Phononic Casimir Effect in Planar Materials
Pablo Rodriguez-Lopez, Dai-Nam Le, Lilia M. Woods
The Phononic Casimir effect between planar objects is investigated by deriving a formalism from the quantum partition function of the system following multiscattering approach. Thi…
Quantum stick-slip motion in nanoscaled friction
Dai-Nam Le, Pablo Rodriguez-Lopez, Lilia M. Woods
Friction in atomistic systems is usually described by the classical Prandtl-Tomlinson model suitable for capturing the dragging force of a nanoparticle in a periodic potential. Her…
Phonon-assisted Casimir interactions between piezoelectric materials

Dispersive interactions between standard and Dirac materials and the role of dimensionality
Dai-Nam Le, Pablo Rodriguez-Lopez, Lilia M. Woods
The van der Waals (vdW) interaction plays a prominent role between neutral objects at separations where short ranged chemical forces are negligible. This type of dispersive couplin…
