A path-integral approach to quantum acoustics is developed here. In contrast to the commonly utilized particle perspective, this emerging field brings forth a long neglected but essential wave paradigm for lattice vibrations. Within the coherent state...

The early-time dynamics of many-body quantum chaotic systems is typically considered non-universal due to the divergence from the predictions of random matrix theory. The eigenstate stacking theorem, on the other hand, asserts uniformity in a phase space...

In 1958, Anderson proposed a new insulating mechanism in random lattices, now known as Anderson localization. It has been shown that a metal-insulating transition occurs in three dimensions, and that one-dimensional disordered systems can be solved...

One manifestation of classical ergodicity is a complete loss of memory of the initial conditions due to the eventual uniform exploration of phase space. In quantum versions of the same systems, classical ergodic traits can be broken. Here, we extend the...

The quantum acoustic framework has recently emerged as a non-perturbative, coherent approach to electron-lattice interactions, uncovering rich physics often obscured by perturbative methods with incoherent scattering events. Here, we model the coupled...

Quantum scars refer to eigenstates with enhanced probability density along unstable classical periodic orbits. First predicted 40 years ago¹, scars are special eigenstates that counterintuitively defy ergodicity in quantum systems whose classical...

We find that Anderson localization ceases to exist when a random medium begins to move, but another type of fundamental quantum effect, Planckian diffusion , rises to replace it, with  of order of unity. Planckian diffusion supercedes the Planckian speed...

A quantum eigenstate of a classically chaotic system is referred as scarred by an unstable periodic orbit if its probability density is concentrated in the vicinity of that orbit. Recently, a new class of scarring - variational scarring - was discovered...

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...

The dynamic spectra of pulsars frequently exhibit diverse interference patterns, often associated with parabolic arcs in the Fourier-transformed (secondary) spectra. Our approach differs from previous ones in two ways: first, we extend beyond the...

The intricate relationship between electrons and the crystal lattice is a linchpin in condensed matter, traditionally described by the Fröhlich model encompassing the lowest-order lattice-electron coupling. Recently developed quantum acoustics...

Recent theoretical investigations have revealed unconventional transport mechanisms within high Brillouin zones of two-dimensional superlattices. Electrons can navigate along channels we call superwires, gently guided without brute force confinement. Such...
