This paper presents a highly efficient, monolithic semiconductor-dielectric microresonator source that utilizes an InAs/GaAs quantum dot to generate polarized C-band single photons with a record-breaking end-to-end efficiency of 11%, overcoming the limitations of conventional attenuated laser pulses for secure quantum communications.
Using optically detected magnetic resonance, researchers demonstrated that mixed-cation MAFAPbI perovskite single crystals host distinct electron and hole spin subensembles with millisecond-long relaxation times at cryogenic temperatures, establishing them as a promising solid-state platform for quantum information applications.
This study demonstrates that the excitonic Mott transition can occur without population inversion in monolayer transition metal dichalcogenides under ultrafast non-equilibrium excitation, driven by the interplay of nonthermal carrier populations and nonequilibrium dynamical screening rather than conventional quasi-equilibrium mechanisms.
This paper introduces a tensor-network method with a jump-counting estimator that efficiently simulates steady-state electron transport in interacting quantum-dot arrays of up to 50 dots, offering significant computational advantages over traditional density-matrix solvers while maintaining quantitative agreement with state-of-the-art benchmarks.
Using vectorial spin-polarized scanning tunneling microscopy, this study provides microscopic evidence of spin-driven multiferroicity in monolayer NiI2 by identifying a canted spin-spiral state and topological meron/antimeron pairs at domain walls, which are explained by a realistic spin model incorporating Kitaev interactions and establish a platform for electric-field control of topological textures.
This paper extends the application of test particle sum rules to optimize the free parameters in the Lutsko formulation of White-Bear and White-Bear mark II fundamental measure theory functionals, resulting in more accurate and consistent classical density functionals for hard-sphere fluids.
This perspective paper reviews recent theoretical, numerical, and experimental advances demonstrating that topological defects, traditionally used to explain crystalline properties, also provide a fundamental framework for understanding the mechanical response and complex dynamics of amorphous solids, while highlighting key open questions and future research directions.
This paper demonstrates that complete coherent control of single spin qubits in self-assembled InAs quantum dots can be achieved under oblique magnetic fields, offering a tunable spin-mixing regime that relaxes alignment constraints compared to conventional Voigt geometry.
This paper proposes a general mechanism where intrinsic atomic spin-orbit coupling gaps a symmetry-protected quadratic band crossing point, thereby shielding the resulting topological gap from competing instabilities and identifying monolayer compounds as realistic candidates for robust quantum anomalous Hall phases at elevated temperatures.
This paper reports the first experimental observation and deliberate engineering of the elusive ferromagnetic Kondo effect in a triangulene dimer molecular system, where low-temperature scanning tunneling spectroscopy and many-body calculations confirm the coexistence of ferromagnetic and overscreened Kondo regimes exhibiting singular Fermi-liquid behavior.
