A local description of strong symmetries and strong-to-weak symmetry breaking in quantum many-body systems
Ruizhi Liu, Jinmin Yi, Dominic V. Else
In mixed states of quantum systems, symmetries come in two types: strong and weak. Furthermore, it has been argued that in quantum many-body systems, strong symmetries can be "spon…
Observation of a prethermal discrete time crystal
Antonis Kyprianidis, Francisco Machado, William Morong +9
The conventional framework for defining and understanding phases of matter requires thermodynamic equilibrium. Extensions to non-equilibrium systems have led to surprising insights…
An improved Lieb-Robinson bound for many-body Hamiltonians with power-law interactions
Dominic V. Else, Francisco Machado, Chetan Nayak +1
In this work, we prove a new family of Lieb-Robinson bounds for lattice spin systems with long-range interactions. Our results apply for arbitrary -body interactions, so long as…
Exponentially Slow Heating in Short and Long-range Interacting Floquet Systems
Francisco Machado, Gregory D. Meyer, Dominic V. Else +2
We analyze the dynamics of periodically-driven (Floquet) Hamiltonians with short- and long-range interactions, finding clear evidence for a thermalization time, , that increas…
Symmetry protection of measurement-based quantum computation in ground states
Dominic V. Else, Stephen D. Bartlett, Andrew C. Doherty
The two-dimensional cluster state, a universal resource for measurement-based quantum computation, is also the gapped ground state of a short-ranged Hamiltonian. Here, we examine t…
Symmetry-protected phases for measurement-based quantum computation
Dominic V. Else, Ilai Schwarz, Stephen D. Bartlett +1
Ground states of spin lattices can serve as a resource for measurement-based quantum computation. Ideally, the ability to perform quantum gates via measurements on such states woul…
