Nonlinear optical charge state switching and pumping to a diamond NV center dark state

By utilizing a nanoscale cavity to generate intense infrared fields, this study identifies that the photoluminescence quenching in diamond nitrogen-vacancy centers is caused by nonlinear two-photon pumping into a previously misunderstood dark state of the neutral NV charge, thereby characterizing its energy levels and lifetime to establish performance limits for future quantum technologies.

The impact of intraband carrier dynamics on the optical properties of two-dimensional materials: I. General theory

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.

Resolving the phase of a Dirac topological state via interferometric photoemission

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.

Generating unconventional spin-orbit torques with patterned phase gradients in tungsten thin films

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.

Hybrid superinductance with Al/InAs

This paper reports the microwave spectroscopy of epitaxial Al/InAs Josephson junction chains that exhibit high-impedance superinductance and large plasma frequencies up to 12 GHz, while identifying a sharp frequency-dependent decrease in internal quality factors potentially linked to intrinsic losses in the superconductor-semiconductor junction.

Ultrafast Third-Harmonic Spectral Modulation and Self-Action in Resonant Nonlocal Metasurfaces

This study demonstrates how pulse duration and resonant coupling govern nonlinear self-action mechanisms in quasi-bound state-enabled dielectric metasurfaces, revealing distinct intensity-dependent third-harmonic generation regimes under picosecond and femtosecond excitation that bridge strong field confinement with conversion efficiency and spectral dynamics.

Anisotropic magnetoresistance of 2D Rashba films with in-plane Zeeman field and short-range disorder

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.
