Phys. Rev. B 110, L121101 (2024) - Published 3 September, 2024
This work elucidates how the quantum nature of photons affects the topology of the correlated photoelectron hybrid wave function. The authors reveal a fundamental relation between the Berry phase and the properties of exchanged photons with matter at light-matter hybridization points in the Brillouin zone. Furthermore, the cavity-mediated electronic interactions in graphene valleys are analytically derived for the case where the material is subject to enhanced vacuum fluctuations in a chiral cavity.

The electron-phonon interaction is the most fundamental phenomenon governing the intrinsic resistance of metals at finite temperatures. In semimetals, there is a characteristic phonon energy scale: the Bloch-Grüneisen temperature (). This separates the different regimes of - scattering and is the temperature at which the average phonon momentum becomes comparable to the Fermi momentum. Here, the authors show, through subkelvin experiments, that due effective recovery of Galilean invariance below , the electronic liquid in small Fermi surface metals undergoes an anomalous increase of viscosity accompanied by an unconventional suppression of quantum oscillation amplitudes.

The discovery of exotic properties in magic-angle twisted bilayer graphene (MATBG) established two-dimensional moiré structures as an exciting new platform for strongly correlated physics. The distinct features of MATBG include a fourfold spin-valley flavor degeneracy and two extraordinarily flat topologically fragile low-energy bands. Here, the authors seek to gain new insights into MATBG physics by applying RPA theory, which accounts for dynamic screening of long-range Coulomb interactions and establishes the crucial influence of correlations in compressible metallic states in expanding unbroken symmetry regions in the MATBG phase diagram.

Quantum impurity models are key for describing many-body effects in both open quantum systems and correlated quantum materials through embedding methods. Continuous time quantum Monte Carlo provides numerically exact solutions with convergence, where is the number of samples. Here, the authors show how the imaginary time integration can be performed using quasi Monte Carlo yielding parametrically better convergence. Benchmarks of the open source implementation accompanying the paper are shown to enable calculations with unprecedented accuracy.

The authors introduce here a class of topological semimetals, termed “Berry-dipole semimetals” (BDSMs), in three dimensions. Two representative characteristics in the Bloch band structure of BDSMs are the quadratic dispersion and dipole-structure Berry curvature near the band degeneracy. The BDSMs are shown to support a diversity of distinctive properties, such as anomalous paired Fermi arcs with identical spin polarization, anomalous Hall effect, orbital magnetic moment quantized in units of an effective Bohr magneton, and field orientation sensitive Landau levels.
