Quantum microstate counting from Brownian motion: from many-body systems to black holes
Enzo Bavaro, Javier M. Magan, Leandro Martinek
We introduce a new way to produce infinite families of bases of a quantum system's Hilbert space, as well as methods to find its dimension. These families are constructed via Brown…

Exact Mutual Information Difference: Scalar vs. Maxwell Fields
Nicolás Abate, Horacio Casini, Marina Huerta +1
We compute, for any Rényi index , the exact difference between the mutual Rényi informations of a pair of free massless scalars and that of a Maxwell field in dimensions.…

Optimal symmetry operators
Leandro Martinek
We present a constructive method to maximize the expectation value of operators that implement a symmetry on a subsystem, making use of modular tools. More generally, we study the…
