Open AccessInside stent placement is suitable for preoperative biliary drainage in patients with perihilar cholangiocarcinoma
Endoscopic biliary stenting (EBS) is commonly used for preoperative drainage of localized perihilar cholangiocarcinoma (LPHC). This study retrospectively compared the utility of inside stent (IS) and conventio...

Open AccessInvestigation of Complex ϕ4 Theory at Finite Density in Two Dimensions Using TRG
We study the two-dimensional complex ϕ4 theory at finite chemical potential using the tensor renormalization group. This model exhibits the Silver Blaze phenomenon in which bulk observables are independent of the...

Open AccessTensor network analysis of critical coupling in two dimensional ϕ4 theory
We make a detailed analysis of the spontaneous Z2-symmetry breaking in the two dimensional real ϕ4 theory with the tensor renormalization group approach, which allows us to take the thermodynamic limit easily and...

Open AccessTensor network formulation for two-dimensional lattice \( \mathcal{N} \) = 1 Wess-Zumino model
Supersymmetric models with spontaneous supersymmetry breaking suffer from the notorious sign problem in stochastic approaches. By contrast, the tensor network approaches do not have such a problem since they a...

Eigenspectrum Calculation of the O(a)-Improved Wilson-Dirac Operator in Lattice QCD Using the Sakurai-Sugiura Method
We have developed a computer code to find eigenvalues and eigenvectors of non-Hermitian sparse matrices arising in lattice quantum chromodynamics (lattice QCD). The Sakurai-Sugiura (SS) method (Sakurai and Sug...
