Control transition in a temporally random classical spin chain
Elisha Shmalo, J. H. Pixley, Manas Kulkarni +2
We theoretically explore a phase transition between controlled and chaotic dynamics in a classical spin chain model subject to chaotic Hamiltonian dynamics and a contractive "contr…
Spectral properties and coding transitions of Haar-random quantum codes
Grace M. Sommers, J. Alexander Jacoby, Zack Weinstein +2
A quantum error-correcting code with a nonzero error threshold undergoes a mixed-state phase transition when the error rate reaches that threshold. We explore this phase transition…
Scalable accuracy gains from postselection in quantum error correcting codes
Hongkun Chen, Daohong Xu, Grace M. Sommers +3
Decoding stabilizer codes such as the surface and toric codes involves evaluating free-energy differences in a disordered statistical mechanics model, in which the randomness comes…
Infinitely fast critical dynamics: Teleportation through temporal rare regions in monitored quantum circuits
Gal Shkolnik, Sarang Gopalakrishnan, David A. Huse +2
We consider measurement-induced phase transitions in monitored quantum circuits with a measurement rate that fluctuates in time, remaining spatially uniform at each time. The spati…
Observation of Magnon-Polarons in the Fermi-Hubbard Model
Max L. Prichard, Zengli Ba, Ivan Morera +4
The interplay of magnetic excitations and itinerant charge carriers is a ubiquitous phenomenon in strongly correlated electron systems. In the vicinity of magnetically ordered phas…
