Nonequilibrium thermodynamics of the acoustoelectric quantum vacuum
Ryan O. Behunin, Andrew Shepherd, Francesco Intravaia +1
The quantum vacuum can assume thermal properties as a consequence of system kinematics, highlighting the nuance of our definition of particles in quantum field theory. Here, we exp…

Noise and dynamics in acoustoelectric waveguides
Ryan O. Behunin, Andrew Shepherd, Ruoyu Yuan +5
We present a quantum field theoretic formulation of acoustoelectric interactions in waveguide-like systems of arbitrary cross-section. Building on an open quantum systems approach,…

Phonon decoherence produced by two-level tunneling states
Ryan O. Behunin, Taylor Ray, Dylan Chapman +3
Phonon modes within pristine crystalline resonators now routinely reach the quantum ground state. Such systems are attractive for quantum information science applications, as advan…
