Supersymmetric Generalizations of Matrix Models
jedoch noch nicht hergeleitet werden. Abstract In this thesis generalizations of matrix and eigenvalue models involving supersym-metry are discussed. Following a brief review of the Hermitian one matrix model, the c = −2 matrix model is considered. Built from a matrix valued superfield this model displays supersymmetry on the matrix level. We stress the emergence of a Nicolai–map of this model ...
متن کاملComments on Thermodynamics of Supersymmetric Matrix Models
We present arguments that the structure of the spectrum of the supersymmetric matrix model with 16 real supercharges in the large N limit is rather nontrivial, involving besides the natural energy scale ∼ λ1/3 = (g2N)1/3 also a lower scale ∼ λ1/3N−5/9. This allows one to understand a nontrivial behaviour of the mean internal energy of the system E ∝ T 14/5 predicted by AdS duality arguments.
متن کاملSupersymmetric matrix models and branched polymers
We solve a supersymmetric matrix model with a general potential. While matrix models usually describe surfaces, supersymmetry enforces a cancellation of bosonic and fermionic loops and only diagrams corresponding to so-called branched polymers survive. The eigenvalue distribution of the random matrices near the critical point is of a new kind.
متن کاملSupersymmetric Matrix Models and the Meander Problem
We consider matrix-model representations of the meander problem which describes, in particular, combinatorics for foldings of closed polymer chains. We introduce a supersymmetric matrix model for describing the principal meander numbers. This model is of the type proposed by Marinari and Parisi for discretizing a superstring in D = 1 while the supersymmetry is realized in D = 0 as a rotational ...
متن کاملComments on Supersymmetric Vector and Matrix Models
Some results in random matrices are generalized to supermatrices, in particular superma-trix integration is reduced to an integration over the eigenvalues and the resulting volume element is shown to be equivalent to a one dimensional Coulomb gas of both positive and negative charges.It is shown that,for polynomial potentials, after removing the instability due to the annihilation of opposite c...
