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…
Noise dynamics in large mode volume Brillouin lasers
Andrew J. Shepherd, Daniel J. Blumenthal, Ryan O. Behunin
Photonic integrated Brillouin lasers have emerged as an important tool to realize a wide range of precision applications, including atomic time-keeping, low-noise microwave signal…
Frequency entangled W states and quantum frequency translation protocols via forward Brillouin interactions
Andrew J. Shepherd, Ryan O. Behunin
Complex quantum states of light are not only central to advancing our understanding of quantum mechanics, but are also necessary for a variety of quantum protocols. High-dimensiona…
Multi-phonon Fock state heralding with single-photon detection
Andrew J. Shepherd, Ryan O. Behunin
Recognized as a potential resource for quantum technologies and a possible testbed for fundamental physics, the control and preparation of nonclassical states of mechanical oscilla…
