Informational and algebraic renormalization group
Takato Mori, Teruaki Nagasawa
Renormalization group (RG) is a core concept in physics from statistical mechanics to quantum field theory, yet its schemes differ widely between field theory and many-body physics…
Quantifying Measurement Objectivity: A Retrodictive Approach
Jiaxi Kuang, Teruaki Nagasawa, Kensei Torii +1
When can one interpret the outcomes of a quantum measurement as revealing a pre-existing objective property? Using the recently developed formalism of quantum measurement retrodict…
Macroscopicity and observational deficit in states, operations, and correlations
Teruaki Nagasawa, Eyuri Wakakuwa, Kohtaro Kato +1
To understand the emergence of macroscopic irreversibility from microscopic reversible dynamics, the idea of coarse-graining plays a fundamental role. In this work, we develop a un…
On the generic increase of observational entropy in isolated systems
Teruaki Nagasawa, Kohtaro Kato, Eyuri Wakakuwa +1
Observational entropy -- a quantity that unifies Boltzmann's entropy, Gibbs' entropy, von Neumann's macroscopic entropy, and the diagonal entropy -- has recently been argued to pla…
