The quantum entanglement of a wave function generates the information entropy carried by each qubit of the many-body system and correspondingly creates unique quantum matter. In this work, the authors attempt to visualize distinct quasiparticles and collective motions from an entanglement perspective. Remarkably, many salient features of the quasiparticles, including their quantum numbers, locality, and fractionalization, are reflected in the entanglement spectrum and in the mutual information.

Noncentrosymmetric CeBiPd has recently attracted tremendous attention as a strongly correlated topological semimetal candidate. Conflicting experimental results, however, argue for either a Weyl Kondo semimetallic or a narrow-gap Kondo insulating ground state. Using electrical transport measurements on bulk crystals and microstructure devices under hydrostatic pressure, the authors show that CeBiPd exhibits a narrow-gap Kondo insulating ground state. The results provide important evidence for the ground state of a sought-after Weyl Kondo semimetal candidate and shed light on the experimental and theoretical search for strongly correlated topological materials.

Stark many-body localization (MBL) occurs when interacting quantum particles are placed in a strong linear field gradient. Localization of excitations, coherent Bloch oscillations, Hilbert-space fragmentation, and scarring have been observed numerically and experimentally, but their origin is not understood. The authors explain these features analytically by perturbatively constructing an algebraic structure of Stark MBL Hamiltonians they name “dynamical l-bits”. These structures are exponentially stable in the field gradient strength. Thus, the work has potential implications for quantum information processing.
