This paper introduces interferometric dual-AC resonance tracking (iDART), a technique that combines quadrature-phase differential interferometry with two-frequency resonance tracking to enable high-speed, pixel-resolved nanomechanical imaging by leveraging Brownian motion for resonance identification while using active electrical excitation to achieve the necessary signal-to-noise ratio.
This paper proposes a noise-robust spin--orbital qubit encoded in the -shell of a three-hole quantum dot within a Ge/SiGe heterostructure, which mitigates charge noise while enabling fast all-electrical control and two-qubit entangling gates via adiabatic shuttling.
This paper demonstrates that while midgap states in extended Su-Schrieffer-Heeger and Rice-Mele models produce distinct spectral interference under global illumination, local illumination of topological edge states selectively suppresses odd harmonics to yield dominant even-harmonic generation due to the zero-energy character and particle-hole symmetry of the edge modes.
This paper proposes a scheme to estimate the Quantum Fisher Information in general two-band solid-state systems using angle-resolved photoemission spectroscopy (ARPES) with tuned incidence angles and light polarization, thereby linking measurable spectral data to ground-state sensitivity and quantum metric properties.
This study characterizes the anisotropic lattice dynamics and chiral phonon behavior of the quasi-one-dimensional van der Waals semiconductor ZrSnS through combined experimental and theoretical analysis, while demonstrating its potential for polarization-sensitive optoelectronics via a nanowire device exhibiting giant anisotropic photoresponse.
This study demonstrates that molecular Haldane chains of spin-1 triangulene units grown on a superconducting surface exhibit parity-dependent coupling to the superconducting condensate, where odd-length chains with net spin-1 ground states form Yu-Shiba-Rusinov bound states while even-length chains with spin-0 ground states remain decoupled, thereby establishing a tunable mechanism for molecular spin qubits.
This study demonstrates through Pt NMR measurements that the -electron density of states is the critical factor governing the manifestation of the quantum size effect in Pt-Ni and Pt-Pd nanoparticles, with Ni content enhancing ferromagnetic correlations and revealing clear quantum energy discretization unlike in Pt-Cu systems.
This paper investigates topological phase transitions in the Su-Schrieffer-Heeger model with further neighbor hopping and staggered potential using fidelity susceptibility, demonstrating that the divergence of this metric at critical points and its associated scaling exponent remain consistent with those of the standard SSH model.
This paper demonstrates that parity-time () symmetry provides a robust measurement principle for elusive odd viscosity in time-reversal-broken fluids by mapping the odd Navier-Stokes equations to a Schrödinger-like framework and utilizing balanced loss and gain in coupled oscillator systems to achieve square-root-enhanced sensitivity through exceptional points.
This paper offers a unified pedagogical framework to clarify the distinct mathematical roles of position and time in the quantum wavefunction by separating background coordinates from spectral labels, thereby resolving common student misconceptions about time operators and Dirac notation without proposing a new interpretation of time.
