چکیده
A supersymmetric method for the construction of so-called conditionally exactly solvable quantum systems is reviewed and extended to classical stochastic dynamical systems characterized by a Fokker-Planck equation with drift. A class of drift-potentials on the real line as well as on the half line is constructed for which the associated Fokker-Planck equation can be solved exactly. Explicit drift potentials, which describe mono-, bi-, meta-or unstable systems, are constructed and their decay rates and modes are given in closed form.

3 v 1 3 0 O ct 1 99 9 Solution of the quantum inverse problem
We derive a formula that expresses the local spin and field operators of fundamental graded models in terms of the elements of the monodromy matrix. This formula is a quantum analogue of the classical inverse scattering transform. It applies to fundamental spin chains, such as the XYZ chain, and to a number of important exactly solvable models of strongly correlated electrons, such as the super...

There exists an exact relationship between the quasi-exactly solvable problems of quantum mechanics and models of square and rectangular random complex matrices. This relationship enables one to reduce the problem of constructing topological (1/N) expansions in random matrix models to the problem of constructing semiclassical expansions for observ-ables in quasi-exactly solvable problems. Lie a...

Spin coherent states play a crucial role in defining QESM (quasi-exactly solvable models) establishing a strict correspondence between energy spectra of spin systems and low-lying quantum states for a particle moving in a potential field of a certain form. Spin coherent states are also used for finding the Wigner-Kirkwood expansion and quantum corrections to energy quantization rules. The close...

We consider the classical and quantum dynamics in M(atrix) theory. Using a simple ansatz we show that a classical trajectory exhibits a chaotic motion. We argue that the holographic feature of M(atrix) theory is related with the repulsive feature of energy eigenvalues in quantum chaotic system. Chaotic dynamics in N = 2 supersymmetric Yang-Mills theory is also discussed. We demonstrate that aft...

The usual concept of shape invariance is discussed and one extension of this concept is suggested. Gedenshtein [1] defined the “shape invariant” potentials by the relationship V+(x; a0)− V−(x; a1) = W (x, a0) +W ′(x, a0)−W (x; a1) +W ′(x; a1) = R(a1) (1) where W (x; a) is the superpotential, a0 and a1 stand for parameters of the supersymmetric partner potentials V+ and V−, R(a) is a constant.
