Field-Induced Quantum Spin Nematic Liquid Phase in the S=1 Antiferromagnetic Heisenberg Chain with Additional Interactions

چکیده
Abstract The magnetization process of the S = 1 antiferromagnetic chain with single-ion anisotropy D and biquadratic interaction is investigated using numerical diagonalization. Both interactions stabilize 2-magnon Tomonaga-Luttinger liquid (TLL) phase in process. Based on several excitation gaps calculated by diagonalization, some diagrams are presented. These reveal that spin nematic dominant TLL appears at higher magnetizations for sufficiently large negative .

Dynamics of the antiferromagnetic Heisenberg spin − 1 / 2 chain
In magnetic systems, interactions between electrons can be described by an effective spinspin interaction. When the wavefunctions of the electrons overlap mainly in one direction, the system behaves as an effectively one-dimensional spin chain. A special class of such a spin chain is the anisotropic Heisenberg model, also called the XXZ model. Exact wavefunctions for the (gapped) antiferromagne...
متن کاملSusceptibility of the spin 1/2 Heisenberg antiferromagnetic chain.
Highly accurate results are presented for the susceptibility, χ(T ) of the s = 1/2 Heisenberg antiferromagnetic chain for all temperatures, using the Bethe ansatz and field theory methods. After going through a rounded peak, χ(T ) approaches its asympotic zero-temperature value with infinite slope. 75.10.Jm Typeset using REVTEX 1 In a pioneering work in 1964, Bonner and Fisher estimated numeric...
متن کاملFractional spinon excitations in the quantum Heisenberg antiferromagnetic chain
One of the simplest quantum many-body systems is the spin-1/2 Heisenberg antiferromagnetic chain, a linear array of interacting magnetic moments. Its exact ground state is a macroscopic singlet entangling all spins in the chain. Its elementary excitations, called spinons, are fractional spin-1/2 quasiparticles created and detected in pairs by neutron scattering. Theoretical predictions show tha...
متن کاملFirst Order Transition in the Frustrated Antiferromagnetic Heisenberg S=1 Quantum Spin Chain.
We study a frustrated Heisenberg S 1 quantum spin chain with next-nearest neighbor (NNN) coupling a using a variational ansatz and the density matrix renormalization group. We find as quantum remnants of the phase transition in the classical chain a disorder point at a D 0.284͑1͒ and a Lifshitz point at a L 0.3725͑25͒. Our main finding is a first-order transition from an Affleck-Kennedy-Lieb-...
متن کاملMagnetic-field-induced changes of the isotropic-nematic phase transition in side-chain polymer liquid crystals.
The isotropic-nematic (I-N) phase transition of side-chain polymer liquid crystals is intrinsically a weak first-order transition with a biphasic region spread over a wide temperature interval. In the presence of high magnetic fields we find the I-N transition to become a strong first order. The I-N biphasic region shrinks its temperature window as larger magnetic fields are applied, until it c...
