Essentially exact numerical modelling of flux qubit chains subject to charge and flux noise
Matthew R. C. Fitzpatrick, Jack Raymond, Malcolm P. Kennett
We present an essentially exact numerical method for modelling flux qubit chains subject to charge and flux noise. We define an essentially exact method as one that introduces erro…

Phase and group velocities for correlation spreading in the Mott phase of the Bose-Hubbard model in dimensions greater than one
Ali Mokhtari-Jazi, Matthew R. C. Fitzpatrick, Malcolm P. Kennett
Lieb-Robinson and related bounds set an upper limit on the rate of spreading of information in non-relativistic quantum systems. Experimentally, they have been observed in the spre…

Interacting quantum Hall states in a finite graphene flake and at finite temperature
Hank Chen, Matthew R. C. Fitzpatrick, Sujit Narayanan +2
The integer quantum Hall states at fillings and in monolayer graphene have drawn much attention as they are generated by electron-electron interactions. Here we ex…
