Quantum walk on the generalized birkhoff polytope graph
(2021-10-01)
We study discrete-time quantum walks on generalized Birkhoff polytope graphs (GBPGs), which arise in the solution-set to certain transportation linear programming problems (TLPs). It is known that quantum walks mix at most ...
Classical to quantum correspondence in dissipative directed transport
(American Physical Society, 2015-11)
We compare the quantum and classical properties of the (quantum) isoperiodic stable structures [(Q)ISSs],which organize the parameter space of a paradigmatic dissipative ratchet model, i.e., the dissipative modifiedkicked ...
The Scattering of Phonons by Infinitely Long Quantum Dislocations Segments and the Generation of Thermal Transport Anisotropy in a Solid Threaded by Many Parallel Dislocations
(MDPI, 2020)
A canonical quantization procedure is applied to the interaction of elastic waves-phonons-with infinitely long dislocations that can oscillate about an equilibrium, straight line, configuration. The interaction is implemented ...
DC voltage profile of a 1D pumped wire with two dynamical and one static impurities
(Elsevier Science, 2009-10)
In this work we study the behavior of the voltage profile of a 1D quantum wire with an impurity when transport is induced by two ac voltages that oscillating with a phase lag define a quantum pump. The voltage profile ...
Comment on "Universal Out-of-Equilibrium Transport in Kondo-Correlated Quantum Dots: Renormalized Dual Fermions on the Keldysh Contour"
(Amer Physical Soc, 2013-08)
It is shown that the lesser and greater self energies and Green functions calculated in a recent work on universal noequilibrium transport in interacting quantum dots [E. Mu~noz, C. J. Bolech, and S. Kirchner, Phys. Rev. ...
Dynamics of energy transport and entropy production in ac-driven quantum electron systems
(American Physical Society, 2016-07)
We analyze the time-resolved energy transport and the entropy production in ac-driven quantum coherent electron systems coupled to multiple reservoirs at finite temperature. At slow driving, we formulate the first and ...
Local and effective temperatures of quantum driven systems
(American Physical Society, 2010-01)
We introduce thermometers to define the local temperature of an electronic system driven out of equilibrium by local ac fields. We also define the effective temperature in terms of a local fluctuation-dissipation relation. ...
Gate voltage enhances the thermoelectric transport of quantum dots in graphene nanoribbons
(ElsevierPEBR, 2023-05-29)
Chemically derived graphene nanoribbons and quantum dots are unique nanostructures that offer more possibilities than 2D and 3D systems to tune their electronic properties due to the enhanced quantum confinement effects. ...
