This paper demonstrates a high-fidelity experimental mapping between an electron spin state and the polarization of a reflected photon in a quantum dot-cavity system, achieving a 95% fidelity projection of the spin state with a single photon detection and paving the way for deterministic optical quantum logic gates.
This study demonstrates that the quantum coherence of strongly anisotropic non-Kramers Tb spins in CaWO is uniquely sensitive to mechanical angular fluctuations, revealing a previously overlooked decoherence pathway that can be exploited to create a high-precision spin-based angular probe.
This paper develops a semiclassical theory demonstrating that disorder-induced asymmetric scattering mechanisms, which require broken time-reversal symmetry, can significantly enhance the orbital Edelstein effect in magnetized Rashba systems, potentially yielding orbital magnetization an order of magnitude larger than spin magnetization.
This paper introduces the HyperDet wavefunction, a phase-agnostic variational ansatz that fuses auxiliary fermionic partons via a learnable fusion tensor to accurately describe diverse strongly correlated phases and extract their underlying topological and symmetry properties without requiring prior knowledge of specific order parameters.
This paper establishes a unified wavefunction framework for anyon superconductivity by constructing hierarchy-based states from various parent topological orders, characterizing their key physical properties through plasma and field-theoretic analogies, and demonstrating their natural emergence in dilute limits relevant to ideal Chern and moiré bands.
This paper demonstrates that the triangular kagome lattice hosts a rich topological magnon band structure with high Chern numbers and unique ferrimagnetic ground states, enabling significant thermal Hall effects and a nonzero Einstein-de Haas effect that positions the system as a promising platform for quantum magnonics applications.
This paper investigates topological magnons on an anisotropic square-hexagon-octagon lattice derived from a biphenylene network, proposing a DMI-free mechanism for type-II Dirac points and Dirac nodal loops characterized by invariants, while analyzing their topological phase transitions, chiral edge modes, and associated thermal Hall and Einstein-de Haas effects.
Using spectroscopic scanning tunneling microscopy at 0.3 K, researchers discovered that the spinel superconductor LiTi2O4 hosts triangular Abrikosov vortices with orientations locked to crystallographic domains rather than the magnetic field, providing evidence for a hidden chiral selectivity in its multicomponent order parameter.
This paper proposes a honeycomb lattice model of collinear altermagnets that hosts Weyl and nodal-line magnons without Dzyaloshinskii-Moriya interaction, characterized by chirality and topological invariants, which give rise to observable phenomena such as the magnon spin Nernst effect and a topology-induced differential gyromagnetic ratio detectable via the Einstein-de Haas effect.
This paper proposes bicircular Raman spectroscopy as a universal optical probe to identify altermagnetic magnons by detecting their momentum-dependent chirality and enhanced nonlinear light-magnon interactions, thereby distinguishing altermagnets from antiferromagnets regardless of the underlying magnon topology.
