Quantum Phase Transition in the One-Dimensional XZ Model
We introduce a one-dimensional (1D) XZ model with alternating σ i σ z i+1 and σ x i σ x i+1 interactions on even/odd bonds, interpolating between the Ising model and the quantum compass model. We present two ways of its exact solution by: (i) mapping to the quantum Ising models, and (ii) using fermions with spin 1/2. In certain cases the nearest neighbor pseudospin correlations change discontin...
متن کاملAnalytical approach to the quantum-phase transition in the one-dimensional spinless Holstein model
We study the one-dimensional Holstein model of spinless fermions interacting with dispersionless phonons by using a recently developed projector-based renormalization method (PRM). At half-filling the system shows a metal-insulator transition to a Peierls distorted state at a critical electron-phonon coupling where both phases are described within the same theoretical framework. The transition ...
متن کاملQuantum Phase Transition and Finite-Size Scaling of the One-Dimensional Ising Model
We study the quantum phase transition in the one-dimensional Ising model at zero temperature. As the strength g of the transverse field is changed, the system undergoes a quantum phase transition from an ordered to a disordered phase, characterized by spontaneous magnetization in the z-direction. We apply the standard technique of finite-size scaling in statistical mechanics to detect the natur...
متن کاملQuantum phase transition in one dimensional extended Kondo lattice model away from half filling
We study one dimensional extended Kondo lattice model, described by the t − J Hamiltonian for conduction electrons away from half filling and the Heisenberg Hamiltonian for localized spins at half filling. Following Shankar,[1] we find an effective field theory for this model, where doped holes are represented by massless Dirac fermions (holons) and spin excitations are fractionalized into rela...
متن کاملQuantum Phase Transitions in an Integrable One-Dimensional Spin Model
A one-dimensional spin model, recently introduced and solved exactly, is studied. The solution, showing the appearance of a first-order quantum phase transition, is explicitly carried out and verified. Moreover, new results are found by generalizing the model to include anisotropy, thereby giving additional phases with both first-order and continuous quantum phase transitions. These transitions...
