This paper presents a "waterless" conductive atomic force microscope lithography technique compatible with vacuum and cryogenic environments that enables the creation of nonvolatile, reconfigurable oxide nanoelectronics with 0.85 nm resolution at millikelvin temperatures by engineering oxygen vacancies to control interfacial polaron-electron liquid transitions.
This paper proposes a scheme where a giant atom, realized by a qubit nonlocally coupled to a honeycomb lattice of resonators, can selectively emit valley-polarized photons and achieve disorder-robust chiral emission along domain walls without breaking time-reversal symmetry.
Using density matrix renormalization group methods, this paper refutes the claim of a universally protected intrinsic electric dipole moment at fractional quantum Hall edges, demonstrating that such a value is realized only in the state but not in other systems like or Pfaffian-anti-Pfaffian interfaces.
This paper develops a unified nonadiabatic theory for phonon magnetic moments in both insulators and metals using a gauge-covariant Wigner expansion, which successfully explains the experimentally observed large magnetic moments in PbSnTe by revealing significant contributions from Fermi-surface processes and resonant interband transitions beyond the adiabatic limit.
This paper demonstrates that combining uniaxial strain with off-resonant circularly polarized light in graphene drives the system into a Floquet second-order topological insulator phase, characterized by gapped edges and robust in-gap corner modes, thereby establishing strained graphene as a tunable platform for realizing higher-order topological phases.
This paper theoretically demonstrates that a two-dimensional nonsymmorphic antiferromagnet can exhibit a hybrid-order topology where the bulk insulating phase displays either gapless first-order edge states or gapped edges with zero-dimensional corner states, depending solely on the specific termination geometry.
This paper introduces a novel synthetic antiferromagnetic (SAF) bias system that enables the robust stabilization of both ferromagnetic and synthetic antiferromagnetic skyrmions at zero magnetic field, achieving the direct observation of sub-20 nm SAFsks at room temperature through a combination of tailored multilayer design, field cycling, and micromagnetic modeling.
This paper demonstrates that driven-dissipative bosonic lattices, utilizing controlled pumping and uniform loss to create a Lorentzian filter of eigenmode occupations, serve as versatile platforms for directly measuring both integrated and energy-resolved Středa responses, thereby enabling the reconstruction of quantum geometric features and the characterization of topological Anderson insulators under strong disorder.
The authors developed a highly sensitive, gate-modulated reflection spectroscopy technique that successfully enables the detection of excitonic states in two-dimensional transition metal dichalcogenides from cryogenic to room temperatures, thereby offering a superior alternative to conventional reflection methods for investigating exciton physics in these materials and their heterostructures.
This paper reports the observation of an intense nonlinear force on a superconducting drum resonator within a microwave optomechanical cavity, which is consistent with the Casimir force and suggests a pathway to achieving the single-phonon nonlinear regime for enhanced quantum operations.
