Non-uniform Quantum Spin Chains: Simulations of Static and Dynamic Properties

摘要: Since magnetic materials are often composed of magnetically isolated chains, their properties can be described by the one-dimensional quantum Heisenberg model. The transfer matrix (QTM) method based on a checkerboard structure has been applied for alternating spin chains. To increase length in Trotter direction we apply density-matrix renormalization technique and check efficiency parallelization part code: construction matrix. Next, using Matrix Product State representation, time evolution ground-state magnetization performed after sudden change field.
