This theoretical study demonstrates that coupling Majorana bound states in a superconductor-semiconductor heterostructure to a photonic cavity modifies the effective superconducting pairing, thereby shifting the topological phase boundary to lower Zeeman energies while suppressing the pairing at strong coupling strengths.
This paper demonstrates that conical intersections in the quasienergy spectrum of a driven two-level system carry quantized topological charges determined by hidden time-nonlocal symmetries and driving amplitude parity, and proposes experimental protocols to isolate and directly observe these geometric phases.
This study identifies exchange striction—the sensitivity of exchange coupling to atomic displacements—as the key material parameter determining the ultrafast demagnetization speed of antiferromagnetic insulators, enabling the prediction and screening of candidate materials for high-speed memory applications.
This paper employs an atomistic framework to demonstrate that interfacial orbital torques are the primary mechanism driving the efficient excitation of exchange-dominated terahertz magnons in nanoscale ferromagnets, resolving the microscopic origins of mode-selective excitation observed in recent experiments.
This study utilizes excitation-energy-dependent photoluminescence excitation spectroscopy to demonstrate that resonant excitation drives dipolar interlayer excitons in MoSe/WSe heterobilayers into a nonlinear, high-density regime characterized by emission saturation and a population-dependent blueshift, providing direct evidence of net repulsive exciton-exciton interactions dominated by dipole-dipole forces.
This paper introduces "geometronics," a concept demonstrating how substrate topography can locally reorient anisotropic van der Waals crystals to transform uniform external perturbations into programmable, switchable magnetic and electronic landscapes without altering the material's composition.
This paper demonstrates that Shubnikov-de Haas oscillations, analyzed with a method that accounts for superconducting shunting, can successfully characterize the normal-state electronic parameters of buried semiconductor quantum wells beneath various superconducting films, revealing that while interface subbands form, the intrinsic properties of the underlying well remain largely unchanged and its quantum lifetime is preserved or enhanced.
This paper demonstrates that, unlike in bulk 3D superconductors, the lower critical field for vortex formation in 2D superconductors is inherently size-dependent, scaling inversely with the sample area and revealing a singular thermodynamic ground state where the zero-field limit depends critically on the trajectory of approach in the plane.
This paper develops a boundary-subspace description for topological state transfer in superconducting-qubit Rice-Mele chains, demonstrating that projecting onto localized edge modes yields an effective few-level Hamiltonian that enables high-fidelity transport and reveals how splitting the chain at a shared boundary accelerates the transfer process compared to a single uninterrupted chain.
This paper proposes a universal set of quantum gates for hybrid qubits formed by coupling quantum dot spin qubits to parafermions, utilizing Fock parafermions to clarify the role of particle-hole symmetry and outlining experimental realizations and readout schemes for and systems.
