Tunable heat pump by modulating the coupling to the leads [PDF]

open access: yesPhys. Rev. E 82, 021116 (2010), 2010
We follow the nonequilibrium Green's function formalism to study time-dependent thermal transport in a linear chain system consisting of two semi-infinite leads connected together by a coupling that is harmonically modulated in time. The modulation is driven by an external agent that can absorb and emit energy.

A Phenomenological Study of Pastoral Accountability in Covenant Community [PDF]

open access: yes, 2022
Most pastors and clergy minister from a place of a perceived divine calling and persist through the myriad of challenges of ministry, regardless of the personal toll that it takes on them. This tireless working can drive them to a place of poor emotional

Transport through a quantum dot with two parallel Luttinger liquid leads [PDF]

open access: yes, 2011
We study transport through a quantum dot side-coupled to two parallel Luttinger liquid leads in the presence of a Coulombic dot-lead interaction. This geometry enables an exact treatment of the inter-lead Coulomb interactions. We find that for dots symmetrically disposed between the two leads the correlation of charge fluctuations between the two leads

Biological impact of lead from halide perovskites reveals the risk of introducing a safe threshold

open access: yesNature Communications, 2020
Regulations currently in force enable to claim that the lead content in perovskite solar cells is low enough to be safe, or no more dangerous, than other electronics also containing lead.
