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…

Topological materials with extensive flat-band surface states
Protyush Nandi, Subinay Dasgupta
Materials that have zero-energy flat band states on the surface may show surface superconductivity. Here we report a theoretical observation that a Hamiltonian describing a thin sl…
