Bayesian phase transition for the critical Ising model: Enlarged replica symmetry in the epsilon expansion and in 2D
Kay Joerg Wiese, Alapan Das, Adam Nahum
A process that images or measures bond energies in the critical Ising model can be in distinct measurement ``phases'', depending on the precision of measurement. We study the trans…

Bayesian critical points in classical lattice models
Adam Nahum, Jesper Lykke Jacobsen
The Boltzmann distribution encodes our subjective knowledge of the configuration in a classical lattice model, given only its Hamiltonian. If we acquire further information about t…

Monitored fermions with conserved charge
Michele Fava, Lorenzo Piroli, Denis Bernard +1
We study measurement-induced phases of free fermion systems with U(1) symmetry. Following a recent approach developed for Majorana chains, we derive a field theory description for…
