[Wen-Chen Chang]

Dear colleagues,

I forward you the notice of a colloquium talk given by Dr. Tetsuo Hatsuda
(RIKEN) in the afternoon of July 15 (Tuesday). The title of his talk "From
Quarks to Neutron Stars" should be of interest to many of you. Welcome to
attend this event.

Best regards,

Wen-Chen

時 間 (Time): July 15, 2025 (Tue.) 14:00

地 點 (Place): 一樓演講廳 1F, Auditorium

演講者 (Speaker): Dr. Tetsuo Hatsuda

所屬機構 (Institute): RIKEN

題 目 (Title): From Quarks to Neutron Stars

摘 要(Abstract):

It is well understood that the most basic building blocks of matter are
elementary particles known as quarks. However, a complete understanding of
how quarks form protons, neutrons, and ultimately atomic nuclei remains an
open problem in physics. Over the past several decades, many neutron stars
have been observed - compact stellar objects with masses similar to that of
the Sun but with radii of only about 10 kilometers. These objects,
sometimes referred to as “giant atomic nuclei,” exist in extreme conditions
that offer valuable opportunities to investigate the behavior of quarks in
dense matter. Understanding the internal structure of neutron stars from a
quark-based perspective has become an important topic that connects
particle physics, nuclear physics, and astrophysics.

In 2017, the merger of two neutron stars was observed, producing a black
hole and emitting gravitational waves. This event marked the beginning of
multi-messenger astronomy and provided a new way to explore the properties
of dense matter. As gravitational wave observations continue to improve,
they may offer new insights into how quarks behave inside neutron stars.

In this talk, I will discuss recent progress in efforts to build a coherent
picture of physical phenomena that span a wide range of scales - from the
microscopic world of quarks to the structure of neutron stars and black
holes - drawing on examples from my own research.
