چکیده

Following the program, proposed in hep-th/0310113, of systematizing known properties of matrix model partition functions (defined as solutions to the Virasoro-like sets of linear differential equations), we proceed to consideration of non-Gaussian phases of the Hermitean one-matrix model. A unified approach is proposed for description of “connected correlators” in the form of the phaseindependent “check-operators” acting on the small space of T -variables (which parameterize the polynomialW (z)). With appropriate definitions and ordering prescriptions, the multidensity checkoperators look very similar to the Gaussian case (however, a reliable proof of suggested explicit expressions in all loops is not yet available, only certain consistency checks are performed).

Amplification or reduction of backscattering in a coherently amplifying or absorbing disordered chain

We study localization properties of a one-dimensional disordered system characterized by a random non-hermitean hamiltonian where both the randomness and the non-hermiticity arises in the local site-potential; its real part being random, and a constant imaginary part implying the presence of either a coherent absorption or amplification at each site. While the two-probe transport properties beh...

Universal Wide Correlators in Non-gaussian Orthogonal, Unitary and Symplectic Random Matrix Ensembles

We calculate wide distance connected correlators in non-gaussian orthogonal , unitary and symplectic random matrix ensembles by solving the loop equation in the 1/N-expansion. The multi-level correlator is shown to be universal in large N limit. We show the algorithm to obtain the connected correlator to an arbitrary order in the 1/N-expansion.

Replica Method for Wide Correlators in Gaussian Orthogonal, Unitary and Symplectic Random Matrix Ensembles

We calculate connected correlators in Gaussian orthogonal, unitary and symplectic random matrix ensembles by the replica method in the 1/N-expansion. We obtain averaged one-point Green's functions up to the next-to-leading order O(1/N) and wide two-level correlators up to the first non-trivial order O(1/N 2) by carefully treating fluctuations in saddle-point evaluation .

Eigenvalue Correlations in Ginibre's Non-hermitean Random Matrices at Β = 4

Correlation function of complex eigenvalues of N × N random matrices drawn from Ginibre's non-Hermitean ensemble of symplectic symmetry is given in terms of a quaternion determinant. Spectral properties of Gaussian ensembles are studied in detail in the regimes of weak and strong non-Hermiticity.

Diagrammatic Method for Wide Correlators in Gaussian Orthogonal and Symplectic Random Matrix Ensembles

We calculate connected correlators in time dependent Gaussian orthogonal and symplectic random matrix ensembles by a diagrammatic method. We obtain averaged one-point Green's functions in the leading order O(N 0) and wide two-level and three-level correlators in the first nontrivial order by summing over twisted and untwisted planer diagrams. Introduction Recently, Brézin and Zee pointed out th...
