Experimental observation of coherent oscillations in a Rydberg atom chain [H. Bernien et al., Nature (London) 551, 579 (2017)] has led to the discovery quantum many-body scars (QMBSs) which is new paradigm for ergodicity breaking. The experimental findings can be well captured by kinetically constrained model called ``PXP'' model, been shown host eigenstate thermalization hypothesis (ETH)-viola...

Processing of time intervals in short temporal ranges, typically in suband suprasecond intervals, is vital for the survival of primates and humans. Research evidence has already shown that the processing of suband supra-second intervals is subserved by different neural mechanisms (Buhusi and Meck, 2005). In the domain of time perception, one outstanding scientific question remains to be solved ...
