Exact dynamics in the central-spin model
Using the Bethe ansatz, we present a general formula for the dynamics of the central spin in the central-spin model with inhomogeneous Heisenberg couplings and with a central magnetic field. We evaluate this formula both analytically and numerically for a fully polarized bath. For this configuration, we find, after an initial decay, an oscillatory behaviour of the central spin at all times. PAC...
متن کاملExact dynamics of XX central spin models
The dynamical behavior of a star network of spins, wherein each of N decoupled spins interact with a central spin through non uniform Heisenberg XX interaction is exactly studied. The time-dependent Schrödinger equation of the spin system model is solved starting from an arbitrary initial state. The resulting solution is analyzed and briefly discussed.
متن کاملcentral-spin model with homogeneous couplings
We calculate exactly the time-dependent reduced density matrix for the central spin in the central-spin model with homogeneous Heisenberg couplings. Therefrom, the dynamics and the entanglement entropy of the central spin are obtained. A rich variety of behaviors is found, depending on the initial state of the bath spins. For an initially unpolarized unentangled bath, the polarization of the ce...
متن کاملExact out-of-equilibrium central spin dynamics from integrability
We consider a Gaudin magnet (central spin model) with a time-dependent exchange couplings. We explicitly show that the Schrödinger equation is analytically solvable in terms of generalized hypergeometric functions for particular choices of the time dependence of the coupling constants. Our method establishes a new link between this system and the ( ) SU 2 Wess–Zumino–Witten model, and sheds new...
متن کاملEigen model as a quantum spin chain: exact dynamics.
We map the Eigen model of biological evolution [Naturwissenschaften 58, 465 (1971)] into a quantum spin model with non-Hermitian Hamiltonian. Based on such a connection, we derive exact relaxation periods for the Eigen model to approach static energy landscape from various initial conditions. We also study a simple case of dynamic fitness function.
