Dual current anomalies and quantum transport within extended reservoir simulations

October 19, 2021
Author(s)
Gabriela Wojtowicz, Justin E. Elenewski, Marek Rams, Michael P. Zwolak
Quantum transport simulations are rapidly evolving, including the development of well–controlled tensor network techniques for many– body transport calculations. One particularly powerful approach combines matrix product states with extended reservoirs —

Performance of Reservoir Discretizations in Quantum Transport Simulations

September 29, 2021
Author(s)
Justin E. Elenewski, Gabriela Wojtowicz, Marek Rams, Michael P. Zwolak
Quantum transport simulations require a level of discretization, often achieved through an explicit representation of the electronic reservoirs. These representations should converge to the same continuum limit, though there is a trade-off between a given

Open-system tensor networks and Kramers' crossover for quantum transport

May 12, 2020
Author(s)
Gabriela Wojtowicz, Justin E. Elenewski, Marek Rams, Michael P. Zwolak
Tensor networks are a powerful tool for many-body ground-states with limited entanglement. These methods can nonetheless fail for certain time-dependent processes - such as quantum trans- port or quenches - where entanglement growth is linear in time

Topology, Landscapes, and Biomolecular Energy Transport

October 11, 2019
Author(s)
Justin E. Elenewski, Kirill Velizhanin, Michael P. Zwolak
While ubiquitous, energy redistribution remains a poorly understood facet of the nonequilibrium thermodynamics of biomolecules. At the molecular level, finite-size effects, pronounced nonlinearities, and ballistic processes conspire to produce behavior

Optimal transport and colossal ionic mechano-conductance in graphene crown ethers

July 12, 2019
Author(s)
Subin Sahu, Justin E. Elenewski, Christoph Rohmann, Michael P. Zwolak
Biological ion channels balance electrostatics and hydration, yielding large ion selectivities alongside high transport rates. These macromolecular systems are often interrogated through point mutations of their pore domain, limiting the scope of

A Spin-1 Representation for Dual-Funnel Energy Landscapes

July 20, 2018
Author(s)
Justin E. Elenewski, Kirill Velizhanin, Michael P. Zwolak
The interconversion between left- and right-handed helical folds of a polypeptide defines a dual-funneled free energy landscape. In this context, the funnel minima are connected through a continuum of unfolded conformations, evocative of the classical
