This paper demonstrates that non-Markovian mechanical dissipation in optomechanical systems significantly displaces exceptional points and suppresses the Petermann factor compared to Markovian predictions, necessitating accurate bath modeling for device performance and offering a distinct spectral signature via modified cavity reflection.
Researchers have experimentally realized the parity anomaly in a genuine two-dimensional system of ultracold dysprosium atoms by engineering a synthetic dimension, observing a robust half-quantized Hall response at a topological phase transition that is protected by emergent parity symmetry.
This study reports the fabrication of high-mobility SrTiO surface electron gases via hydrogen plasma exposure that exhibit suppressed superconductivity down to 10 mK and demonstrate unique electrostatic gating behaviors, including improved modulation with larger gate separations and stochastic pinch-off events at low densities, offering a promising epitaxy-free platform for quantum devices.
The paper reveals a universal inverse-cube scaling law for projectile penetration energy in ultrathin films, attributing this enhanced resistance to finite-size suppression of long-wavelength nonaffine deformation modes that effectively increases the shear modulus regardless of material composition.
This paper establishes and numerically verifies an exact conjugation identity, , for the many-body Wilson loop in dimerized lattice models, demonstrating that the associated Berry phase satisfies even in regimes where the phase is not symmetry-quantized.
This paper predicts that supercurrents in superconductor/-wave altermagnet heterostructures can generate a Néel torque via spin-triplet correlations, enabling the dissipationless control of Néel vectors for applications in advanced memory and computing technologies.
This study utilizes SpookyNet machine-learning force fields and density-functional theory to demonstrate that aminobenzene-functionalized Janus graphene serves as a high-capacity, structurally defined anode for sodium-ion batteries, offering a low-voltage plateau, negligible volume change, and significantly faster ion diffusivity compared to conventional hard carbon.
This study investigates the coupling between surface acoustic waves and ferromagnetic resonance in a CoFeB film on a LiNbO3 substrate, revealing an unexpected 2-fold symmetry in SAW energy absorption that is attributed to weak in-plane uniaxial anisotropy rather than dipolar interactions.
This paper presents an innovative ion-beam-induced exfoliation process using Cr-implantation on (100)-oriented -GaO single crystals to fabricate microtubes that can be unrolled into high-quality, transferable nanomembranes, offering a scalable and tunable alternative to conventional mechanical exfoliation.
This study demonstrates that applying a magnetic field to narrow channels of delafossite metals PdCoO and PtCoO induces a unique directional ballistic magnetoresistance regime, where the transport properties are governed by Fermi surface anisotropy and field-modified boundary scattering rather than bulk behavior.
