On the counting of black hole states in loop quantum gravity
Sergei Alexandrov
We argue that counting black hole states in loop quantum gravity one should take into account only states with the minimal spin at the horizon.

Matrix Quantum Mechanics and Two-dimensional String Theory in Non-trivial Backgrounds
Sergei Alexandrov
String theory is the most promising candidate for the theory unifying all interactions including gravity. It has an extremely difficult dynamics. Therefore, it is useful to study s…

Backgrounds of 2D string theory from matrix model
Sergei Alexandrov
In the Matrix Quantum Mechanical formulation of 2D string theory it is possible to introduce arbitrary tachyonic perturbations. In the case when the tachyonic momenta form a lattic…
