Extended edge modes and disorder preservation of a symmetry-protected topological phase out of equilibrium
Thomas L. M. Lane, Miklós Horváth, Kristian Patrick
The time evolution of topological systems is an active area of interest due to their expected applications in fault-tolerant quantum computing. Here, we analyze the dynamics of a n…
Enhanced localization in the prethermal regime of continuously measured many-body localized systems
Kristian Patrick, Qinghong Yang, Dong E. Liu
Many-body localized systems exhibit a unique characteristic of avoiding thermalization, primarily attributed to the presence of a local disorder potential in the Hamiltonian. In re…
Interaction distance in the extended XXZ model
Kristian Patrick, Vincent Caudrelier, Zlatko Papic +1
We employ the interaction distance to characterise the physics of a one-dimensional extended XXZ spin model, whose phase diagram consists of both integrable and non-integrable regi…
Efficiency of free auxiliary models in describing interacting fermions: from the Kohn-Sham model to the optimal entanglement model
Kristian Patrick, Marcela Herrera, Jake Southall +2
Density functional theory maps an interacting Hamiltonian onto the Kohn-Sham Hamiltonian, an explicitly free model with identical local fermion densities. Using the interaction dis…
Topological Quantum Liquids with Long-Range Couplings
Kristian Patrick, Titus Neupert, Jiannis K. Pachos
Very few topological systems with long-range couplings have been considered so far due to our lack of analytic approaches. Here we extend the Kitaev chain, a 1D quantum liquid, to…
