Circuit Quantisation in Hamiltonian Framework: A Constraint Analysis Approach
Akshat Pandey, Subir Ghosh
In this work we apply Dirac's Constraint Analysis (DCA) to solve Superconducting Quantum Circuits (SQC). The Lagrangian of a SQC reveals the constraints, that are classified in a H…
Measurement-induced phase transitions in systems with diffusive dynamics
Hyunsoo Ha, Akshat Pandey, Sarang Gopalakrishnan +1
The competition between scrambling and projective measurements can lead to measurement-induced entanglement phase transitions (MIPT). In this work, we show that the universality cl…
Critical behavior of dirty parafermionic chains
Akshat Pandey, Aditya Cowsik
A family of -symmetric non-Hermitian models of Baxter was shown by Fendley to be exactly solvable via a parafermionic generalization of the Clifford algebra. We study…
Bipartite Sachdev-Ye Models with Read-Saleur Symmetries
J. Classen-Howes, P. Fendley, A. Pandey +1
We introduce an SU(M)-symmetric disordered bipartite spin model with unusual characteristics. Although superficially similar to the Sachdev-Ye model, it has several markedly differ…
