Level repulsion in integrable and almost-integrable quantum spin models.
The repartition of the separation between energy levels of various isotropic S=1/2 antiferromagnetic chains is studied numerically with the aim of investigating the transition from integrable to non-integrable systems. We begin by displaying the level separation distribution of the integrable Bethe chain. Then two non-integrable systems, two coupled chains and a next-nearest-neighbor coupled ch...
متن کاملDiscrete Hirota’s equation in quantum integrable models
The recent progress in revealing classical integrable structures in quantummodels solved by Bethe ansatz is reviewed. Fusion relations for eigenvalues of quantum transfer matrices can be written in the form of classical Hirota’s bilinear difference equation. This equation is also known as the completely discretized version of the 2D Toda lattice. We explain how one obtains the specific quantum ...
متن کاملΚ-deformed Covariant Phase Space and Quantum-gravity Uncertainty Relations
We describe the deformed covariant phase space corresponding to the so-called κ-deformation of D = 4 relativistic symmetries, with quantum “time” coordinate and Heisenberg algebra obtained according to the Heisenberg double construction. The associated modified uncertainty relations are analyzed, and in particular it is shown that these relations are consistent with independent estimates of qua...
متن کاملYangian, Truncated Yangian and Quantum Integrable Models
Based on the RTT relation for the given rational R-matrix the Yangian and truncated Yangian are discussed. The former can be used to generate the longrange interaction models, whereas the latter can be related to the GoryachevChaplygin(GC) gyrostat. The trigonometric extension of the Goryachev-Chaplygin gyrostat has also been shown.
متن کاملIntegrable Systems Related to Deformed so ( 5 )
We investigate a family of integrable Hamiltonian systems on Lie–Poisson spaces L+(5) dual to Lie algebras soλ,α(5) being two-parameter deformations of so(5). We integrate corresponding Hamiltonian equations on L+(5) and T ∗R5 by quadratures as well as discuss their possible physical interpretation.
