We study the system of hard-core bosons (HCB) with two species in the three-dimensional lattice at finite temperatures. In the strong-correlation limit, the system becomes the bosonic t-J model, that is, the t-J model of "bosonic electrons". The b...

In the present paper, we study a system of doped antiferromagnet in three
dimensions at finite temperatures by using the t-J model, a canonical model of
strongly-correlated electrons. We employ the slave-fermion representation of
electrons in whic...

Education of creativity is highly important in engineering education. Since 2006, we have been working on a project to encourage the students of Nara National College of Technology (NNCT) to develop their creativity. For this purpose, a science cl...

We study the three-dimensional U(1) lattice gauge theory of a CPTex spinon
(Schwinger boson) field and a Higgs field. It is a bosonic Tex-Tex model in
slave-particle representation, describing the antiferromagnetic (AF) Heisenberg
spin model with...

We formulate and study a quantum field theory of a microtubule, a basic
element of living cells. Following the quantum theory of consciousness by
Hameroff and Penrose, we let the system to reduce to one of the classical
states without measurement ...

We introduce a U(1) lattice gauge theory with dual gauge fields and study its
phase structure. This system is motivated by unconventional superconductors
like extended s-wave and d-wave superconductors in the strongly-correlated
electron systems. ...

We study the phase structure of the 3D nonlocal compact U(1) lattice gauge
theory coupled with a Higgs field by means of Monte-Carlo simulations. The
nonlocal interactions among gauge variables are along the temporal direction
and mimic the effect...

In this paper, we study a 3D compact U(1) lattice gauge theory with a variety
of nonlocal interactions that simulates the effects of gapless/gapful matter
fields. This theory is quite important to investigate the phase structures of
QEDTex and st...

A gauge model of neural network is introduced, which resembles the Z(2) Higgs
lattice gauge theory of high-energy physics. It contains a neuron variable Tex on each site Tex of a 3D lattice and a synaptic-connection variable

We introduce a 3D compact U(1) lattice gauge theory having nonlocal
interactions in the temporal direction, and study its phase structure. The
model is relevant for the compact QEDTex and strongly correlated electron
systems like the t-J model of...

We study the (de)localization phenomena of one-component lattice fermions in
spin backgrounds. The O(3) classical spin variables on sites fluctuate
thermally through the ordinary nearest-neighbor coupling. Their complex
two-component (CPTex-Schwi...

We study the statistics of holons and spinons in the framework of the gauge
theory. We start with the t-J model in the slave-boson formalism and use
Chern-Simons gauge theory to study the statistics transmutation of
quasiexcitations in the charge-...
