Abstract We analyze the chiral phase transition of the Nambu-Jona-Lasinio model in the cold and dense region on the lattice, developing the Grassmann version of the anisotropic tensor renormalization group algorithm. The model is formulated with the

Abstract Tensor network is an attractive approach to the field theory with negative sign problem. The complex ϕ 4 theory at finite density is a test bed for numerical algorithms to verify their effectiveness. The model shows a characteristic feature

In this paper, we propose a parallel computing method for the Higher Order Tensor Renormalization Group (HOTRG) applied to a $d$-dimensional $( d \geq 2 )$ simple lattice model. Sequential computation of the HOTRG requires $O ( \chi^{4 d - 1} )$ comp

We have developed a spin-resolved resonant electron energy-loss spectroscopy (SR-rEELS) in the primary energy of 0.3--1.5 keV, which corresponds to the core excitations of $2p$-$3d$ absorption of transition metals and $3d$-$4f$ absorption of rare-ear

We investigate the phase transition of the four-dimensional Ising model with two types of tensor network scheme, one is the higher-order tensor renormalization group and the other is the anisotropic tensor renormalization group. The results for the i

Purpose Because the true prevalence of food allergy (FA), as based on the results of an oral food challenge test (OFC), is unknown, it is likely that children with suspected FA unnecessarily eliminate potentially causative foods. This study aimed to

We apply the higher-order tensor renormalization group (HOTRG) to the four-dimensional ferromagnetic Ising model, which has been attracting interests in the context of the triviality of the scalar $\phi^4_{d=4}$ theory. We investigate the phase trans

To discuss the effective interactions between macroanions, such as acidic proteins, the radial distribution function between macroanions, gMM(r), was calculated using an integral equation theory with a charged hard spheres model under weak coupling c
