A comment on "Discrete time crystals: rigidity, criticality, and realizations"
Vedika Khemani, Roderich Moessner, S. L. Sondhi
The Letter by N. Y. Yao et. al. [1,2] presents three models for realizing a many-body localized discrete time-crystal (MBL DTC): a short-ranged model [1], its revised version [2],…
Tri-unitary quantum circuits
Cheryne Jonay, Vedika Khemani, Matteo Ippoliti
We introduce a novel class of quantum circuits that are unitary along three distinct "arrows of time". These dynamics share some of the analytical tractability of "dual-unitary" ci…
Postselection-free entanglement dynamics via spacetime duality
Matteo Ippoliti, Vedika Khemani
The dynamics of entanglement in `hybrid' non-unitary circuits (for example, involving both unitary gates and quantum measurements) has recently become an object of intense study. A…
Perturbative instability towards delocalization at phase transitions between MBL phases
Sanjay Moudgalya, David A. Huse, Vedika Khemani
We examine the stability of marginally Anderson localized phase transitions between localized phases to the addition of many-body interactions, focusing in particular on the spin-g…
From tunnels to towers: quantum scars from Lie Algebras and q-deformed Lie Algebras
Nicholas O'Dea, Fiona Burnell, Anushya Chandran +1
We present a general symmetry-based framework for obtaining many-body Hamiltonians with scarred eigenstates that do not obey the eigenstate thermalization hypothesis. Our models ar…
Entanglement phase transitions in measurement-only dynamics
Matteo Ippoliti, Michael J. Gullans, Sarang Gopalakrishnan +2
Unitary circuits subject to repeated projective measurements can undergo an entanglement phase transition (EPT) as a function of the measurement rate. This transition is generally…
