Modeling Hawkish-Dovish Latent Beliefs in Multi-Agent Debate-Based LLMs for Monetary Policy Decision Classification
Kaito Takano, Masanori Hirano, Kei Nakagawa
Accurately forecasting central bank policy decisions, particularly those of the Federal Open Market Committee(FOMC) has become increasingly important amid heightened economic uncer…
Search for planetary-mass ultra-compact binaries using data from the first part of the LIGO--Virgo--KAGRA fourth observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
We present a search for gravitational waves from inspiraling, planetary-mass ultra-compact binaries using data from the first part of the fourth observing run of LIGO, Virgo and KA…
Stability of current-carrying states in hard-core bosons with long-range hopping on a square lattice
Yoshihiro Yabuuchi, Ippei Danshita
We investigate the stability of current-carrying states with quasi-momentum in the Bose-condensed phase of the hard-core Bose-Hubbard model on a square lattice, where particles…
Pseudo-Nambu-Goldstone Dark Matter in Flux Compactification
Kento Akamatsu, Takuya Hirose, Nobuhito Maru +1
We study a six-dimensional U(1) gauge theory compactified on a magnetized torus, where the zero mode of the extra-dimensional gauge field (a Wilson-line (WL) scalar field) play…
Joint neutrino oscillation analysis from the T2K and NOvA experiments
NOvA, T2K Collaborations, : +597
The landmark discovery that neutrinos have mass and can change type (or "flavor") as they propagate -- a process called neutrino oscillation -- has opened up a rich array of theore…
Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe. This motivates directi…
Regression of Suspension Violin Modes in KAGRA O3GK Data with Kalman Filters
Lucas Moisset, Marco Meyer-Conde, Christopher Allene +4
Suspension thermal modes in interferometric gravitational-wave detectors produce narrow, high-Q spectral lines that can contaminate gravitational searches and bias parameter estima…
Kondo breakdown induced by non-Hermitian complex hybridization
Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami
Recently, a non-Hermitian Anderson impurity model with one-body loss has been studied in [Phys. Rev. B 111, 125157 (2025)}], and it has been demonstrated that the renormalization e…
The moduli spaces of left-invariant statistical structures on Lie groups
Hikozo Kobayashi, Yu Ohno, Takayuki Okuda +1
In the context of information geometry, the concept known as left-invariant statistical structure on Lie groups is defined by Furuhata--Inoguchi--Kobayashi (Inf Geom 4(1):177--188,…
Shadow of rotating black holes with consistent thermodynamics
Che-Yu Chen, Chiang-Mei Chen, Nobuyoshi Ohta
Quantum effects in general induce scale dependence in the coupling constants. We explore this possibility in gravity, with a scale-dependent Newton coupling. When applied to Kerr b…
Detection of ferroic octupole ordering in -wave altermagnetic rutile-type compounds
Masaichiro Mizumaki, Norimasa Sasabe, Takayuki Uozumi +2
