چکیده
Abstract The quantum symmetric simple exclusion process (Q-SSEP) is a model for stochastic dynamics of fermions hopping along the edges graph with Brownian noisy amplitudes and driven out-of-equilibrium by injection-extraction processes at few vertices. We present solution invariant probability measure one dimensional Q-SSEP in infinite size limit constructing steady correlation functions system density matrix expectation values. These code rich structure fluctuating correlations coherences. Although our construction does not rely on standard techniques from theory integrable systems, it based remarkable interplay between permutation groups polynomials. incidentally point out possible combinatorial interpretation via surprising connexion geometric combinatorics associahedron polytopes.

Exact Solution of the Simple Exclusion Process from Boundary Symmetry∗
The exact solution of a model of nonequilibrium physics derived from the boundary symmetry in the form of deformed Onzager algebra is presented. The symmetry is generated by nonlocal charges that render the model to be exactly solvable in the steady state and provide a unified description of the dynamics of the boundary driven process.

متن کاملDistributional Limits for the Symmetric Exclusion Process
Strong negative dependence properties have recently been proved for the symmetric exclusion process. In this paper, we apply these results to prove convergence to the Poisson and Gaussian distributions for various functionals of the process.
متن کاملPerturbations of the Symmetric Exclusion Process
One of the fundamental issues concerning particle systems is classifying the invariant measures I and giving properties of those measures for different processes. For the exclusion process with symmetric kernel p(x, y) = p(y, x), I has been completely studied. This paper gives results concerning I for exclusion processes where p(x, y) = p(y, x) except for finitely many x, y ∈ S and p(x, y) corr...
متن کاملExact solution of a heterogeneous multilane asymmetric simple exclusion process.
We have proved an exact solution of a multilane totally asymmetric simple exclusion process (TASEP) with heterogeneous lane-changing rates on a torus. In the expression, the TASEP in each lane and lane-changing transition can be separable. Moreover, the lane-changing transitions satisfy the detailed balance condition, and this is the key to constructing the solution. Using the saddle-point meth...
