Article Synopsis
- A systematic review of 43 studies involving over 1.6 million patients analyzed the frequency and outcomes of atypical presentations in acute coronary syndrome (ACS).
- The findings indicated that about 11.6% of patients presented atypically (without classic chest pain), with rates varying widely; up to 33.6% of patients had no chest pain at all.
- Factors increasing the likelihood of atypical presentation included non-ST-elevation myocardial infarction, greater Killip class, and a history of heart failure, with patients presenting atypically facing double the mortality risk compared to those with typical symptoms.
We propose the strongly tilted Bose-Hubbard model as a natural platform to explore Hilbert-space fragmentation (HSF) and fracton dynamics in two dimensions in a setup and regime readily accessible in optical lattice experiments. Using a perturbative ansatz, we find HSF when the model is tuned to the resonant limit of on-site interaction and tilted potential. First, we investigate the quench dynamics of this system and observe numerically that the relaxation dynamics strongly depends on the chosen initial state-one of the key signatures of HSF.

Quantum systems out of equilibrium typically relax to thermal equilibrium states by scrambling local information and building up entanglement entropy. However, kinetic constraints in the Hamiltonian can lead to a breakdown of this fundamental paradigm owing to a fragmentation of the underlying Hilbert space into dynamically decoupled subsectors in which thermalization can be strongly suppressed.
