The High Energy Photon Source (HEPS) is a 6-GeV, kilometer-scale, ultralow-emittance storage ring light source to be built in Beijing, China. The HEPS is now under extensive design and study. In this report we will introduce the progress of the lattice design and related physics studies on HEPS, covering issues of storage ring design, booster design, injection design, collective effects, error study, insertion device effects, longitudinal dynamics, etc.
