Micro-Macro Duality in Quantum Physics
Izumi Ojima
Micro-Macro Duality means here the universal mutual relations between the microscopic quantum world and various macroscopic classical levels, which can be formulated mathematically…
p-Nuclearity in a New Perspective
Christopher J. Fewster, Izumi Ojima, Martin Porrmann
In this paper we try to settle some confused points concerning the use of the notion of p-nuclearity in the mathematical and physical literature, pointing out that the nuclearity i…
Temparature as Order Parameter of Broken Scale Invariance
Izumi Ojima
In algebraic quantum field theory the (inverse) temperature is shown to be a macroscopic \textit{order parameter} to parametrize mutually disjoint thermal \textit{sectors} arising…
A Unified Scheme for Generalized Sectors based on Selection Criteria --Order parameters of symmetries and of thermality and physical meanings of adjunctions--
Izumi Ojima
A unified scheme for treating generalized superselection sectors is proposed on the basis of the notion of selection criteria to characterize states of relevance to each specific d…
A Unified Scheme for Generalized Sectors based on Selection Criteria. I. Thermal situations, unbroken symmetries and criteria as classifying categorical adjunctions
I. Ojima
A unified scheme for treating generalized superselection sectors is proposed on the basis of the notion of selection criteria to characterize states of relevance to each specific d…
A Unified Scheme for Generalized Sectors based on Selection Criteria. II. Spontaneously broken symmetries and some basic notions in quantum measurements
I. Ojima
Continuing the analysis in a unified scheme for treating generalized superselection sectors based upon the notion of selection criteria for states of relevance in quantum physics,…
