This paper extends the Shockley-Queisser limit to nanostructured solar cells using a quantum phase space formalism to demonstrate that quantum confinement in specific geometries, such as 3-nanometer spheres and 5-nanometer cubes, can theoretically boost maximum efficiency to approximately 49.1%, significantly surpassing both bulk material performance and classical limits.
This paper proposes a self-calibrating thermal interferometry scheme in a two-dimensional chiral superconductor that utilizes a reconfigurable domain wall to simultaneously measure the integer count of chiral Majorana modes via quantized thermal conductance and detect the parity of enclosed vortices through Fabry–Pérot resonance shifts in a closed configuration.
This paper proposes and theoretically models a novel spintronic memcapacitor based on altermagnetic multiferroic rare-earth vanadates (RVO), which exhibits simultaneous, non-volatile charge and spin switching with high current efficiency and a distinctive "butterfly" differential capacitance under an oscillating electric field.
This paper introduces AARDVARK, an unsupervised machine learning framework that combines UMAP dimensionality reduction with Gaussian process regression to enable efficient, real-time, and autonomous identification of electronic and chemical phases in spatially-resolved photoemission spectroscopy experiments.
This paper reports the discovery of twisted magnon frequency combs in ferromagnetic nanorings, demonstrating how their formation, mode density, and tunable spacing can be precisely controlled through geometric hole size and external magnetic fields via nonlinear coupling and angular momentum conservation.
This paper demonstrates that cubic Dresselhaus orbital coupling generates momentum-space hot spots and a significantly enhanced divergence coefficient, boosting the intrinsic orbital Hall conductivity by over an order of magnitude compared to linear Rashba-type coupling to enable giant orbital Hall responses.
This paper proposes and analyzes a novel platform for Majorana zero modes consisting of a quantum dot chain sandwiched between an s-wave superconductor and a spin-orbit semiconductor, demonstrating that the zero-energy retarded Green function effectively maps the system's topological phase diagram and spatial wave function characteristics in agreement with transfer matrix results.
This paper presents organic transistors embedded with sub-nanometer platinum nanoparticles at an ultrathin oxide interface that exhibit a large memory window, Coulomb blockade-like transport, and enhanced short-term plasticity, offering a promising platform for neuromorphic computing.
This paper demonstrates that AB-stacked MoTe/WSe heterobilayers at a specific hole doping can host topological Kondo semimetal and insulator ground states driven by chiral Kondo coupling between a Mott-localized MoTe layer and itinerant WSe electrons, with the latter state being stabilizable by random strain fields to achieve a quantized spin Hall effect.
This paper theoretically demonstrates that a classical bosonic mode, such as a magnon in an antiferromagnet or a phonon, can serve as a superior probe for resolving magnonic number states via effective dispersive couplings, outperforming traditional superconducting qubit sensors.
