This paper presents a generic formulation for the quantum geometric dipole (QGD) of collective excitations in many-body electron systems that relies on the density matrix rather than specific single-particle wavefunctions, demonstrating its validity and intrinsic nature across both integer and fractional quantum Hall states.
This study reveals that lattice reconstruction in twisted MoSe₂ homobilayers induces a novel "charge-transfer" trion resonance, where spatially separated electron-hole pairs and doped holes emerge due to distinct moiré potentials acting on different valleys and sites within the superlattice.
This paper elucidates the mechanism behind polar skyrmions in (PbTiO)/(SrTiO) superlattices by demonstrating that the coupling between electric polarization and strain drives the formation of layer-dependent Neel-to-Bloch skyrmion structures with unique topological numbers.
This paper reports spin polarization measurements in GaAs quantum Hall states for filling factors between 1 and 2 using microcavity polaritons, revealing full polarization at v=1 with Skyrmion-induced depolarization, and observing depolarization and repolarization at fractional states that align remarkably with a non-interacting, disorder-free Composite Fermion model.
This paper establishes a direct correspondence between quantum Autler-Townes splitting and parametric normal mode splitting in classical coupled oscillators, experimentally demonstrating both fundamental and second-subharmonic splitting in a nanomechanical system to enable quantitative extraction of modal coupling.
The authors experimentally demonstrate a scalable, low-overhead on-chip coupler that utilizes a binary-tree mapping to achieve exponentially enhanced connectivity and high-fidelity non-local entanglement between fluxonium qubits, thereby enabling the implementation of efficient quantum error correction codes like qLDPC on superconducting devices.
This study establishes the FeDy molecular ring as a viable platform for the direct preparation, accumulation, and detection of finite-temperature toroidal polarization by combining an ab initio-informed theoretical framework with a novel protocol utilizing temporally asymmetric near-infrared waveforms and magnetoelectric coupling.
This study demonstrates that an out-of-plane electric field can induce dominant spin splitting in the Q and Q' valleys of multilayer n-type WSe2 via spin-valley-layer coupling, offering a powerful non-magnetic alternative to magnetic fields for controlling spin states in low-power spintronic and quantum devices.
This paper presents a novel microscopic theory explaining that low-temperature microwave dissipation in strongly disordered superconductors is dominated by bulk localized collective modes arising from spatial inhomogeneity, thereby resolving the limitations of standard Mattis-Bardeen theory and offering strategies to mitigate losses in superconducting quantum devices.
By employing a refined gating protocol to map a complete, symmetric superconducting dome in ionic liquid-gated MoS₂, this study reveals an anticorrelation between superconductivity and non-Fermi liquid behavior in the normal state, where scattering rates reach the Planckian limit, thereby offering new insights into the emergence of superconductivity in transition metal dichalcogenides.
