Thermodynamics of doped Kondo insulator in one dimension: Finite Temperature DMRG Study
N. Shibata, H. Tsunetsugu
The finite-temperature density-matrix renormalization-group method is applied to the one-dimensional Kondo lattice model near half filling to study its thermodynamics. The spin and…
Spin, Charge and Quasiparticle Gaps in the One-Dimensional Kondo Lattice with f^2 Configuration
S. Watanabe, Y. Kuramoto, T. Nishino +1
The ground state properties of the one-dimensional Kondo lattice with an f^2 configuration at each site are studied by the density matrix renormalization group method. At half-fill…
Temperature-induced gap formation in dynamic correlation functions of the one-dimensional Kondo insulator --- Finite-temperature density-matrix renormalization-group study ---
Tetsuya Mutou, Naokazu Shibata, Kazuo Ueda
Combination of the finite-temperature density-matrix renormalization-group and the maximum entropy presents a new method to calculate dynamic quantities of one-dimensional many-bod…
SU(4) spin-orbit critical state in one dimension
Yasufumi Yamashita, Naokazu Shibata, Kazuo Ueda
Effect of quantum fluctuations concerned with the orbital degrees of freedom is discussed for the model with SU(4) symmetry in one dimension. An effective Hamiltonian is derived fr…
Metal-Insulator Transition Accompanied with a Charge Ordering in the One-dimensional t-J' Model
Tetsuya Mutou, Naokazu Shibata, Kazuo Ueda
We study the metal-insulator transition accompanied with a charge ordering in the one-dimensional (1D) t-J' model at quarter filling by the density matrix renormalization group met…
