Engineering correlated phases through manipulation of Van Hove singularities
Thomas P. Sheerin, Maria Ramirez, Chris A. Hooley +1
Controlling the ordered phases of correlated electron systems remains a central challenge in quantum materials design. Divergences in the electronic density of states, known as Van…
Counting Edge Modes with the Higher Berry Curvature: A Bulk Topological Order Parameter for Quantum Spin Chains
Adam J. McRoberts, Joe Crossley, Chris Hooley +1
We show that the higher Berry curvature (HBC) can be used to count the gapless edge modes created by an entanglement cut, and thus defines an integer-valued topological order param…
Transition between critical antiferromagnetic phases in the - spin chain
Adam J. McRoberts, Chris Hooley, A. G. Green
The - spin chain is one of the canonical models of quantum magnetism, and has long been known to host a critical antiferromagnetic phase with power-law decay of spin corr…
Stochastic resetting in discrete-time quantum dynamics: steady states and correlations in few-qubit systems
Sascha Wald, Louie Hong Yao, Thierry Platini +2
Time evolution in several classes of quantum devices is generated through the application of quantum gates. Resetting is a critical technological feature in these systems allowing…
