A finite temperature version of the Nagaoka--Thouless theorem in the Hubbard model
Tadahiro Miyao
The Aizenman--Lieb theorem for the Hubbard model expands upon the Nagaoka--Thouless theorem for the ground state to encompass finite temperatures. It can be succin…

Ground state of one-dimensional fermion-phonon systems
Tadahiro Miyao, Seigo Okida, Hayato Tominaga
A new framework for the reflection positivity, based on order-preserving operator inequalities, is proposed. This framework is utilized to investigate one-dimensional fermion-phono…
