“…Quantum spin models in one dimension traditionally attract a great deal of attention, because they often exhibit unique magnetic properties closely connected to exotic quantum ground states [1][2][3][4][5]. Although all real-world magnetic materials are essentially three dimensional a lot of them can be effectively described by the notion of onedimensional (1D) quantum Heisenberg spin models due to negligible interactions in other two spatial dimensions [5,6].…”

“…The Heisenberg chains with half-odd-integer spins have a gapless excitation spectrum and algebraic decay of correlations, while the Heisenberg chains with integer spins have an energy gap and exponential decay of correlations [1,7]. If the geometric spin frustration comes into play, however, the essential features of quantum Heisenberg chains may become more complex and possibilities for a low-energy spectrum are also broadened [2][3][4][5].…”

“…Existem muitas técnicas analíticas ou numéricas [4] para a obtenção de soluções exatas ou aproximadas para modelos de spins. Dentre essas técnicas temos o Método das Relações de Recorrência (MRR) [5,6,7], queé bastanteútil na obtenção da dinâmica de sistemas de muitos corpos quânticos.…”

“…The open quantum dynamics [1] of spin systems finds wide application in various fields of physics, e.g., quantum theory of magnetism [2], quantum information processing [3], quantum biology [4] and quantum dots [5][6][7]. Several models were proposed to study decoherence of single and multi-spin systems interacting with a surrounding environment [8].…”
