Asymptotics of the partition function of a random matrix model
Pavel M. Bleher, Alexander Its (2005)
Annales de l’institut Fourier
Similarity:
We prove a number of results concerning the large asymptotics of the free energy of a random matrix model with a polynomial potential. Our approach is based on a deformation of potential and on the use of the underlying integrable structures of the matrix model. The main results include the existence of a full asymptotic expansion in even powers of of the recurrence coefficients of the related orthogonal polynomials for a one-cut regular potential and the double scaling asymptotics...

Semiclassics of the quantum current in very strong magnetic fields
Soren Fournais (2002)
Annales de l’institut Fourier
Similarity:
We prove a formula for the current in an electron gas in a semiclassical limit corresponding to strong, constant, magnetic fields. Little regularity is assumed for the scalar potential . In particular, the result can be applied to the mean field from magnetic Thomas-Fermi theory . The proof is based on an estimate on the density of states in the second Landau band.
