This study demonstrates that the Josephson current in the quantum Hall regime is mediated by counter-propagating edge states confined to physical edges, resolving previous ambiguities regarding its mechanism through a systematic comparison of various edge configurations in graphene devices.
This paper demonstrates that the fully data-driven ESPRIT algorithm effectively compresses and denoises real-time quantum simulation data to accurately extrapolate long-time dynamical behavior and characterize quantum phases, even in noisy conditions and with limited short-time data.
This paper establishes a unified framework for Euler band topology in superfluids and superconductors by demonstrating that specific three-dimensional topological phases in symmetry classes DIII and CI, including the B phase of superfluid Helium-3, possess nontrivial Euler classes that link to known invariants and predict unique phenomena such as linked nodal lines and higher-order topology.
This paper demonstrates that volume-law entanglement can be generated in a one-dimensional fermionic system without intrinsic unitary dynamics by employing a non-random, non-commuting local measurement protocol involving an auxiliary chain and detector qubits, while also showing that non-local higher-body measurements can be used to control and reduce such entanglement.
This study utilizes multi-valley Monte Carlo simulations to reveal that electron transport in cryogenic Si(110) devices with high- oxides is governed by a competition between remote Coulomb and surface roughness scattering at low fields, while remote phonon scattering and phonon emission significantly limit mobility and velocity at high fields.
This paper introduces the FIRE-Swap first-principles framework, which utilizes machine-learning interatomic potentials to reveal that lead magnesium niobate (PMN) possesses a unique rock-salt-like chemical order and interconnected polar nanoregions within Nb clusters, providing a mesoscale explanation for its relaxor ferroelectricity that distinguishes it from PZT and PST.
This paper demonstrates that a system of three laterally coupled minimal Kitaev chains exhibits a highly tunable nonlocal Josephson diode effect, characterized by asymmetric critical currents exceeding 50% efficiency, which arises from an imbalance between crossed Andreev reflections and electron cotunneling that breaks local time-reversal and charge-conjugation symmetries.
This theoretical study proposes that capacitively coupled double quantum dots can serve as a robust nonlocal probe for Majorana bound states by revealing distinctive, symmetric split peaks in drag transconductance that clearly distinguish them from trivial subgap states.
This study demonstrates that coupling a plasmonic Su-Schrieffer-Heeger chain of InSb nanoparticles to an InSb substrate enables long-range radiative heat transfer mediated by surface modes, where topologically protected edge modes in the non-trivial phase significantly enhance heat transport compared to the trivial phase.
This study demonstrates that applying mechanical biaxial strain to WS2 can effectively tune exciton-phonon resonance, enabling controlled transitions between resonant and non-resonant Raman scattering at a fixed laser energy by red-shifting the B exciton by 180 meV.
