Mixed-State Phase Transitions in Measurement-Dressed Imaginary-Time Evolution

Yi-Ming Ding, Zenan Liu, Xu Tian +3

Motivated by the ubiquity of decoherence in quantum hardware and the growing role of imaginary-time evolution (ITE) in quantum algorithms, we investigate how many-body correlations…

Spontaneous continuous-symmetry breaking and tower of states in a comb chain

Jingya Wang, Zenan Liu, Bin-Bin Mao +4

Based on the study of a one-dimensional (1D) antiferromagnetic Heisenberg model on a comb lattice, this work identifies an example of spontaneous continuous symmetry breaking in a…

On entropy of $Φ$ -irregular and $Φ$ -level sets in maps with the shadowing property

Magdalena Foryś-Krawiec, Jiri Kupka, Piotr Oprocha +1

We study the properties of $Φ$ -irregular sets (sets of points for which the Birkhoff average diverges) in dynamical systems with the shadowing property. We estimate the topological…
