We present a pedagogical discussion of conformally invariant two-dimensional nonlinear sigma models and their relation to string theory. Our main goal is show.

The book contains explanations and descriptions of many details that have been deliberately. (and, I suspect, at times inadvertently) swept under a very large ...
Loop quantum gravity (LQG) is a leading approach toward this goal. At its heart is the central lesson of GR: gravity is a manifestation of spacetime geometry. ...
String theory is an attempt to quantise gravity and unite it with the other fundamental forces of nature. It combines many interesting topics of (quantum) field ...
Quantum gravity was born as that branch of modern theoretical physics that tries to unify its guiding principles, i.e., quantum me- chanics and ...

In each case, quantum mechanics is used to give us appropriate dynamical equations for bulk matter, using the usual rules of quantum statistical ...
Some quantum gravity researchers—especially those from the particle physics community—view the search for a quantum theory of gravity as tantamount to the ...
For supersymmetric orbifold compactifications, we apply machine learning methods to improve the search for MSSM-like string models. We use autoencoder neural ...
