Charge and Entanglement Criticality in a U(1)-Symmetric Hybrid Circuit of Qubits
Ahana Chakraborty, Kun Chen, Aidan Zabalo +2
We study critical properties of the entanglement and charge-sharpening measurement-induced phase transitions in a non-unitary quantum circuit evolving with a U(1) conserved charge.…

Memories of initial states and density imbalance in dynamics of interacting disordered systems
Ahana Chakraborty, Pranay Gorantla, Rajdeep Sensarma
We study the dynamics of one and two dimensional disordered lattice bosons/fermions initialized to a Fock state with a pattern of and particles on and sites.…

Non-Equilibrium Field Theory for Dynamics Starting from Arbitrary Athermal Initial Conditions
Ahana Chakraborty, Pranay Gorantla, Rajdeep Sensarma
Schwinger Keldysh field theory is a widely used paradigm to study non-equilibrium dynamics of quantum many-body systems starting from a thermal state. We extend this formalism to d…
