## Contribution

It uncovers new collective modes and spectral phenomena in quark-gluon plasma near phase transitions, highlighting the impact of soft modes on quark spectra.

## Key findings

- Non-Fermi liquid behavior near color superconducting transition
- Pseudogap formation in quark density of states
- Emergence of three collective excitations in chiral transition

## Abstract

We investigate the quark spectrum in the quark-gluon plasma phase near color superconducting (CS) and chiral phase transitions. Owing to the precursory soft modes of the phase transitions, there appear novel excitaion spectra: In the CS transition, the quark matter shows non-Fermi liquid behavior and leads to the pseudogap in the density of states of quarks. In the chiral transition, three collective excitations appear in the quark spectrum.
