A Biophysical Systems Approach to Identifying the Pathways of Acute and Chronic Doxorubicin Mitochondrial Cardiotoxicity. [PDF]
PLoS Computational Biology, 2016 The clinical use of the anthracycline doxorubicin is limited by its cardiotoxicity which is associated with mitochondrial dysfunction. Redox cycling, mitochondrial DNA damage and electron transport chain inhibition have been identified as potential ...

Transport of Spin Qubits with Donor Chains under Realistic Experimental Conditions [PDF]
Phys. Rev. B 94, 045314 (2016), 2016 The ability to transport quantum information across some distance can facilitate the design and operation of a quantum processor. One-dimensional spin chains provide a compact platform to realize scalable spin transport for a solid-state quantum computer.

Regimes of correlated hopping via a two-site interacting chain [PDF]
Phys. Rev. B 74, 035117 (2006), 2006 Inelastic transport of electrons through a two-impurity chain is studied theoretically with account of intersite Coulomb interaction, U. Both limits of ohmic transport (at low bias) and strongly non-ohmic transport (at high bias) are considered.

Transport properties of an interacting Majorana chain [PDF]
Phys. Rev. B 96, 205442 (2017), 2017 We study a one-dimensional (1D) chain of $2N$ Majorana bound states, which interact through a local quartic interaction. This model describes for example the edge physics of a quasi 1D stack of $2N$ Kitaev chains with modified time-reversal symmetry $T\gamma_iT^{-1}=\gamma_i$, which precludes the presence of quadratic coupling.

Incoherent transport induced by a single static impurity in a Heisenberg chain [PDF]
Phys. Rev. B 80, 125118 (2009)., 2009 The effect of a single static impurity on the many-body states and on the spin and thermal transport in the one-dimensional anisotropic Heisenberg chain at finite temperatures is studied. Whereas the pure Heisenberg model reveals Poisson level statistics and dissipationless transport due to integrability, we show using the numerical approach that a ...

Crossover from time-correlated single-electron tunneling to that of Cooper pairs
, 2007 We have studied charge transport in a one-dimensional chain of small Josephson junctions using a single-electron transistor. We observe a crossover from time-correlated tunneling of single electrons to that of Cooper pairs as a function of both magnetic ...

Magnetism and Spin Transport of Carbon Chain between Armchair Graphene Nanoribbon electrodes [PDF]
, 2016 The magnetic and spin transport properties of a carbon chain between two armchair graphene nanoribbon (AGNR) electrodes were studied using tight-binding Hamiltonian, mean-field Hubbard model and Landauer-Butikker formalism. The results showed that only odd-numbered carbon chains show intrinsic magnetic moments in chain-graphene junctions.

Energetic Electron Transport in Magnetic Fields with Island Chains and Stochastic Regions [PDF]
arXiv, 2023 This paper investigates energetic electron transport in magnetized toroidal plasmas with magnetic fields characterized by island chains and regions of stochastic field lines produced by coil perturbations. We report on experiments performed in the DIII-D tokamak, which utilize electron cyclotron heating and current drive pulses to tag electron ...
