A spin heat engine coupled to a harmonic-oscillator flywheel [PDF]
Phys. Rev. Lett. 123, 080602 (2019), 2018 We realize a heat engine using a single electron spin as a working medium. The spin pertains to the valence electron of a trapped $^{40}$Ca$^+$ ion, and heat reservoirs are emulated by controlling the spin polarization via optical pumping. The engine is coupled to the ion's harmonic-oscillator degree of freedom via spin-dependent optical forces.

Boundary condition and geometry engineering in electronic hydrodynamics
, 2019 We analyze the role of boundary geometry in viscous electronic hydrodynamics. We address the twin questions of how boundary geometry impacts flow profiles, and how one can engineer boundary conditions -- in particular the effective slip parameter -- to ...

Quantum state swapping via qubit network with Hubbard interaction [PDF]
Phys. Rev. B 73, 195122 (2006), 2005 We study the quantum state transfer (QST) in a class of qubit network with on-site interaction, which is described by the generalized Hubbard model with engineered couplings. It is proved that the system of two electrons with opposite spins in this quantum network of $N$ sites can be rigorously reduced into $N$ one dimensional engineered single Bloch ...
