Phase structure of $Z_2$ gauge theories for frustrated antiferromagnets in two dimensions (2009)
Nakane, K., Shimizu, A., Ichinose, I.
In this paper, we study phase structure of $Z_2$ lattice gauge theories that appear as an effective field theory describing low-energy properties of frustrated antiferromagnets in two dimensions....

We study the three-dimensional (3D) compact U(1) lattice gauge theory coupled with $N$-flavor Higgs fields by means of the Monte Carlo simulations. This model is relevant to multi-component...

Angewandte Chemie International Edition, 44(2005) S.7048-53
S=1/2 quantum spin chains and ladders with random exchange coupling are studied by using an effective low-energy field theory and transfer matrix methods. Effects of the nonlocal correlations of...
Effects of Long-Range Correlations in Random-Mass Dirac Fermions (2002)
In the previous paper, we studied the random-mass Dirac fermion in one dimension by using the transfer-matrix methods. We furthermore employed the imaginary vector potential methods for calculating...
In this and subsequent papers, one dimensional system of Dirac fermions with a random-varying mass is studied by the transfer-matrix methods which we developed recently. We investigate the effects of...
In the previous paper, we studied the random-mass Dirac fermion in one dimension by using the transfer-matrix methods and by introducing an imaginary vector potential in order to calculate the...
Ichinose, I., Matsui, T., Onoda, M.
We study the slave-boson t-J model of cuprates with high superconducting transition temperatures, and derive its low-energy effective field theory for the charge-spin separated state in a...
In a recent Letter, Nayak argued that slave partices are always confined in gauge theories of strongly-correlated electron systems like the t-J model. The argument mostly relies on Elitzur's theorem...
We investigate chiral properties of the overlap lattice fermion by using solvable model in two dimensions, the gauged Gross-Neveu model. In this model, the chiral symmetry is spontaneously broken in...
Resistivity in the spin-gap state of the t-J model (1997)
Onoda, M., Ichinose, I., Matsui, T.
Being motivated by recent experimental data on YBaCuO, we calculate dc resistivity in the spin-gap state of charge- spin-separated t-J model by using a massive gauge theory of holons and spinons.The...
Quasi-excitations and superconductivity in the t-J model on a ladder (1997)
We study the t-J model on a ladder by using slave-fermion-CP^1 formalism which is quite useful for study of lightly-doped high-T_c cuprates. By integrating half of spin variables, we obtain a...
Fluctuation effects of gauge fields in the slave-boson t-J model (1997)
Ichinose, I., Matsui, T., Sakakibara, K.
We present a quantitative study of the charge-spin separation(CSS) phenomenon in a U(1) gauge theory of the t-J model of high-Tc superconductures. We calculate the critical temperature of...
Topological solitons in Chern-Simons theories for double-layer fractional quantum Hall effect (1996)
Topological excitations in Chern-Simons gauge theories which describe double-layer fractional quantum Hall effct are studied. There are two types of solitons; one is vortex and the other is...
Mechanism of the particle-flux separation in the Chern-Simons gauge theory coupled with nonrelativistic fermions is studied in a nonperturbative method. This problem is very important for the...
Finite temperature properties of the gauge theory of nonrelativistic fermions (1996)
Onoda, M., Ichinose, I., Matsui, T.
We study the finite temperature properties of the gauge theory of nonrelativistic fermions by using RPA and ladder approximation. This gauge theory is relevant to two interesting systems: high-Tc...
Statistics of holons and spinons in the t-J model (1996)
Ichinose, I., Matsui, T., Sakakibara, K.
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...

We demonstrated that MIF-1, identified initially as a binding activity that associated with the intron I element of the c-myc gene, consists of two polypeptides, the myc intron-binding peptide...
