Mass distributions of fission fragments arising from the slow quasifission (SQF) process,
derived by comparing the measured data with theory for several reactions, show distinct …

In this work we describe how to systematically implement a full graph decomposition to set
up a linked-cluster expansion for the topological phase of Kitaev's toric code in a field. This …

We demonstrate that two toric code layers on the square lattice coupled by an Ising
interaction display two distinct phases with intrinsic topological order. The second-order …

We study the entanglement structure and the topological edge states of the ground state of
the spin-1/2 XXZ model with bond alternation. We employ parity-density matrix …

We study the robustness of 3D intrinsic topogical order under external perturbations by
investigating the paradigmatic microscopic model, the 3D toric code in an external magnetic …

Topologically ordered quantum phases are robust in the sense that perturbations in the
Hamiltonian of the system will not change the topological nature of the ground-state wave …

Topologically ordered phases have robust degenerate ground states against the local
perturbations, providing a promising platform for fault-tolerant quantum computation. Despite …

In non-relativistic quantum theories the Lieb-Robinson bound defines an effective light cone
with exponentially small tails outside of it. In this work we use it to derive a bound for the time …

In this work, we provide an analytical proof of the robustness of a form of topological
entanglement under a model of random local perturbations. We define the notion of …

The information content of the two-particle one-and two-dimensional Calogero model is
studied by using the von Neumann and Rényi entropies. The one-dimensional model is …
