Exact spontaneous plaquette ground states for high-spin ladder models
We study the exchange physics in high-spin Mott insulating systems with S=3/2 which is realizable in ultracold atomic systems. The high symmetry of SO 5 or SU 4 therein renders stronger quantum fluctuations than the usual spin-1 /2 systems. A spontaneous plaquette ground state without any site and bond spin orders is rigorously proved in a ladder spin-3 /2 model, whose topological excitations e...
متن کاملExact Solution of a Model of Localization
The exact solution is presented for the "susceptibility," χ (the number of sites covered by the maximally extended eigenfunction), for the zero-energy solutions of a hopping model on a randomly dilute Cayley tree. If p is the concentration, then χ~(p*−p)−1 with p*~pce1/ξ1, where pc is the critical percolation concentration and ξ1 the one-dimensional localization length. This result is argued to...
متن کاملExact solution of a stochastic SIR model
Abstract The susceptible-infectious-recovered (SIR) model describes the evolution of three species of individuals which are subject to an infection and recovery mechanism. A susceptible S can become infectious with an infection rate β by an infectious Itype provided that both are in contact. The Itype may recover with a rate γ and from then on stay immune. Due to the coupling between the differ...
متن کاملExact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement
Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve exactly a novel Yang-Baxter spin-1/2 chain model with inhomogeneous and anisotropic short-range interactions. For the ground state, we show the behavior of neighboring entanglement in the parameter space and find tha...
متن کاملExact Solution of the Gauge Symmetric p-Spin Glass Model on a Complete Graph
We consider a gauge symmetric version of the p-spin glass model on a complete graph. The gauge symmetry guarantees the absence of replica symmetry breaking and allows to fully use the interpolation scheme of Guerra [4] to rigorously compute the free energy. In the case of pairwise interactions (p = 2), where we have a gauge symmetric version of the Sherrington-Kirkpatrick model, we get the free...
