Quantum scars from holographic boson stars
Yan Liu, Ya-Wen Sun, Yuan-Tai Wang
Quantum many-body scars are atypical nonthermal states embedded in the chaotic spectrum that evade conventional ergodicity. We propose the asymptotically AdS mini-boson star as a h…
Holographic Schwinger-Keldysh effective field theories including a non-hydrodynamic mode
Yan Liu, Ya-Wen Sun, Xin-Meng Wu
We derive the Schwinger-Keldysh effective field theories for diffusion including the lowest non-hydrodynamic degree of freedom from holographic Gubser-Rocha systems. At low tempera…
Generalized Rindler Wedge and Holographic Observer Concordance
Xin-Xiang Ju, Wen-Bin Pan, Ya-Wen Sun +1
Defining gravitational subsystems has long been challenging due to the lack of the conventional notion of locality in gravity. In this work, we define gravitational subsystems from…
Topological phase transitions of semimetal states in effective field theory models
Xuanting Ji, Ya-Wen Sun
Effective relativistic field theory models capable of realizing various gapless topological states are presented in this work. We study the topological phase transitions of the Wey…
