This paper predicts a novel dynamical proximity effect in topological superconductor/ferromagnetic insulator heterostructures where spin-momentum locking facilitates the coupling of ferromagnetic magnons and superconducting Nambu-Goldstone modes into hybrid excitations, enabling the interconversion of spin and spinless signals for advanced superconducting spintronics.
This paper demonstrates that odd-parity antiferromagnets, despite their potential for spintronics applications, are inherently prone to incommensurate magnetic ordering due to symmetry-allowed Lifshitz invariants and van Hove singularities, often resulting in first-order transitions or intermediate incommensurate phases.
This paper presents a continuous-wave, high-resolution, ultra-broadband mid-infrared nonlinear spectroscopy platform utilizing tunable dual-resonant plasmonic nanocavities to enable scalable, chip-level, label-free sensing and single-molecule studies through coherent vibrational sum- and difference-frequency generation under ambient conditions.
This paper demonstrates that breaking conservation laws in system-environment interactions creates competing nonequilibrium dissipation channels that, when combined with long-range environmental correlations, enable the generation of steady-state entanglement in thermal environments without the need for fine-tuned coherent control.
This paper proposes a robust quantum metrology device based on a modified fermionic Wheatstone bridge that utilizes geometric asymmetry and current circulation reversal near an additional energy degeneracy point to precisely detect unknown hopping rates, even under moderate environmental noise and varying operating conditions.
This theoretical study demonstrates that terahertz radiation can induce transitions between attractive and repulsive Fermi polaron states in transition metal dichalcogenide monolayers through both a direct optical conversion process governed by many-body correlations and an indirect mechanism driven by electron gas heating.
Through systematic experiments on Josephson junctions in a true resistive environment, this study resolves the long-standing debate on the Schmid-Bulgadaev transition by confirming that the crossover from superconducting to insulating behavior occurs at the theoretically predicted quantum resistance of , even at non-zero temperatures.
This paper proposes a method to generate magnon squeezed states in a hybrid cavity-magnon-qubit system by engineering an effective Rabi-type interaction and operating near a ground-state superradiant quantum critical point, demonstrating that moderate squeezing is achievable with current experimental parameters despite dissipation and thermal noise.
This review paper outlines the theoretical framework and experimental progress of microwave-to-optical quantum transduction, a critical technology for connecting superconducting quantum computers into large-scale networks, by analyzing various conversion methods such as optomechanical, electro-optic, magneto-optic, and atomic ensemble approaches.
This study demonstrates the direct generation of Purcell-enhanced single photons in Laguerre-Gaussian modes carrying orbital angular momentum by integrating individual CsPbBr quantum dots into a tunable open Fabry-Perot microcavity with a nanofabricated deformation.
