By utilizing superconducting scanning tunneling microscopy with manganese-functionalized tips to avoid ferromagnetic electrodes, this study provides unambiguous experimental evidence that single enantiomers of heptahelicene act as effective spin polarizers, confirming the chirality-induced spin selectivity effect and ruling out electrostatic artifacts.
This study demonstrates a novel method for achieving ultra-efficient trion emission in intrinsic, defect-free semiconductors by transferring charged excitons from two-dimensional tungsten-diselenide donors to one-dimensional carbon-nanotube acceptors, thereby overcoming conventional doping requirements and Auger-quenching limitations to boost emission efficiency by over 100-fold.
This paper proposes a non-invasive, multiparametric liquid sensing platform that utilizes DNA-tethered magnetic nanoparticles as nanoscale mechanical oscillators to modulate the magnetic fields detected by nitrogen-vacancy centers in diamond, enabling high-dimensional characterization of liquid properties through spatially patterned surface functionalization.
This paper demonstrates that ultra-scaled monolayer and bilayer molybdenum disulfide nanoribbon transistors can overcome the conventional width-scaling bottleneck by achieving enhanced on-current density and superior electrostatic control at channel widths as narrow as 15 nm.
This paper proposes that dynamical axion-polaritons, formed by the coupling of magnetic fluctuations and electromagnetic fields, can exhibit perfect nonreciprocity under static external fields, effectively functioning as an optical isolator where light propagates in one direction while being completely decoupled in the opposite direction.
This paper employs a particle-number-conserving effective model and advanced computational methods, including neural-network quantum states, to characterize the distinct superconducting, correlated, and critical regimes of quantum dot clusters coupled to a common superconductor, revealing dimension-dependent ground state behaviors such as gapless transitions in one dimension and robust triplet states in two dimensions.
This study reports the observation of long-lived dipolar interlayer excitons in a MoSSe/MoSe heterobilayer, demonstrating their potential as a versatile platform for engineering and tuning excitonic interactions in van der Waals materials.
This paper develops a rigorous two-scale analytical framework to model heat generation and transport in nanomagnet chains, demonstrating that realistic magnetic hyperthermia systems operate in a collective heating regime where local temperature variations are negligible (K) due to the dominance of macroscopic diffusion over nanoscale losses.
This paper investigates anomalous transport in equilibrium fermionic fluids coupled to Weyl-type nonmetricity, utilizing a formal descent analysis and transgression techniques to derive constitutive relations that reveal nonmetricity-mediated chiral separation effects driven by fluid vorticity and the Weyl magnetic field.
This paper theoretically investigates the Coulomb-mediated interactions of charge-transfer excitons in TMD lateral heterostructures, revealing a net energy blueshift and a quadratic dipole-moment dependence in energy renormalization that distinguishes them from vertical heterostructures, while identifying spatial energy offset and temperature as key control parameters.
