From stable periodic orbits to many-body chaos: doubly tunable prethermalization via engineering of an emergent band structure
Jianan Wang, Yang Hou, Andrea Pizzi +3
We uncover a family of many-body periodic orbits in a periodically driven (Floquet) spin system away from the high-frequency limit. While linear stability analysis predicts that pe…
Floquet Superheating
Yang Hou, Andrea Pizzi, Huike Jin +3
Periodically driven many-body systems generally heat towards a featureless 'infinite-temperature' state. As an alternative to uniform heating in a clean system, here we establish a…
Emergent long-tail dynamics in driven magnets with dynamical frustration
Chenyue Guo, Hongzheng Zhao, Zi Cai
In this study, we show that dynamical frustration can spontaneously emerge in frustration-free magnetic systems under periodic driving. Specifically, we consider a classical spin s…
Complex and tunable heating in conformal field theories with structured drives via classical ergodicity breaking
Liang-Hong Mo, Roderich Moessner, Hongzheng Zhao
Emission and absorption of energy are fundamental aspects of non-equilibrium dynamics. The heating induced by driving a many-body system is perhaps the most straightforward diagnos…
Floquet-engineered Emergent Massive Nambu-Goldstone Modes
Yang Hou, Zhanpeng Fu, Roderich Moessner +2
We present a general framework to implement massive Nambu-Goldstone quasi-particles in driven many-body systems. The underlying mechanism leverages an explicit Lie group structure…
Non-Hermitian delocalization in 1D via emergent compactness
Liang-Hong Mo, Zhenyu Xiao, Roderich Moessner +1
Potential disorder in 1D leads to Anderson localization of the entire spectrum. Upon sacrificing hermiticity by adding non-reciprocal hopping, the non-Hermitian skin effect compete…
