This paper theoretically proposes a rapid adiabatic passage-based super-resolution microscopy scheme for quantum dots that utilizes structured, chirped, and time-delayed beams to suppress diffraction rings and achieve high-resolution imaging, particularly under conditions where exciton-phonon decoupling preserves image quality at higher pulse areas.
This study utilizes density functional theory and non-equilibrium Green function methods to demonstrate that introducing monoatomic boron vacancies in hexagonal boron nitride layers sandwiching a three-atom-thick graphene layer creates a van der Waals magnetic tunnel junction capable of achieving a record-high tunneling magnetoresistance ratio of approximately 400% due to spin-dependent transmission differences between parallel and antiparallel magnetic configurations.
This study experimentally maps the topological band structure of three-terminal graphene Josephson junctions using tunnelling spectroscopy and magnetic flux control, revealing a transition from gapped to gapless Andreev bound states that mimics nodal-line semimetals and demonstrates the potential for engineering higher-dimensional topological phases.
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 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 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 paper demonstrates that hybrid systems combining -wave unconventional magnets and -wave superconductors induce an -wave-like superconducting state characterized by zero-energy flat bands, odd-frequency pairing, and tunable Josephson currents.
