Research: Design principles for quantum devices
I work in the interdisciplinary research area of ``open quantum systems". I am interested in understanding the fundamentals of quantum chemical dynamics, quantum transport at the nanoscale, and quantum thermodynamics. By developing methodologies and implementing new computational treatments, my group is addressing, from microscopic principles, novel applications in chemical dynamics, molecular-level electronics, thermal energy management and optoelectronics. Our efforts are currently directed in the following areas:
(1) Quantum transport, fluctuations and quantum thermodynamics
Nature 562, 240 (2018)
Phys. Rev. E 98, 012117 (2018)
(2) Heat transfer in molecular junctions.
Annu. Rev. Phys. Chem. 2016. 67, 185-209.
(3) Charge transport in molecular junctions, particularly, biological molecules.
