The goal is to explore fundamen tal details regarding the states of ultra-dense matter on the QCD phase di agram that govern the physics of neutron stars (NSs).Multi-messenger obser vations of neutron stars are driving significant efforts to constrain high -density equations of state (EOSs) and are providing critical insights int o the phase structures of ultra-dense matter. These include\, but are not limited to\, the precise determination of pulsar masses through radio obse rvations\, simultaneous mass and radius measurements based on the geometri c and thermal modeling of hotspots on rapidly rotating pulsars\, estimates of surface luminosities from both accreting and isolated neutron stars vi a X-ray emissions\, as well as anticipated neutrino signals from future ga lactic core-collapse supernova events. Most significantly\, gravitational- wave detections from binary neutron star mergers have been leveraged to re fine the range of compactness and tidal deformability of these extremely c ompact objects\, accompanied by the follow-up electromagnetic signals that carry unprecedented information on the composition and properties of thei r neutron-rich ejecta.On the other hand\, recent and planned experiments f rom terrestrial laboratories are playing a pivotal role in setting limits on the low- to intermediate-density EOS and interpreting the transport pro perties of relevant degenerate systems. Furthermore\, advances in theory a nd simulations are providing valuable insights into physical processes in NSs. This includes efforts to identify and characterize observable signatu res of exotic phases—such as hypernuclei and nuclear pasta\, strange hyp erons and kaon/pion condensates\, deconfined quarks\, quarkyonic matter\, stellar superfluidity and superconductivity—and even potential signature s of dark matter particles and physics beyond the standard model (BSM).Int erpreting and connecting these different aspects of study requires a cross -disciplinary endeavor involving communities from various related subfield s\, a primary goal of this workshop. The main program will span from June 6 until June 10\, 2026. Each day will typically feature a few selected tal ks\, followed by ample time for informal\, extensive discussion intended t o exchange ideas and stimulate collaborations. We anticipate 40-50 partici pants from diverse backgrounds to join us\; junior researchers are especia lly encouraged to apply and contribute.The workshop sessions will be condu cted in English\, and the registration fee is 700 RMB per person which inc ludes coffee breaks and lunch. Interested participants should complete the registration form by Friday May 22\, 2026. Lodging will be arranged in a unified manner and the expenses are to be covered by the participants them selves.  Organizing Committee Sophia Han (Tsung-Dao Lee Institute\, Sha nghai Jiao Tong University) Zidu Lin (Sino-French Institute of Nuclear En gineering and Technology\, Sun Yat-Sen University) Shuzhe Shi (Department of Physics\, Tsinghua University) \n\nhttps://indico-tdli.sjtu.edu.cn/ev ent/4949/ LOCATION:Tsung-Dao Lee Institute URL:https://indico-tdli.sjtu.edu.cn/event/4949/ END:VEVENT END:VCALENDAR
