Entanglement correction due to local interactions in many-body systems
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
The correction to the area law for the bipartite min-entanglement entropy of weakly and locally interacting fermions is calculated based on a perturbative extension of the flow equ…
Environmental effects in quantum annealing
Tobias Chasseur, Stefan Kehrein, Frank K. Wilhelm
For quantum annealing, as opposed to circuit based quantum computing, the solution to a computational problem is encoded in the ground state of a quantum system. Therefore its susc…
Exact description of the boundary theory of the Kitaev Toric Code with open boundary conditions
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
In this work we consider the Kitaev Toric Code with specific open boundary conditions. Such a physical system has a highly degenerate ground state determined by the degrees of free…
