WebMay 14, 2024 · We show that many-body scars appear in the Fibonacci chain, a model with a constrained local Hilbert space that has recently been experimentally realized in a … WebIn most quantum sensing schemes, interactions between the constituent particles of the sensor are expected to degrade sensitivity. We show that the phenomenon of many-body scarring can be exploited for quantum sensing that is robust against certain strong interactions. In the ideal case of perfect scars with harmonic energy gaps, the optimal …

WebNov 6, 2024 · I will present simple structure underlying many models with quantum many-body scar towers such as the AKLT chain and the spin-1 XY model. In the latter case, the mechanism can be also stated as a particular removal of symmetry, and I will discuss new examples of electronic extended Hubbard models with eta-pairing states as true scars … WebOct 25, 2024 · Strongly interacting systems with quantum many-body scars exhibit persistent fidelity oscillations when prepared in a certain class of initial states, but otherwise undergo ergodic dynamics. Previous examples of scars have interpreted the characteristic periodic dynamics in terms of the precession of a macroscopic SU(2) spin in an effective … overalls youtube
