Modeling of jitter correction methods for asynchronous optical sampling
Mayuri Nakagawa, Natsuki Kanda, Ryusuke Matsunaga
Timing jitter management is crucial in asynchronous optical sampling (ASOPS) and dual-comb spectroscopy to maintain spectral bandwidth and fidelity. However, a quantitative framewo…
Magnetic Field-Tunable Repulsive Exciton-Exciton Interaction in the van der Waals Antiferromagnet NiPS
Kaiyang Huang, Jaena Park, Zhuo Yang +4
Two ultra-narrow absorption peaks around 1.5 eV, which are widely believed to originate from a transition from a spin-orbital entangled triplet to a singlet state, in the two-dimen…
Transient Reserves, Sink Dampers, and the Failure of Eigenvalue Reasoning in the Attention Propagator
Li Hengyu
The attention matrix of a causal transformer is row-stochastic, iterated over depth, and non-normal by construction. For non-normal operators, eigenvalues control only asymptotic b…
Fingerprint, Not Blueprint: How Positional Schemes Set the Default Spectral Algebra of Attention
Li Hengyu
The pre-softmax score of an attention head is a bilinear form in a learned operator . Because M is generally non-symmetric, hence non-norm…
Evolution of the intertwining correlated topological phases in iron-based superconductor Fe(Te,Se)
Yue Sun, Shiying He, Zhongyi Zhang +16
Multiple topological electronic phases can coexist within a single quantum material and induce different topological superconducting states, offering deeper insights into interplay…
