This paper demonstrates a lithographic approach using a patterned graphene gate on monolayer MoSe2 to stabilize and dynamically tune Wigner crystals at significantly higher temperatures and densities than previously possible, transforming them from fragile static phases into reconfigurable quantum matter.
This paper proposes linear magnetoresistance with butterfly-like hysteresis as a robust, symmetry-independent transport signature for detecting altermagnets and their Néel vectors, offering a critical alternative to the anomalous Hall effect which often vanishes in these materials.
This study reports the first direct experimental observation of a hybridization-wave electronic order in the van der Waals Kondo lattice material 6R-TaS2, where scanning tunneling microscopy reveals a symmetry-breaking, unit-cell-doubling modulation of the hybridization gap that correlates with an intertwined nematic order.
This paper theoretically demonstrates that a constant source-drain voltage applied to a carbon nanotube quantum dot with antiparallel half-metallic ferromagnetic electrodes can drive detectable torsional vibrations through spin-rotation coupling, particularly when Zeeman splitting resonates with the torsional phonon energy.
This paper investigates the microscopic mechanism of zero-bias currents induced by injected phonons in metals and one-dimensional charge density wave systems on piezoelectric substrates, demonstrating how propagating phonons break inversion symmetry to generate currents via deformation and piezoelectric potentials, with distinct behaviors observed below the CDW transition temperature.
This study investigates magnetic-field-induced magnon excitations in the van der Waals antiferromagnet CrOCl, revealing how competing exchange interactions and anisotropies drive complex phase transitions that generate diverse magnonic spectra and spatially separated magnetic phases.
This paper generalizes the phenomenon of dynamic charge oscillations in quantum conductors driven by ultrashort voltage pulses beyond interferometric systems, demonstrating that these oscillations persist in generic non-interferometric setups like fractional quantum Hall quantum point contacts due to sublinear DC current characteristics and remain robust even in the presence of strong Coulomb interactions.
This paper proposes a novel, high-fidelity two-qubit controlled-Z gate protocol for Germanium hole spin qubits that leverages anisotropic exchange interaction and composite electrical baseband pulses to suppress dephasing from charge noise, thereby advancing the path toward fault-tolerant semiconductor quantum processors.
This study utilizes MHz-frequency STM noise spectroscopy to reveal that the ionization of individual sulfur donors in InAs is a dynamic, non-equilibrium process driven by local electric fields, characterized by nanosecond-scale charge-state switching and a distinct bias-dependent onset linked to bulk electron interactions.
This paper generalizes the topological lower bound on quantum weight beyond symmetry-protected topological phases by introducing a symmetry-breaking correction, demonstrating that the bound remains valid even when underlying symmetries are broken, as illustrated in a spin Chern insulator model with nonzero spin-orbit coupling.
