Stiffening of fluid membranes due to thermal undulations: density matrix renormalization group study
Yoshihiro Nishiyama
It has been considered that the effective bending rigidity of fluid membranes should be reduced by thermal undulations. However, recent thorough investigation by Pinnow and Helfric…
Asymptotic Behavior of the Emptiness Formation Probability in the Critical Phase of XXZ Spin Chain
V. E. Korepin, S. Lukyanov, Y. Nishiyama +1
We study the Emptiness Formation Probability (EFP) for the spin 1/2 XXZ spin chain. EFP P(n) detects a formation of ferromagnetic string of the length n in the ground state. It is…
Quantum-fluctuation-induced collisions and subsequent excitation gap of an elastic string between walls
Yoshihiro Nishiyama
An elastic string embedded between rigid walls is simulated by means of the density-matrix renormalization group. The string collides against the walls owing to the quantum-mechani…
Quantum Correlations and Number Theory
H. E. Boos, V. E. Korepin, Y. Nishiyama +1
We study spin-1/2 Heisenberg XXX antiferromagnet. The spectrum of the Hamiltonian was found by Hans Bethe in 1931. We study the probability of formation of ferromagnetic string in…
