This paper demonstrates the first optical switching of diamond's effective second-order susceptibility () by utilizing a nanoscale cavity to modulate nitrogen-vacancy center charge states via photoionization, thereby enabling controllable second-harmonic generation.
This paper presents a general theoretical framework using semiconductor Bloch equations in a co-moving reference frame to demonstrate that intraband carrier motion significantly influences the optical polarization of two-dimensional materials, such as transition metal dichalcogenide monolayers, under intense non-resonant optical fields.
The paper introduces a linear-scaling stochastic method that utilizes positive-definite estimators and the Markov inequality to rigorously bound sampling errors, enabling accurate computation of real-space maps for local spectral operators and non-diagonal observables in large disordered lattices.
This paper presents a quantum-path electron interferometer based on time- and angle-resolved photoemission spectroscopy that successfully reconstructs the previously inaccessible phase of electronic wavefunctions, demonstrated by resolving the phase jumps and helicity of Dirac states in a topological insulator.
This study demonstrates that direct-write laser annealing can pattern phase gradients in tungsten thin films to create spin-orbit torque channels capable of switching CoFeB magnetization without external magnetic fields, offering a new strategy for designing efficient spintronic devices.
This paper demonstrates that in a two-dimensional Rashba film with an in-plane Zeeman field and short-range disorder, the total area of the Fermi contours remains invariant under the field, causing the leading quasiclassical conductivity to be isotropic and field-independent, thereby precluding anisotropic magnetoresistance unless physics beyond this mechanism is considered.
This paper reports the successful on-surface synthesis and comprehensive characterization of one-dimensional carbon nanostructures featuring periodic graphitic nitrogen substitution, demonstrating their tunable electronic and magnetic properties that transition from an open-shell to a closed-shell ground state upon adsorption on a gold surface.
This paper proposes a scalable, engineered dissipation framework that robustly prepares and stabilizes multimode multinomial cat states in bosonic systems, significantly extending their lifetimes against decoherence to enhance their utility in quantum technologies.
This study experimentally demonstrates a length scale effect in contact electrification within permalloy and degenerately doped p-Si heterostructures, where interfacial charge penetration depth varies with film thickness (51 nm for 2 μm vs. full thickness for 400 nm) due to flexoelectricity-mediated screening, ultimately inducing a metal-insulator transition.
This study demonstrates a label-free, real-time graphene electrolyte-gated field-effect transistor capable of highly sensitive, non-Faradaic detection of human serum albumin across a wide concentration range by leveraging electric double-layer capacitance and disorder-enhanced carrier scattering to transduce electrostatic perturbations into measurable conductance modulation.
