Matching Terahertz and Hall Mobilities as a Hallmark of Intrinsic Charge Transport in Metal-Halide Perovskites

This study demonstrates that intrinsic charge transport can extend across macroscopic lengths in epitaxial CsPbBr3_{3} single crystals by showing quantitative agreement between local terahertz and macroscopic Hall mobilities, thereby establishing a robust methodology for benchmarking intrinsic mobility in soft-lattice semiconductors.

Non-Hermitian Crystalline Braid Topology from Hermitian Projection: A Zero-Mode Resonance Mechanism

This paper demonstrates that non-Hermitian crystalline braid topology can emerge from a fully Hermitian, topologically trivial parent lattice through a zero-mode-resonant projection mechanism, where coupling to a sublattice-imbalanced zero mode induces a singular self-energy that quantizes the complex Berry phase and generates finite-frequency braid transitions observable in topolectrical circuits.

Descriptor Covariance and Correlation Hierarchy in Moiré Exciton Photoluminescence

This paper proposes a minimal descriptor-based disorder-filter theory that explains the spatial organization of photoluminescence spectra in moiré heterobilayers by revealing a hierarchy of correlation lengths and robust spectral-shape relations, enabling the inference of effective disorder parameters from hyperspectral data without requiring microscopic line assignment.

Spin SWAP operation in double quantum dots at the LaAlO3/SrTiO3 interface

This paper presents a systematic study of spin control during SWAP operations in double quantum dots at the LaAlO3_3/SrTiO3_3 interface, demonstrating that while large dots dominated by dxyd_{xy} orbitals exhibit high fidelity despite Rashba-type spin-orbit coupling, small dots involving higher-energy dxz/yzd_{xz/yz} orbitals suffer from significantly reduced SWAP fidelity.

How Similar Can Fractional Chern Insulators Be to Fractional Quantum Hall States? Moiré-Enhanced Gaps and Excitation-Spectrum Correspondence

This paper establishes a theoretical principle demonstrating that by selectively suppressing small-wave-vector and amplifying large-wave-vector electron-density modulations in flat Chern bands, the fractional Chern insulator gap and excitation spectrum can be arbitrarily enhanced and made to correspond predictably to fractional quantum Hall states, thereby providing practical diagnostics for robust non-Abelian states in moiré systems.

Driving Exchange Interaction in Spin Qubits with Quasi-Zero Pulses

This paper introduces quasi-zero pulse designs to mitigate exchange interaction distortions in spin qubits, demonstrating on Intel's Tunnel Falls device that this approach achieves high-fidelity gates comparable to full filtering methods while significantly reducing calibration complexity and parameter tuning requirements.
