We develop an effective field theory of QCD and QCD-like theories beyond the Standard
Model, based on the hidden local symmetry (HLS) model for the pseudoscalar mesons (π) …

We review theoretical approaches to explore the phase diagram of nuclear and quark matter
at high baryon density. We first look over the basic properties of quantum chromodynamics …

The QCD vacuum shows the dynamical breaking of chiral symmetry. In the hot and/or dense
QCD medium, the chiral order parameter such as⟨ q¯ q⟩ is expected to change as a …

This article reviews our view on how chiral symmetry, its pattern of breaking and restoration
under extreme conditions manifest themselves in the nucleon, nuclei, nuclear matter and …

We propose that effective field theories for nuclei and nuclear matter comprise of “double
decimation”:(1) the chiral symmetry decimation (CSD) and (2) Fermi liquid decimation (FLD) …

We review the chiral variant and invariant components of nucleon masses and the
consequence of their existence on the chiral restoration in extreme conditions, particularly in …

We propose “vector manifestation”(VM) of the Wigner realization of chiral symmetry in which
the symmetry is restored at the critical point by the massless degenerate pion (and its flavor …

This article is based on a series of lectures given at ELAF 93 on the description of low-
energy hadronic systems in and out of hadronic medium. The focus is put on identifying, with …

We describe the in-medium properties of hadrons in dense matter near chiral restoration
using a Wilsonian matching to QCD of an effective field theory with hidden local symmetry at …

In continuation of our systematic effort to understand hadronic matter at high density, we
study dense skyrmion matter and its chiral phase structure in an effective field theory …
