Quantum “contact” friction: The contribution of kinetic friction coefficient from thermal fluctuations

Friction, 2023
A thermal model of kinetic friction is assigned to a classical loaded particle moving on a fluctuating smooth surface. A sinusoidal wave resembles surface fluctuations with a relaxation time. The Hamiltonian is approximated to the mean energy of the wave

Probing bath-induced entanglement in a qubit pair by measuring photon correlations [PDF]

, 2014
Self-assembled quantum dots (QDs) are ideal structures in which to test theories of open quantum systems: confined exciton states can be coherently manipulated and their decoherence properties are dominated by interactions with acoustic phonons.
