Field-induced quantum criticality and universal temperature dependence of the magnetization of a spin-1/2 heisenberg chain.
High-precision dc magnetization measurements have been made on Cu(C4H4N2) (NO3)2 in magnetic fields up to 14.7 T, slightly above the saturation field Hs=13.97 T, in the temperature range from 0.08 to 15 K. The magnetization curve and differential susceptibility at the lowest temperature show excellent agreement with exact theoretical results for the spin-1/2 Heisenberg antiferromagnet in one d...
متن کاملThe spin-1/2 Heisenberg chain: thermodynamics, quantum criticality and spin-Peierls exponents
We present numerical and analytical results for the thermodynamical properties of the spin-1/2 Heisenberg chain at arbitrary external magnetic field. Special emphasis is placed on logarithmic corrections in the susceptibility and specific heat at very low temperatures (T/J = 10) and small fields. A longstanding controversy about the specific heat is resolved. At zero temperature the spin-Peierl...
متن کاملLow-temperature properties of the spin-1 antiferromagnetic Heisenberg chain with bond-alternation
We investigate the low-temperature properties of the spin-1 antiferromagnetic Heisenberg chain with bond-alternation by the quantum Monte Carlo method (loop algorithm). The strength of bond-alternation at the gapless point is estimated as δc = 0.2595 ± 0.0005. We confirm numerically that the low-temperature properties at the gapless point are consistent with field theoretical predictions. The n...
متن کاملThermodynamics of the Anisotropic Spin - 1 / 2 Heisenberg Chain and Related Quantum Chains ∗
The free energy and correlation lengths of the spin-1/2 XY Z chain are studied at finite temperature. We use the quantum transfer matrix approach and derive non-linear integral equations for all eigenvalues. Analytic results are presented for the low-temperature asymptotics, in particular for the critical XXZ chain in an external magnetic field. These results are compared to predictions by conf...
متن کاملMultiple frustration-induced plateaus in a magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain
Abstract. Magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain is examined by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method. Multiple frustrationinduced plateaus in a magnetization process of this geometrically frustrated system are found provided that a relative ratio betwe...
