A Tale of Two Hungarians: Tridiagonalizing Random Matrices
Vijay Balasubramanian, Javier M. Magan, Qingyue Wu
The Hungarian physicist Eugene Wigner introduced random matrix models in physics to describe the energy spectra of atomic nuclei. As such, the main goal of Random Matrix Theory (RM…
Geometry of Krylov Complexity
Pawel Caputa, Javier M. Magan, Dimitrios Patramanis
We develop a geometric approach to operator growth and Krylov complexity in many-body quantum systems governed by symmetries. We start by showing a direct link between a unitary ev…
Quantum Complementarity through Entropic Certainty Principles
Javier M. Magan, Diego Pontello
We approach the physical implications of the non-commutative nature of Complementary Observable Algebras (COA) from an information theoretic perspective. In particular, we derive a…
On operator growth and emergent Poincaré symmetries
Javier M. Magan, Joan Simon
We consider operator growth for generic large-N gauge theories at finite temperature. Our analysis is performed in terms of Fourier modes, which do not mix with other operators as…
On the logarithmic coefficient of the entanglement entropy of a Maxwell field
Horacio Casini, Marina Huerta, Javier M. Magan +1
We elucidate the mismatch between the -anomaly coefficient and the coefficient of the logarithmic term in the entanglement entropy of a Maxwell field. In contrast to the usual a…
Complexity measures in QFT and constrained geometric actions
Pablo Bueno, Javier M. Magan, C. S. Shahbazi
We study the conditions under which, given a generic quantum system, complexity metrics provide actual lower bounds to the circuit complexity associated to a set of quantum gates.…
