Scaling vs entanglement in measurement-induced phase transition for non-integrable systems
Paranjoy Chaki, Protyush Nandi, Subinay Dasgupta +1
We find that the measurement-induced phase transition generated by deterministic global measurements, previously observed in the integrable transverse-field Ising model (TFIM), per…

Spread complexity as a probe in generalized and long-range Aubry-Andre-Harper models
Triyas Sapui, Tanoy Kanti Konar, Subinay Dasgupta +1
We investigate the spread complexity of quantum quenches in generalized and long-range Aubry-Andre-Harper (AAH) models, encompassing regimes with and without mobility edges. In par…

Disappearance of measurement-induced phase transition in a quantum spin system for large sizes
Paranjoy Chaki, Protyush Nandi, Ujjwal Sen +1
Measurement-induced phase transitions are often studied in random quantum circuits, with local measurements performed with a certain probability. We present here a model where a gl…
