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…
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…
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…
Imaging the ultrafast coherent control of a skyrmion crystal
Phoebe Tengdin, Benoit Truc, Alexey Sapozhnik +14
Exotic magnetic textures emerging from the subtle interplay between thermodynamic and topological fluctuation have attracted intense interest due to their potential applications in…
Dynamics of visons and thermal Hall effect in perturbed Kitaev models
Aprem P. Joy, Achim Rosch
A vison is an excitation of the Kitaev spin liquid which carries a gauge flux. While immobile in the pure Kitaev model, it becomes a dynamical degree of freedom in th…
