Locality forces equal energy spacing of quantum many-body scar towers
Nicholas O'Dea, Lei Gioia, Sanjay Moudgalya +1
Quantum many-body scars are non-thermal eigenstates embedded in the spectra of otherwise non-integrable Hamiltonians. Paradigmatic examples often appear as quasiparticle towers of…
Entanglement Oscillations from Many-Body Quantum Scars
Nicholas O'Dea, Adithya Sriram
Quantum scars are nonthermal eigenstates that prevent thermalization of initial states with weight on the scars. When the scar states are equally spaced in energy, superpositions o…
Absorbing state transitions with long-range annihilation
Nicholas O'Dea, Sayak Bhattacharjee, Sarang Gopalakrishnan +1
We introduce a family of classical stochastic processes describing diffusive particles undergoing branching and long-range annihilation in the presence of a parity constraint. The…
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…
