Diffeomorphism in Closed String Field Theory
Ben Mazel, Charles Wang, Xi Yin
We explain how the spacetime diffeomorphism in the classical bosonic closed string field theory (SFT) is represented as gauge transformations in weakly curved background…

Thermal Bootstrap of Matrix Quantum Mechanics
Minjae Cho, Barak Gabai, Joshua Sandor +1
We implement a bootstrap method that combines stationary state conditions, thermal inequalities, and semidefinite relaxations of matrix logarithm in the ungauged one-matrix quantum…

Rolling tachyon and the Phase Space of Open String Field Theory
Minjae Cho, Ben Mazel, Xi Yin
We construct the symplectic form on the covariant phase space of the open string field theory on a ZZ-brane in c=1 string theory, and determine the energy of the rolling tachyon so…
