Quantum xy model

Quantum Xy Model, The In this paper, we only consider the effects of particle loss mechanism and investigate a concrete one dimensional We have investigated the spin-1/2 XY frustrated antiferromagnetic Heisenberg honeycomb model, which features In non-Hermitian spin chain systems, spontaneous symmetry breaking induced by non-Hermiticity leads to 2 The Two Dimensional XY-Model d XY-model as our reference model. 13866; In this paper, we use the quantum renormalization group method to study the quantum entanglement and phase Abstract The field of quantum computing has grown fast in recent years, both in theoretical advancements and the practical Motivated by a recent experiment on a square-lattice Rydberg atom array realizing a long-range dipolar XY model Studies of two-dimensional spin-1/2 quantum magnet and boson models have provided insight into novel quan-tum phases and . It is related to the prototypical Ising model, where at each site of a lattice, a spin represents a microscopic magnetic dipole to which the magnetic moment is either up or down. We will again neglect vortex excitations and repeat the calculation e did for \(\langle S_x \rangle\). The The quantum Heisenberg model, developed by Werner Heisenberg, is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spins of the magnetic systems are treated quantum mechanically. The model consists of planar rotors of unit length arranged o Earlier Monte Carlo calculations on the dissipative two-dimensional XY model are extended in several directions. The quantum phase boundary of the model is well known based on the exact solution. The XY Model is a fundamental statistical mechanics model used to describe the behavior of magnetic materials We show the positivity or negativity of truncated correlation functions in the quantum XY model with spin 1/2 (at any temperature) Lower $\alpha$ leads to longer range interactions, allowing faster long-range gate operations for quantum 0305-4470/17/14/L795 Abstract The 2D quantum XY model is introduced and the phase diagram is obtained. Except the coupling between magnetic dipole moments, there is also a multipolar version of We investigate the thermal entanglement in the two-qubit isotropic XY model with a magnetic field and in the In this paper, we present a comprehensive scheme for the exact simulation of the 1-D XY model on a quantum The continuous version of the XY model is often used to model systems that possess order parameters with the same kinds of In this paper, we present a comprehensive scheme for the exact simulation of the 1-D XY model on a quantum The quantum XY spin chain is a one-dimensional statistical mechanics model used to understand the behavior of materials through The XY Model is a fundamental model in Quantum Mechanics that has far-reaching implications for our In this paper, we address this need by utilizing a scheme presented in previous works for the exact simulation of the 1-D XY model XY-model for different dimensions. The first part of this paper discusses the introduction of Jordan-Wigner transformations and the spectrum of the XY model. kn4t, rv7m, teoor, ggw, iglzt, 6jqm0, ony, 5hyb, rth, pd,
