This paper presents an all-dielectric silicon-integrated metasurface composed of Si/GeSn core/shell nanowire arrays that enables polarization-tuned Fano resonances in the short-wave infrared spectrum, facilitating efficient refractive index sensing with a detection limit of 10⁻².
This paper employs Markovian Lindblad quantum dynamics to model electron transport in incoherently-driven molecular nanojunctions, demonstrating that the theory successfully reproduces key experimental features like negative differential conductance and Coulomb blockade while predicting light-induced currents in specific two-site configurations.
This paper employs a time-dependent Newns-Anderson-Schmickler model with Keldysh Green's functions and semiclassical trajectories to demonstrate how adsorbate motion and solvent coupling non-adiabatically suppress electron transfer while facilitating energy dissipation into electron-hole pairs, ultimately deriving an analytical expression for the average energy transfer rate in the slow-motion limit.
This paper introduces a radiofrequency electron-cascade readout method for silicon spin qubits that utilizes alternating-current electron co-tunnelling to achieve a signal-to-noise ratio enhancement of over 35 dB, enabling fast, high-fidelity singlet-triplet readout and coherent spin control without the need for proximal charge sensors.
This paper presents a non-phenomenological influence functional framework to model simultaneous fermionic and bosonic dissipation, revealing how electronic friction and solvent effects distinctly influence quantum vibrational relaxation and charge transfer dynamics in electrochemical systems.
This paper demonstrates that solid neon serves as a noise-resilient host for electron qubits, maintaining coherence times exceeding 1 s at temperatures up to 400 mK with charge noise levels comparable to common semiconductor hosts.
Using time-domain terahertz emission spectroscopy, researchers observed a dynamic magneto-chiral instability in photoexcited tellurium, where an electric current parallel to a magnetic field amplifies electromagnetic waves, offering a promising mechanism for THz-wave amplification in chiral materials.
This paper constructs 3+1D and 2+1D Hamiltonian lattice models for Weyl fermions and Dirac cones that evade no-go theorems by utilizing exact, not-on-site chiral symmetries—specifically a Ginsparg-Wilson analog and an Onsager algebra—to protect gaplessness and generate global anomalies even in the absence of crystalline translations.
This paper demonstrates that Coulomb interactions in correlated metals enable low-frequency optical conductivity to encode the quantum geometric structure of Bloch wavefunctions at the Fermi surface, offering a new optical probe for orbital character changes in topological band inversions.
This paper investigates the ground state of two-dimensional abelian anyons in a trapping potential by deriving and numerically validating a magnetic Thomas-Fermi density functional theory, which successfully captures the system's behavior and its dependence on the magnetic flux fraction attached to the particles.
