Quantum-geometry-enabled Landau-Zener tunneling in singular flat bands

This paper demonstrates that while singular flat bands generally exhibit localized Wannier-Stark states that preclude DC transport, a static electric field near band crossing points induces Landau-Zener tunneling driven by interband quantum geometry, specifically the maximal quantum distance and associated geometric phases, which delocalizes wavefunctions and enables nontrivial transport.

Electron-phonon interactions and instabilities in Weyl semimetals under magnetic fields and torsional strain

This paper investigates how the combination of external magnetic fields and torsional strain induces asymmetric pseudo-magnetic fields in type-I Weyl semimetals, utilizing renormalization group analysis to explore the resulting evolution of coupling parameters and the emergence of lattice instabilities driven by interactions between phonons and chiral Landau levels.

The Impact of Geometric Blockade on Thermoelectric Transport in Triangular Triple Quantum Dots

Using hierarchical equations of motion, this study demonstrates that alleviating geometric blockade in a triangular triple quantum dot system under low-temperature conditions significantly enhances heat current relative to electric current, thereby boosting thermopower and achieving a remarkably high thermoelectric figure of merit.

Quantum Metric Length as a Fundamental Length Scale in Disordered Flat Band Materials

This paper establishes the quantum metric length as a fundamental length scale governing electronic transport across ballistic, diffusive, and localization regimes in disordered flat band materials, notably revealing a disorder-independent localization regime and a linear relationship between diffusion coefficients and the quantum metric.

Strong Correlations in the Dynamical Evolution of Lowest Landau Level Bosons

This paper investigates the interaction-driven hydrodynamic instability of rotating Bose gases in the lowest Landau level within the low-density limit, demonstrating that the dynamics are governed by repulsively-bound few-body clusters whose signatures manifest as oscillating observables and a slow, power-law thermalization characteristic of quantum many-body scars.

Machine-Learned Hamiltonians for Quantum Transport Simulation of Valence Change Memories

This paper introduces an equivariant graph neural network approach that accurately predicts Hamiltonian matrices for large, non-periodic valence change memory systems containing thousands of atoms, thereby overcoming the computational and memory limitations of traditional density-functional theory to enable quantum transport simulations of large-scale devices.
