Connecting distant ends of one-dimensional critical systems by a sine-square deformation
Toshiya Hikihara, Tomotoshi Nishino
We study the one-dimensional quantum critical spin systems with the sine-square deformation, in which the energy scale in the Hamiltonian at the position is modified by the fun…

Field and temperature dependence of the NMR relaxation rate in the magnetic quadrupolar liquid phase of spin-1/2 frustrated ferromagnetic chains
Masahiro Sato, Toshiya Hikihara, Tsutomu Momoi
It is generally difficult to experimentally distinguish magnetic multipolar orders in spin systems. Recently, it was proposed that the temperature dependence of the nuclear magneti…

Magnetic phase diagram of the spin-1/2 antiferromagnetic zigzag ladder
T. Hikihara, T. Momoi, A. Furusaki +1
We study the one-dimensional spin-1/2 Heisenberg model with antiferromagnetic nearest-neighbor J_1 and next-nearest-neighbor J_2 exchange couplings in magnetic field h. With varyin…
