This paper presents a spectroscopy technique that directly maps the energy level structure of silicon double quantum dots, revealing the transition from atomic to molecular states and resolving spin-valley splittings across one- and two-electron regimes.
This study reveals the existence of both flat and newly discovered zig-zag interphase boundaries in compressively strained bismuth ferrite thin films, characterizing their atomic-scale structural features and suggesting that mesoscale strain modulations drive their formation for potential device engineering.
This paper establishes a generalized doubling theorem for -fold exceptional points in both linear and nonlinear systems by introducing frequency-momentum winding numbers as new topological invariants that characterize their topology across the Brillouin zone and reveal a previously unreported topology for $PT$-symmetric two-fold exceptional points.
This paper demonstrates that graphene Josephson junctions exhibit a strong, gate-tunable photoresponse at terahertz frequencies with ultra-high responsivity and noise-equivalent power, establishing them as a promising platform for broadband quantum sensing and potential single-photon detection above millikelvin temperatures.
This paper demonstrates that radio-frequency excitation reshapes the mesoscale charge-density-wave landscape in 1T-TaS2 thin films by annealing frustrated domains and reorganizing discommensuration networks, thereby enabling precise control over collective electron-phonon order and metastable transport states for applications in reconfigurable electronics and unconventional computing.
This paper introduces depth-resolved electron diffraction imaging (DREDI), a rapid and non-destructive technique that maps three-dimensional polarization textures across six orders of magnitude in length scale, revealing how surface stripe domains in epitaxial BiFeO₃ films evolve into buried flux-closure vortices and mesoscale percolating networks driven by strain heterogeneity.
This paper presents a theory of electronic Raman scattering in 2D metals with broken inversion symmetry, demonstrating that the resulting spin-photon interaction enables the detection of spin excitations without resonance tuning and revealing distinct, significantly stronger spectral signatures in doped graphene compared to conventional 2D electron gases due to the large Dirac velocity.
This paper presents a scalable method for fabricating arrays of lipid-sealed femtoliter microwells integrated with organic electrochemical transistors, enabling the simultaneous electrical and optical detection of membrane protein activity by monitoring ion flux and dye diffusion through embedded -hemolysin pores.
This study combines high-quality transport experiments with ab initio calculations to demonstrate that remote scattering from hBN's out-of-plane phonons, rather than intrinsic graphene phonons or higher-energy modes, fundamentally limits the electrical resistivity of hBN-encapsulated graphene, particularly at low carrier densities and temperatures between 150 K and room temperature.
This paper proposes the in-plane 2D polarizability () as an unambiguous metric to characterize the dielectric response of nanoconfined water, overcoming the ambiguity of traditional width-dependent definitions through consistent molecular dynamics simulations.
