We summarize recent developments of supersymmetric quantum mechanics. We start from the susy oscillator, mention the factorization schemes and discuss the order of levels of schrödinger operators as an example. We mention soliton equations and the inverse scattering problem and discuss susy breaking and index problems for dirac operators.
Summary of supersymmetry twentieth century physics has witnessed two major paradigm shifts in the manner we know nature. The first is quantum mechanics, and yet another is relativity. The wedding backward and forward, known as quantum field theory, created an enfant terrible, namely anti-matter.

The general idea of susyqm (super symmetric quantum mechanics) is the introduction of the so- called superpotential which gives rise to two partner potentials with the same eigenspectrum except for one ground level. So instead of getting the spectrum from a given potential, here you can arrive at the potentials from a given spectrum.
Supersymmetric extension by making the fermionic variables complex. This way we can study a one-dimensional particle that interacts with a potential, and find the associated conserved charge. Finally i will quantize the supersymmetric theory so that we will find a su-persymmetric quantum mechanical theory.

Along the years, supersymmetric quantum mechanics (susy qm) has been used for studying solvable quantum potentials. It is the simplest method to build hamiltonians with prescribed spectra in the spectral design. The key is to pair two hamiltonians through a finite order differential operator. Some related subjects can be simply analyzed, as the algebras ruling both hamiltonians and the associated coherent states.
Supersymmetric quantum mechanics, which describes a supersymmetric particle moving on a compact riemannian manifold, has been studied by many.
In concrete realizations, the class includes supersymmetric quantum mechanical models associated with one-dimensional or radial schrodinger operators with potentials of a special type, called shape-invariant potentials in the physics literature. Introduction and the main result in this paper, we present in an abstract framework a class of supersym- metric quantum mechanics (ssqm) whose eigenvalue problem is (in part) exactly solvable.
The hamiltonian is a sum of kinetic and potential contri-butions, each of which is non-negative, so the lowest energy field configuration will come from a configuration a 0 that sits in the minimum of the potential throughout space.

As we will soon see, it turned out that susy quantum mechanics has many interesting results itself.
We present the general ideas on supersymmetric quantum mechanics (susy-qm) using different representations for the operators in question, which are defined by the corresponding bosonic hamiltonian as part of susy hamiltonian and its supercharges, which are defined as matrix or differential operators. We show that, although most of the susy partners of one-dimensional schrödinger problems have.

We consider schwinger's method of angular momentum addition using the su (2) algebra with both a fermionic and a bosonic oscillator. We show that the total spin states obtained are: one boson singlet state and an arbitrary number of spin-1/2 states, the later ones are energy degenerate. It means that we have in this case supersymmetric quantum mechanics and also the addition of angular momentum for massless particles.
This invaluable book provides an elementary description of supersymmetric quantum mechanics which complements the traditional coverage found in the existing quantum mechanics textbooks. It gives physicists a fresh outlook and new ways of handling quantum-mechanical problems, and also leads to improved approximation techniques for dealing with potentials of interest in all branches of physics.

We review solvable models within the framework of supersymmetric quantum mechanics (susyqm). In susyqm, the shape invariance condition insures solvability of quantum mechanical problems. We review shape invariance and its connection to a consequent potential algebra. The additive shape invariance condition is specified by a difference-differential equation; we show that this equation is equivalent to an infinite set of partial differential equations.
Indeed, many remarkable properties of string theory have been explained using supersymmetry as a tool. In this dissertation, we review the basic formulation of supersymmetric quantum mechanics starting with introducing the concepts of supercharges and superalgebra. We show that, if there is a supersymmetric state, it is the zero-energy ground state.
