Multiplicity, probabilities, and canonical sectors for the cold QCD matter
Kouji Kashiwa, Hiroaki Kouno
At sufficiently low temperature, without requiring any numerical data at finite real chemical potential, we can clarify the canonical partition function with fixed quark number via…
Gauge invariant input to neural network for path optimization method
Yusuke Namekawa, Kouji Kashiwa, Akira Ohnishi +1
We investigate the efficiency of a gauge invariant input to a neural network for the path optimization method. While the path optimization with a completely gauge-fixed link-variab…
Superconductivity in Al-Nb-Ti-V-Zr multicomponent alloy
Yuta Harayama, Jiro Kitagawa
The superconducting high-entropy alloys (HEAs) recently attract considerable attention due to their exciting properties, such as the robustness of superconductivity against atomic…
Stiff equation of state for a holographic nuclear matter as instanton gas
Kazuo Ghoroku, Kouji Kashiwa, Yoshimasa Nakano +2
In a holographic model, which was used to investigate the color superconducting phase of QCD, a dilute gas of instantons is introduced to study the nuclear matter. The free energy…
Nonanalyticity, sign problem and Polyakov line in Z3-symmetric heavy quark model at low temperature: Phenomenological model analyses
Hiroaki Kouno, Kouji Kashiwa, Takehiro Hirakida
The nonanalyticity and the sign problem in the Z3-symmetric heavy quark model at low temperature are studied phenomenologically. For the free heavy quarks, the nonanalyticity is an…
Persistent homology analysis for dense QCD effective model with heavy quarks
Kouji Kashiwa, Takehiro Hirakida, Hiroaki Kouno
The isospin chemical potential region is known as the sign-problem free region of quantum chromodynamics (QCD). In this paper, we introduce the isospin chemical potential to the th…
Anatomy of the dense QCD matter from canonical sectors
Kouji Kashiwa, Hiroaki Kouno
We investigate the nuclear and the quark matter at finite real chemical potential () and low temperature from the viewpoint of the canonical sectors constructed via t…
Flat-band solutions in -dimensional decorated diamond and pyrochlore lattices: Reduction to molecular problem
Tomonari Mizoguchi, Hosho Katsura, Isao Maruyama +1
Flat-band models have been of particular interest from both fundamental aspects and realization in materials. Beyond the canonical examples such as Lieb lattices and line graphs, a…
Representation of non-special curves of genus 5 as plane sextic curves and its application to finding curves with many rational points
Momonari Kudo, Shushi Harashita
In algebraic geometry, it is important to provide effective parametrizations for families of curves, both in theory and in practice. In this paper, we present such an effective par…
