String Theory is one of the most successful attempts to quantitze gravity. The extended nature of the string (as opposed to the point particle nature in quantum field theory), regularizes the the nonrenormalizable UV divergencies of General Relativity, which itself is recovered as the effective theory in the low energy limit.  Furthermore, String Theory naturally includes the building blocks of the standard model of particle physics, gauge fields and chiral fermions, as low energy degrees of freedoms. String Theory hence is a unified theory of gravity and quantum field theory. This lecture, which builds up onto my lecture String Theory I, considers the following advanced concepts of supersymmetric string theory:

1) Review of the bosonic string 

2) Clifford algebras in diverse dimensions, fermionic fields

3) Supersymmetry in two and more dimensions

4) Classical and quantized Ramond-Neveau-Schwarz Type IIA/IIB Superstring 

5) Type I and Heterotic Superstring Theories

6) Dualities between different superstring theories and M Theory in eleven dimensions

7) D-Branes and supersymmetric gauge theories

8) Supergravity and the AdS/CFT Correspondence
