This study reports the first observation of a thermodynamically stable exciton crystal in a tunable moiré excitonic insulator, evidenced by optical Umklapp scattering and transport resistance peaks at one exciton per three moiré sites, thereby establishing a versatile platform for exploring correlated bosonic and fermionic phases.
This paper introduces a polymer-free fabrication method to successfully isolate and image air-sensitive 2D transition metal di-iodides at the monolayer limit, revealing their unique structural characteristics, including low-energy stacking barriers and stable iodine vacancies, while demonstrating a versatile platform for creating clean suspended van der Waals heterostructures.
This study utilizes ultra-low-power surface acoustic waves to demonstrate that ultra-high-mobility two-dimensional electron systems exhibit increased incompressibility when subjected to perturbative currents, challenging the common assumption that quantum phases remain unchanged under such conditions.
By employing orders of magnitude lower Surface Acoustic Wave (SAW) amplitudes than in previous studies, this research reveals an anomalously large SAW attenuation in the quantum Hall regime that contradicts the conventional relaxation model and only manifests at sufficiently low power levels.
This study utilizes real-space imaging to demonstrate that strain engineering can tune the size of uniform moiré domains in helical trilayer graphene, revealing enhanced conductance at domain boundaries and offering a pathway to design correlated topological networks at the supermoiré scale.
This paper attributes the unexpected nonzero Josephson currents observed in topological insulator junctions at integer fluxoid states to junction imperfections rather than Majorana zero modes, proposing that low-energy bound states arising from irregularities drive the current and suggesting microwave spectroscopy as a method to experimentally verify this mechanism through distinctive vortex transition selection rules.
Through large-scale microscopic calculations of up to 900 composite fermions, this study reveals that the static structure factor of composite-fermion metals exhibits a dependence rather than the theoretically predicted term, a behavior accurately captured by a model of a non-interacting Fermi sea of dipolar composite fermions.
This paper presents a unified classical and quantum theory of coupled spin and acoustic wave dynamics in continuum magnetic films, deriving equations of motion that incorporate magnonic nonlinearity and magnetoelastic interactions to explain phonon-to-magnon down-conversion and enable acoustic control of magnons in the quantum regime.
This paper proposes a theoretical model demonstrating that a metallic ferromagnet with noncollinear antiferromagnetic order can exhibit an anomalous Hall effect and spin-momentum locking without intrinsic spin-orbit coupling, driven by a tunneling-based interaction between conducting fermions and localized spins.
This paper theoretically demonstrates that Néel-ordered collinear antiferromagnets can exhibit an anomalous Hall effect through the interplay of momentum-dependent exchange interactions and spin-orbit coupling, a phenomenon governed by broken symmetries that allow for Dzyaloshinskii's invariants and spontaneous weak magnetization.
