Learning Potts Models and Toric Codes: Higher and Ordinary Nishimori Criticality
Rushikesh A. Patil, Malte Pütz, Rohit Mukherjee +3
Motivated by a previous Ising study, we identify a Nishimori line in the learning phase diagram of the -state Potts model under bond-energy m…
Universal crossovers in weakly-monitored quantum critical states
Abhishek Kumar, Rushikesh A. Patil, Andreas W. W. Ludwig +1
We study post-measurement ensembles of ground states of tricritical and critical 1D quantum Ising Hamiltonians subjected, respectively, to weak energy and spin measurements without…
Higher Nishimori Criticality and Exact Results at the Learning Transition of Deformed Toric Codes
Rushikesh A. Patil, Malte Pütz, Simon Trebst +2
We revisit a learning-induced tricritical point, at which three phases with strong, weak, and broken symmetry meet, in the phase diagram of a deformed toric code wavefunction…
Shannon entropy of the measurement record at measurement-dominated criticality and RG flow: A c-theorem for effective central charge and a g-theorem for effective boundary entropy
Rushikesh A. Patil, Andreas W. W. Ludwig
We present two theorems demonstrating non-perturbatively the decrease under relevant renormalization group (RG) flow of two quantities, and charac…
Highly complex novel critical behavior from the intrinsic randomness of quantum mechanical measurements on critical ground states -- a controlled renormalization group analysis
Rushikesh A. Patil, Andreas W. W. Ludwig
We consider the effects of weak measurements on the quantum critical ground state of the one-dimensional (a) tricritical and (b) critical quantum Ising model, by measuring in (a) t…
Real-space entanglement spectra of parton states in fractional quantum Hall systems
Abhishek Anand, Rushikesh A. Patil, Ajit C. Balram +1
Real-space entanglement spectra (RSES) capture characteristic features of the topological order encoded in the fractional quantum Hall (FQH) states. In this work, we numerically co…
