The -mode frequencies in cold neutron stars and nuclear saturation parameters
Hajime Sotani, Hajime Togashi
Oscillation frequencies excited in neutron stars are crucial for extracting their interior properties. In addition to the fundamental and pressure modes, the gravity (-) modes c…
Universality of dual mass-scaled fundamental modes in two-fluid neutron stars with mirror dark matter
Hajime Sotani, Ankit Kumar
Universal relations provide a particularly useful way to extract physical information from neutron star observables in the presence of various uncertainties by reducing the depende…
Non-radial pulsations of gravitationally coupled two-fluid neutron stars in general relativity
Ankit Kumar, Daniel A. Caballero, Hajime Sotani +1
Non-radial oscillations of neutron stars provide a powerful probe of stellar structure and relativistic gravity, but a fully general relativistic treatment for gravitationally coup…
Dual terahertz frequency combs for photonic RF readout of refractive index sensing with frequency multiplication and active-dummy temperature compensation
Masayuki Higaki, Yoshiaki Nakajima, Shuji Taue +4
We present a unified refractive index (RI) sensing platform that integrates THz-comb-based frequency multiplication with dual-comb active-dummy temperature compensation. In convent…
Evaluating adaptive and generative AI-based feedback and recommendations in a knowledge-graph-integrated programming learning system
Lalita Na Nongkhai, Jingyun Wang, Adam Wynn +1
This paper introduces the design and development of a framework that integrates a large language model (LLM) with a retrieval-augmented generation (RAG) approach leveraging both a…
Violation of local equilibrium thermodynamics in one-dimensional Hamiltonian-Potts model
Hitomi Endo, Michikazu Kobayashi
We investigate nonequilibrium phase coexistence associated with a first-order phase transition by numerically studying a one-dimensional Hamiltonian-Potts model with fractional spa…
