Quantum acoustics unravels Planckian resistivity. [PDF]

Proc Natl Acad Sci U S A
Strange metals exhibit universal linear-in-temperature resistivity described by a Planckian scattering rate, the origin of which remains elusive. By employing an approach inspired by quantum optics, we arrive at the coherent state representation of lattice vibrations: quantum acoustics.

Physical acoustics in quantum fluids [PDF]

The Journal of the Acoustical Society of America, 1975
Superfluid helium is rich in the number of wave propagation modes which occur because it behaves as though it is composed of two fluids one of which is superfluid and the other a normal fluid. Four recognized modes are named first, second, third and fourth sound, of which all but the first occur only in quantum fluids.

Polaron catastrophe within quantum acoustics

Proceedings of the National Academy of Sciences
The quantum acoustic framework has recently emerged as a nonperturbative, coherent approach to electron–lattice interactions, uncovering rich physics often obscured by perturbative methods with incoherent scattering events. Here, we model the strongly coupled dynamics of electrons and acoustic lattice vibrations within this framework, representing ...

A quantum formalism for a terahertz acoustic laser [PDF]

Brazilian Journal of Physics, 1999
The aim of this work is to improve the study of a phonon laser (saser) proposed by us several years ago[1]. This is a device capable to generate an intense coherent beam of acoustical phonons. Our acoustic laser consists in a double barrier heterostructure tailored such the energy difference between the ground and the first excited state in the well is

Listening For New Physics With Quantum Acoustics [PDF]

We present a novel application of a qubit-coupled phonon detector to search for new physics, e.g., ultralight dark matter (DM) and high-frequency gravitational waves. The detector, motivated by recent advances in quantum acoustics, is composed of superconducting transmon qubits coupled to high-overtone bulk acoustic resonators ($h$BARs) and operates in

Quantum phase modulation with acoustic cavities and quantum dots

Optica, 2022
Fast, efficient, and low-power modulation of light at microwave frequencies is crucial for chip-scale classical and quantum processing as well as for long-range networks of superconducting quantum processors. A successful approach to bridge the gap between microwave and optical photons has been to use intermediate platforms, such as

Approximate Quantum and Acoustic Cloaking

Journal of Spectral Theory, 2011
For any E\ge 0 , we construct a sequence of bounded potentials V^E_{n},\, n\in\Bbb N , supported in {an annular region B_{out}\setminus B_{inn}\subset\Bbb R ^3 ,} which act as ...

Unified Simulation Methods for Quantum Acoustic Devices

Physical Review Applied, 2023
In circuit quantum acoustodynamics (cQAD), superconducting circuits are combined with acoustic resonators to create and control non-classical states of mechanical motion. Simulating these systems is challenging due to the extreme difference in scale between the microwave and mechanical wavelengths.
