This paper demonstrates that energy-space entanglement entropy in quantum impurity models exhibits universal behavior at Fermi-liquid fixed points, where it converges to constants determined by topological edge modes, and reveals distinct entanglement signatures and universality classes across transitions between local-singlet, Kondo-singlet, and non-Fermi-liquid phases.
This paper presents a highly sensitive, wireless magnetoelastic humidity sensor functionalized with a PEDOT:PSS coating that achieves superior sensitivity and resolution by leveraging humidity-induced structural swelling and mass loading effects.
This paper investigates phase noise in VO-based relaxation oscillators, identifying thermal fluctuations during the incubation phase as the primary cause of spectral linewidth broadening at low frequencies and demonstrating that synchronization with an external square-wave signal offers superior phase noise suppression compared to sinusoidal injection locking.
This paper reports the first thermodynamic measurement of entropy suppression during Kondo singlet formation in a GaAs quantum dot, demonstrating that temperature-dependent charge sensing reveals an asymmetric lineshape characteristic of Kondo screening that aligns qualitatively with numerical renormalization group calculations.
This paper reports the observation of substantial third-order nonlinear transport in a trilayer 1T'-MoTe superconductor within its percolative transition regime, demonstrating that the resulting third-harmonic voltage serves as a sensitive probe of superconducting fluctuations arising from coexisting normal electrons and Cooper pairs.
This paper demonstrates that fractional Chern insulator states can emerge in kagome magnets with noncoplanar magnetic order, where stronger electron-electron interactions relative to band dispersion stabilize these states over a broader range of scalar spin chirality.
This study combines scanning tunneling microscopy and density functional theory to reveal that single phosphorus atoms incorporate into the Si(100) surface via an exchange mechanism with a silicon atom, forming a stable P-Si-Br complex upon annealing at temperatures as low as 175°C.
This study demonstrates that inserting an Ag spacer between epitaxial Bi and ferromagnets preserves Bi's structural integrity, thereby enhancing charge-to-spin conversion efficiency by over an order of magnitude and confirming that the dominant mechanism is bulk spin-orbit coupling rather than interfacial Rashba effects.
This paper presents a novel current-mode charge sensor implemented in a suspended carbon nanotube that achieves state-of-the-art charge sensitivity and high-fidelity single-shot readout of a double quantum dot, overcoming the design constraints of traditional impedance-matched or proximity-based detection methods.
This study reports the successful growth of epitaxial -MnTe thin films on InP(111) substrates and demonstrates, through combined magneto-transport measurements and DFT calculations, that interface-induced symmetry breaking and point defects can induce a finite net magnetic polarization in this altermagnetic candidate, offering a pathway for engineering magnetic responses in spin-based electronics.
