Decay rates of almost strong modes in Floquet spin chains beyond Fermi's Golden Rule
Hsiu-Chung Yeh, Achim Rosch, Aditi Mitra
The stability and dynamics of almost strong zero and modes in weakly non-integrable Floquet spin chains are investigated. Such modes can also be viewed as localized Majorana mo…
Universal phenomenology at critical exceptional points of nonequilibrium models
Carl Philipp Zelle, Romain Daviet, Achim Rosch +1
In thermal equilibrium the dynamics of phase transitions is largely controlled by fluctuation-dissipation relations: On the one hand, friction suppresses fluctuations, while on the…
Non-integrable Floquet Ising model with duality twisted boundary conditions
Aditi Mitra, Hsiu-Chung Yeh, Fei Yan +1
Results are presented for a Floquet Ising chain with duality twisted boundary conditions, taking into account the role of weak integrability breaking in the form of four-fermion in…
First Order Quantum Phase Transition in the Hybrid Metal-Mott Insulator Transition Metal Dichalcogenide 4Hb-TaS2
Abhay Kumar Nayak, Aviram Steinbok, Yotam Roet +8
Coupling together distinct correlated and topologically non-trivial electronic phases of matter can potentially induce novel electronic orders and phase transitions among them. Tra…
Experimental observation of one-dimensional motion of interstitial skyrmion in FeGe
Dongsheng Song, Weiwei Wang, Jie-Xiang Yu +11
The interplay between dimensionality and topology manifests in magnetism via both exotic texture morphology and novel dynamics. A free magnetic skyrmion exhibits the skyrmion Hall…
Network of chiral one-dimensional channels and localized states emerging in a moiré system
Jeyong Park, Lasse Gresista, Simon Trebst +2
Moiré systems provide a highly tunable platform for engineering band structures and exotic correlated phases. Here, we theoretically study a model for a single layer of graphene su…
