This paper establishes a symmetry-protected correspondence between the band topology of coherent Hamiltonians and the spectral winding of open quantum systems, demonstrating that Hamiltonian topology can actively control Liouvillian topological phases, the skin effect, and non-equilibrium dynamics in dissipative lattices.
This paper proposes a mechanism to realize the excitonic quantum anomalous Hall effect in collinear magnets without spin-orbit coupling by utilizing electron-phonon coupling to induce noncollinear spin textures via triplet exciton condensation, identifying bilayer V2SeTeO as a promising candidate material.
This paper presents a first-principles theoretical framework for qubit measurement and backaction in multimode nonreciprocal systems, which successfully predicts experimental results for an integrated three-mode readout device and forecasts high efficiency for its operation as a nonreciprocal amplifier.
This paper demonstrates that electronic states in supertwisted multilayer spirals undergo a universal transition from extended 3D to localized 2D behavior as in-plane momentum increases beyond a critical threshold, a phenomenon explained via the Aubry-André model and supported by predicted transport signatures.
This paper introduces a new class of coplanar antiferromagnets that exhibit parity and time-reversal invariant Ising spin ordering, demonstrating that their spin-rotational symmetry breaking enables unique non-relativistic spin transport phenomena and tunable spin splittings, with sixteen candidate materials identified to validate these emergent responses.
This paper proposes a theoretical framework for generating zero-field superconducting vortices and pinning Majorana zero modes in correlated Rashba systems by leveraging the inhomogeneous magnetization gradients induced by exchange-coupled magnetic islands, offering a viable experimental route to trap these composite excitations without external magnetic fields.
The authors report that a tantalum-based transmon qubit exhibits exceptional stability with a charge offset pinned at zero for nearly three months due to a fragile, inadvertently formed parallel superconducting layer caused by incomplete etching, offering a potential route to eliminating charge-offset drift in superconducting circuits.
This paper presents a novel, tunable, and shape-preserving method for converting microwave frequencies in superconducting circuits by utilizing a dynamic Doppler effect induced by a propagating phase-velocity front, which offers advantages over conventional mixing techniques such as the absence of spurious products and the ability to imprint arbitrary frequency patterns.
This paper demonstrates a hybrid device using a quantum dot embedded in a nanowire to bridge a curved waveguide, enabling the efficient evanescent coupling and collection of single photons from various excitonic complexes at multiple output facets to pave the way for multi-directional on-chip quantum integration.
This study experimentally demonstrates the annihilation of Dirac points in a photonic Kagome lattice and the associated topological obstruction, revealing how non-Abelian frame rotations and quaternionic charge conversions govern the transition between different topological phases characterized by the Euler number.
