Quantum Pumping with Adiabatically Modulated Barriers in Three-Band Pseudospin-1 Dirac–Weyl Systems
In this work, pumped currents of the adiabatically-driven double-barrier structure based on the pseudospin-1 Dirac⁻Weyl fermions are studied. As a result of the three-band dispersion and hence the unique properties of pseudospin-1 Dirac⁻Weyl ...

Quantum State of the Fermionic Carriers in a Transport Channel Connecting Particle Reservoirs
We analyze the quantum state of fermionic carriers in a transport channel attached to a particle reservoir. The analysis is done from first principles by considering microscopic models of the reservoir and transport channel.

Vibrationally assisted quantum energy pumps
We show that directed energy transport in a linear array of coupled quantum dots can be achieved by a coherent coupling of each dot to a single coherently driven mechanical mode.

Spin transport in a quantum wire [PDF]
We study the effect of electron-electron backscattering interactions on spin transport in a quantum wire. Even if these interactions have no significant effect on charge transport, they strongly influence the transport of spin. We use the quantum Boltzmann equation in the collision approximation to derive equations of motion for spin current and ...

Investigation of carbon nanotube quantum dots connected to ferromagnetic leads [PDF]
The implementation of ferromagnetic contacts in complex nanoelectronic devices, e.g. in spin-valves bears great potential for applications and fundamental investigations. Spin-valves are structures with two magnetic contacts and a non-magnetic medium (

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Dynamic heat transport in open quantum systems [PDF]
Heat transport in driven nanoscale systems plays a critical role in quantum technologies and in non-equilibrium thermodynamics. More specifically, the investigation of time-dependent temperatures in quantum systems is a developing field that has seen ...
