This paper reports the direct experimental observation of a strongly nonlinear transport regime in a high-mobility two-dimensional electron system, where a Venturi-shaped device geometry reveals a pronounced voltage response and diodicity consistent with the convective acceleration of an electron fluid described by the Bernoulli effect.
This paper proposes a three-path fractional quantum Hall interferometer that utilizes cubic Aharonov-Bohm harmonics and specific voltage orderings to independently resolve downstream and upstream propagation, thereby enabling the separate extraction of quasiparticle charge, scaling dimension, and exchange angle to test edge chirality.
This paper demonstrates that hyperbolic polariton condensates realize an indefinite Bogoliubov metric that transforms the standard acoustic light cone into a hyperbolic stability wedge, organizing non-Hermitian exceptional degeneracies into an "exceptional cone" that separates propagating quasiparticles from dynamically unstable ones.
This paper presents a generalized nucleation theory that incorporates edge-induced line tension to derive a closed-form expression for nanopore activation, revealing how geometric confinement and interfacial asymmetry significantly reshape nucleation energy landscapes and offer new strategies for controlling phase transitions in nanoscale environments.
This paper proposes a feasible protocol to measure von Neumann entropy and mutual information in complex, interacting quantum transport systems by leveraging the persistent connection between entanglement and two-point correlation functions, even under realistic conditions like boundary interactions and quantum quenches.
This paper presents a machine learning methodology that successfully predicts the Hubbard U parameter from scanning tunneling microscopy images of twisted bilayer graphene, demonstrating robustness against experimental noise and revealing interaction-dependent spectral weight redistribution.
This paper demonstrates that transverse-electric/transverse-magnetic splitting in dielectric-mirror microcavities induces spin-momentum locking in honeycomb exciton-polariton edge states, enabling ultrafast, unidirectional, spin-controlled propagation without external magnetic fields.
This paper establishes a theoretical framework linking the symmetry-enforced zeros of electronic wavefunctions at high-symmetry momenta to band topology, enabling the direct experimental determination of topological invariants via scanning tunnelling microscopy and providing insights into interaction effects in correlated materials.
This paper demonstrates that ultrastrong coupling between a nanotube mechanical oscillator and a double-quantum-dot electronic system enables a tunable, record-high mechanical nonlinearity at the zero-point motion scale alongside a gate-controllable nonlinear continuous readout.
This study demonstrates the direct current-induced creation and manipulation of embedded magnetic skyrmion bags in FeGe nanoplates under zero magnetic field, revealing a spin-transfer-torque-driven mechanism that enables electrical control over complex topological structures like magnetic monopoles and bobbers for future spintronic applications.
