Statistics of Min-max Normalized Eigenvalues in Random Matrices
Hyakka Nakada, Shu Tanaka
Random matrix theory has played an important role in various areas of pure mathematics, mathematical physics, and machine learning. From a practical perspective of data science, in…
Fermionic domain-wall Skyrmions of QCD in a magnetic field
Patrick Copinger, Minoru Eto, Muneto Nitta +1
The ground state of low-energy QCD matter in strong magnetic fields is either a chiral soliton lattice (CSL), a periodic array of neutral pion domain walls (chiral solitons) perpen…
Creation of domain-wall skyrmions in chiral magnets with Landau-Lifshitz-Gilbert dynamics and demagnetization
Sven Bjarke Gudnason, Yuki Amari, Muneto Nitta
Absorption of an isolated bulk magnetic skyrmion into an empty domain wall in a chiral ferromagnetic system is studied using the Landau-Lifshitz-Gilbert equation with and without t…
Spinning extremal dyonic black holes in Einstein-Maxwell-dilaton theory
Jose Luis Blázquez-Salcedo, Carlos Herdeiro, Eugen Radu +2
We propose a general framework for the study of asymptotically flat spinning dyonic {\it extremal} black holes (eBHs) in Einstein-Maxwell-dilaton theory. Restricting to the s…
Measurement of the solar neutrino interaction rate below 3.49 MeV in Super-Kamiokande-IV
Kamiokande Collaboration, A. Yankelevich, K. Abe +250
Super-Kamiokande (SK) has observed solar neutrino elastic scattering at recoil electron kinetic energies () as low as 3.49 MeV to study neutrino flav…
Tensor Renormalization Group Calculations of Partition-Function Ratios
Satoshi Morita, Naoki Kawashima
The behavior of dimensionless quantities defined as ratios of partition functions is analyzed to investigate phase transitions and critical phenomena. At criticality, the universal…
Real-World Robot Control by Deep Active Inference With a Temporally Hierarchical World Model
Kentaro Fujii, Shingo Murata
Robots in uncertain real-world environments must perform both goal-directed and exploratory actions. However, most deep learning-based control methods neglect exploration and strug…
Sliding of cylindrical shell into a rigid hole
Yukiho Matsumoto, Keisuke Yoshida, Tomohiko G. Sano
Fitting two different materials is a versatile methodology in manufacturing complex structures. One of the canonical models for fitting is the snap-fit model, in which flexible mat…
The LMT 2 millimeter receiver system (B4R). II. Science demonstration observations toward Orion-KL/OMC-1
Teppei Yonetsu, Ryohei Kawabe, Yuki Yoshimura +26
We present the results of mapping and single-point spectral scans toward Orion-KL/OMC-1 performed as science demonstrations of a 2 mm SIS receiver, the Band 4 Receiver (B4R), insta…
The LMT 2 Millimeter Receiver System (B4R). I. Overview and Results of Science Demonstration
Ryohei Kawabe, Takeshi Sakai, Kunihiko Tanaka +30
We report on the results of the on-sky test and science demonstration conducted with the 2 mm receiver system, B4R, on the 50 m Large Millimeter Telescope (LMT), located at an alti…
Maximizing the nondemolition nature of a quantum measurement via an adaptive readout protocol
Arjen Vaartjes, Rocky Yue Su, Laura A. O'Neill +15
Quantum error correction (QEC) requires non-invasive measurements for fault tolerant quantum computing. Deviations from ideal quantum non-demolition (QND) measurements can disturb…
Systematic dispersion engineering of crystalline microresonators for broadband and coherent frequency comb generation
Liu Yang, Ryomei Takabayashi, Hiroki Moriguchi +9
Ultraprecision machining offers a powerful route to dispersion control in crystalline microresonators, allowing the design of waveguide geometries for tailoring the spectrum of mic…

We discuss the exact quantization of general one-dimensional potentials in view of the exact-WKB formalism. Building on our previous work, we perform analytic continuations across…
Verifying the failing supernova constraint on dark photons with two-dimensional hydrodynamic simulations
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri
Recent studies on the dark photon (DP) production in collapsing stars argue that the cooling effect induced by DPs can hinder supernova explosions and lead to a ``failing supernova…
Dense packing of the surface code: code deformation procedures and hook-error-avoiding gate scheduling
Kohei Fujiu, Shota Nagayama, Shin Nishio +2
The surface code is one of the leading quantum error correction codes for realizing large-scale fault-tolerant quantum computing (FTQC). One major challenge in realizing surface-co…
