Matrix Thermodynamic Uncertainty Relation for Non-Abelian Charge Transport
Domingos S. P. Salazar
Thermodynamic uncertainty relations (TURs) bound the precision of currents by entropy production, but quantum transport of noncommuting (non-Abelian) charges challenges standard fo…

Universal Thermodynamic Uncertainty Relation for Quantum Divergences
Domingos S. P. Salazar
We show that any Petz -divergence (where is operator convex) between quantum states admits a universal -mixture representation: the distinguishability of from $Ï…
