Entanglement dynamics in hybrid quantum circuits
Andrew C. Potter, Romain Vasseur
The central philosophy of statistical mechanics (stat-mech) and random-matrix theory of complex systems is that while individual instances are essentially intractable to simulate,…
Field theory of charge sharpening in symmetric monitored quantum circuits
Fergus Barratt, Utkarsh Agrawal, Sarang Gopalakrishnan +3
Monitored quantum circuits (MRCs) exhibit a measurement-induced phase transition between area-law and volume-law entanglement scaling. MRCs with a conserved charge additionally exh…
Gate-tunable heavy fermion quantum criticality in a moiré Kondo lattice
Ajesh Kumar, Nai Chao Hu, Allan H. MacDonald +1
We propose a realization of Kondo-lattice physics in moiré superlattices at the interface between a WX homobilayer and MoX monolayer (where X=S,Se). Under appropriate gatin…
Reply to Comment on "Discrete Time Crystals: Rigidity Criticality and Realizations"
Norman Y. Yao, Andrew C. Potter, Ionut-Dragos Potirniche +1
This is a reply to the comment from Khemani, Moessner and Sondhi (KMS) [arXiv:2109.00551] on our manuscript [Phys. Rev. Lett. 118, 030401 (2017)]. The main new claim in KMS is that…
Realizing a dynamical topological phase in a trapped-ion quantum simulator
Philipp T. Dumitrescu, Justin Bohnet, John Gaebler +6
Nascent platforms for programmable quantum simulation offer unprecedented access to new regimes of far-from-equilibrium quantum many-body dynamics in (approximately) isolated syste…
Entanglement and charge-sharpening transitions in U(1) symmetric monitored quantum circuits
Utkarsh Agrawal, Aidan Zabalo, Kun Chen +5
Monitored quantum circuits can exhibit an entanglement transition as a function of the rate of measurements, stemming from the competition between scrambling unitary dynamics and d…
