Quantum transport on honeycomb networks. [PDF]
Sci Rep, 2022 AbstractWe study the transport properties on honeycomb networks motivated by graphene structures by using the continuous-time quantum walk (CTQW) model. For various relevant topologies we consider the average return probability and its long-time average as measures for the transport efficiency.

Quantum Transport of Particles and Entropy. [PDF]
Entropy (Basel), 2021 A unified view on macroscopic thermodynamics and quantum transport is presented. Thermodynamic processes with an exchange of energy between two systems necessarily involve the flow of other balancable quantities. These flows are first analyzed using a simple drift-diffusion model, which includes the thermoelectric effects, and connects the various ...

Quantum transport in protein chains. [PDF]
Sci RepThe examination of the current-voltage properties of protein chains connected to armchair graphene nanoribbon leads is performed using the tight-binding Hamiltonian approach in conjunction with the Landauer-Büttiker formalism. The nonlinear current-voltage behavior for three different conformations of the protein structures is calculated and evaluated ...

Emergence of steady quantum transport in a superconducting processor [PDF]
Nature CommunicationsNon-equilibrium quantum transport is crucial to technological advances ranging from nanoelectronics to thermal management. In essence, it deals with the coherent transfer of energy and (quasi-)particles through quantum channels between thermodynamic ...

Interlayer quantum transport in Dirac semimetal BaGa2 [PDF]
Nature Communications, 2020 The transport behavior at the quantum limit may show exotic phenomena such as special interlayer quantum transport. Here, the authors observe negative interlayer magnetoresistance resulted from tunneling of Dirac fermions between the zeroth Landau levels

Quantum Optimal Transport with Quantum Channels [PDF]
Annales Henri Poincaré, 2021 We propose a new generalization to quantum states of the Wasserstein distance, which is a fundamental distance between probability distributions given by the minimization of a transport cost. Our proposal is the first where the transport plans between quantum states are in natural correspondence with quantum channels, such that the transport can be ...

Quantum Optimal Transport is Cheaper [PDF]
Journal of Statistical Physics, 2020 We compare bipartite (Euclidean) matching problems in classical and quantum mechanics. The quantum case is treated in terms of a quantum version of the Wasserstein distance introduced in [F. Golse, C. Mouhot, T. Paul, Commun. Math. Phys. 343 (2016), 165-205]. We show that the optimal quantum cost can be cheaper than the classical one.
