhang, S., Meier, BH, and Ernst, RR, 1992, Phys. Rev. Lett., 69, 2149 reverses the time evolution ('spin diffusion') of the local polarization in a …
We perform a brief but critical review of the Landauer picture of transport that clarifies how decoherence appears in this approach. On this basis, we present different models that allow …
