Convolutional Polar Codes
Andrew James Ferris, Christoph Hirche, David Poulin
Arikan's Polar codes attracted much attention as the first efficiently decodable and capacity achieving codes. Furthermore, Polar codes exhibit an exponentially decreasing block er…
Chiral oily streaks in a smectic-A liquid crystal
Ian R. Nemitz, Andrew J. Ferris, Emmanuelle Lacaze +1
The liquid crystal octylcyanobiphenyl (8CB) was doped with the chiral agent CB15 and spin-coated onto a substrate treated for planar alignment of the director, resulting in a film…
Resonator reset in circuit QED by optimal control for large open quantum systems
Samuel Boutin, Christian Kraglund Andersen, Jayameenakshi Venkatraman +2
We study an implementation of the open GRAPE (Gradient Ascent Pulse Engineering) algorithm well suited for large open quantum systems. While typical implementations of optimal cont…
An efficient perturbation theory of density matrix renormalization group
Emanuele Tirrito, Shi-Ju Ran, Andrew J. Ferris +2
Density matrix renormalization group (DMRG) is one of the most powerful numerical methods available for many-body systems. In this work, we develop a perturbation theory of DMRG (P…
Modified spin-wave theory and spin liquid behavior of cold bosons on an inhomogeneous triangular lattice
Alessio Celi, Tobias Grass, Andrew J. Ferris +5
Ultracold bosons in a triangular lattice are a promising candidate for observing quantum spin liquid behavior. Here we investigate, for such system, the role of a harmonic trap giv…
Unbiased Monte Carlo for the age of tensor networks
Andrew J. Ferris
A new unbiased Monte Carlo technique called Tensor Network Monte Carlo (TNMC) is introduced based on sampling all possible renormalizations (or course-grainings) of tensor networks…
