This paper introduces a method to derive general lower bounds on relaxation and second-order correlation times using only steady-state expectation values and their derivatives, enabling the characterization of ultrafast dynamics and complex many-body systems without requiring full time-evolution calculations.
Using low-temperature Scanning Tunneling Microscopy, this study confirms robust two-dimensional surface superconductivity in the Weyl semimetal -PtBi by directly observing quantized vortices and the Josephson effect, thereby establishing macroscopic quantum phase coherence linked to Fermi arcs.
This paper presents a graphene-enabled, on-chip integrated detector-interferometer that achieves record-high responsivity and phase-sensitive (sub-)terahertz detection, enabling deep sub-wavelength thickness measurements of thin films for diverse industrial applications.
This paper demonstrates that realistic imperfections, such as pairing asymmetries and magnetic disorder, in proximitized double helical liquids enrich the topological landscape by inducing a cascade of phase transitions, the revival of Majorana zero modes, and a novel topological superconducting regime where disorder acts as a tunable parameter rather than a detrimental factor.
This study demonstrates a radical reconfiguration strategy that transforms a single-radical aza-triangulene into a topologically protected, frustrated spin trimer with tunable interactions and non-interacting edge spins, effectively creating a molecular analog of a three-qubit quantum register.
This paper introduces Replica Scanning Tunneling Microscopy (R-STM), a novel method that leverages periodic replica signals to efficiently bridge atomic and mesoscopic length scales, enabling the visualization of atomic-scale superconducting gap modulations over micron-sized areas in materials like UTe and FeSe.
This study characterizes the magneto-optical response of epitaxial -based Heusler thin films using MOKE and BLS, revealing that while exhibits a distinct wavelength-dependent quadratic signal and strong BLS intensity at 457 nm, other compositions respond dominantly linearly, thereby guiding the optimal probing wavelength for these materials.
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.
