Coherent states of Pöschl-Teller potential and their revival dynamics

A recently developed algebraic approach for constructing coherent states for solvable potentials is used to obtain the displacement operator coherent state of the Pöschl-Teller potential. We establish the connection between this and the annihilation operator coherent state and compare their properties. We study the details of the revival structure arising from different time scales underlying t...

Many-body coherent destruction of tunneling.

A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulation can be tuned such that only an arbitrarily, a priori prescribed number of particles are allowed to tunnel. The associated tunneling dynamics is sensitive to the odd or even nature of the number of bosons.

Coherent resonant tunneling through an artificial molecule

Coherent resonant tunneling through an array of quantum dots in an inhomogeneous magnetic field is investigated using an extended Hubbard model. Both the multiterminal conductance of an array of quantum dots and the persistent current of a quantum-dot molecule embedded in an Aharanov-Bohm ring are calculated. The conductance and persistent current are calculated analytically for the case of a d...

Coherent Tunneling Transport in Molecular Junctions†

Using saturated alkyl chain series with a dithiol anchor group, we systematically examined the intrinsic charge transport of single-molecule junctions in an electromigrated nanogap electrode. The saturated alkyl molecular system constitutes an important control series in molecular transport experiments to corroborate valid molecular junctions, because molecular energy levels remain nearly uncha...

Coherent Tunneling and Instantons in Presence of Classical Chaos

The influence of classical chaos on dynamical tunneling1) in the semiclassical regime of quantum mechanics was observed in the pioneer work by Lin and Ballentine.2) Namely, it was detected in the numerical experiment that regions of chaotic motion in the classical phase space of the model system (periodically driven quartic double well) can enhance the rate of quantum tunneling between KAM-isla...
