Quench induced collective excitations: from breathing to acoustic modes
Shicong Song, Ke Wang, Zhengli Wu +3
In trapped Bose-Einstein condensates, interaction quenches which are abrupt changes of the interaction strength typically implemented via Feshbach tuning, are a practical and widel…

Properties of 4D spinfoam quantum geometry: Results from next-to-leading order spinfoam large- asymptotics of 1-5 Pachner move
Haida Li, Muxin Han, Hongguang Liu +2
This paper proposes several criteria to probe the non-trivialities of 4-dimensional geometry that impact spinfoam amplitude. These criteria include the standard deviation of 4-volu…
