This study demonstrates that electrically driven Loss-DiVincenzo spin qubits exhibit a linear Rabi frequency scaling with microwave drive amplitude even under simultaneous multi-qubit driving, thereby refuting the notion that previously observed nonlinearities are a general characteristic of such systems.
This paper experimentally demonstrates and theoretically models nonlinear mode coupling in high-stress silicon nitride membrane resonators, revealing how tension-mediated geometric nonlinearity and mode symmetry govern intermodal interactions to enable controllable multimode frequency tuning.
Using scanning tunneling microscopy, researchers discovered that YbB exhibits coexisting conducting and insulating surface domains with distinct atomic terminations and band-bending, where the insulating regions disprove its status as a strong topological insulator while the spin-polarized conducting regions suggest potential for spintronic applications.
This paper presents a general first-principles framework based on Legendre transforms to control local spin moments at the linear-response level, enabling accurate calculation of dynamical properties in noncollinear magnets and revealing electron-inertia-induced mass renormalizations in the THz optical response of CrI and CrO.
This paper reports the observation of Dirac Landau polaritons in HgTe quantum wells via strong coupling between 2D Dirac fermion cyclotron transitions and cavity modes, demonstrating efficient nonlinear terahertz electroluminescence under electrical injection that suggests the onset of stimulated emission and paves the way for low-threshold, tunable THz polariton lasers.
This paper systematically derives a dissipationless quantum kinetic equation for multi-band free fermionic systems using the Moyal product formalism to fully band-diagonalize dynamics and analyze second-order gradient corrections, revealing the critical role of quantum geometric tensors in band-resolved thermodynamics, nonlinear transport, and density-density response functions.
This paper analytically and numerically demonstrates that a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals is spectrally equivalent to a simpler side-coupled system, revealing how geometric factors and side-mode competition govern Andreev bound state spectra and induce a Josephson diode effect.
This study provides both theoretical and experimental evidence that polariton-like behavior can emerge in a two-dimensional exciton-cavity system by crossing an exceptional point, demonstrating that such effects occur even when the conventional strong coupling condition is not met.
This paper predicts that exciting magnons in a disordered antiferromagnetic Josephson junction significantly enhances the stationary supercurrent across long junctions, offering a promising mechanism for superconducting spintronics applications.
This paper demonstrates high-fidelity (99.8%) bucket-brigade spin shuttling in a silicon MOS device and reveals that residual errors are highly sensitive to the ratio between interdot tunnel coupling and Zeeman splitting, a relationship validated by a four-level Hamiltonian model to guide future quantum architecture optimization.
