Density of states of disordered Dirac particles: Infinitely many operators with negative scaling dimensions and freezing transitions
Shinsei Ryu, Christopher Mudry, Akira Furusaki
The global density of states (GDOS) close to the band center for a particle hopping on a square lattice and subjected to disorder that preserves the bipartite symmetry of the…
Correlation Amplitudes for the spin-1/2 XXZ chain in a magnetic field
T. Hikihara, A. Furusaki
We present accurate numerical estimates for the correlation amplitudes of leading and main subleading terms of the two- and four-spin correlation functions in the one-dimensional s…
Boundary contributions to specific heat and susceptibility in the spin-1/2 XXZ chain
A. Furusaki, T. Hikihara
Exact low-temperature asymptotic behavior of boundary contribution to specific heat and susceptibility in the one-dimensional spin-1/2 XXZ model with exchange anisotropy 1/2 < Δ\le…
Ground-state phase diagram of the one-dimensional half-filled extended Hubbard model
M. Tsuchiizu, A. Furusaki
We revisit the ground-state phase diagram of the one-dimensional half-filled extended Hubbard model with on-site (U) and nearest-neighbor (V) repulsive interactions. In the first h…
Dynamical Structure Factor in Cu Benzoate and other spin-1/2 antiferromagnetic chains
F. H. L. Essler, A. Furusaki, T. Hikihara
Recent experiments of the quasi-one-dimensional spin-1/2 antiferromagnet Copper Benzoate established the existence of a magnetic field induced gap. The observed neutron scattering…
