Magnetism and d-wave superconductivity on the half-filled square lattice with frustration
Andriy H. Nevidomskyy, Christian Scheiber, David Senechal +1
The role of frustration and interaction strength on the half-filled Hubbard model is studied on the square lattice with nearest and next-nearest neighbour hoppings t and t' using t…
Boundary of central tiles associated with Pisot beta-numeration and purely periodic expansions
S. Akiyama, G. Barat, V. Berthe +1
This paper studies tilings related to the beta-transformation when beta is a Pisot number (that is not supposed to be a unit). Then it applies the obtained results to study the set…
Recurrence for branching Markov chains
Sebastian Müller
The question of recurrence and transience of branching Markov chains is more subtle than for ordinary Markov chains; they can be classified in transience, weak recurrence, and stro…
On the reliability of linear band structure methods
G. Kontrym-Sznajd, M. Samsel-Czekala, G. E. Grechnev +1
We discuss an efficiency of various band structure algorithms in determining the Fermi surface (FS) of the paramagnetic ErGa3. The linear muffin-tin orbital (LMTO) in the atomic sp…
Compatible Geometric Matchings
Oswin Aichholzer, Sergey Bereg, Adrian Dumitrescu +10
This paper studies non-crossing geometric perfect matchings. Two such perfect matchings are \emph{compatible} if they have the same vertex set and their union is also non-crossing.…
Rate of Escape on the Lamplighter Tree
Lorenz Gilch
Suppose we are given a homogeneous tree of degree , where at each vertex sits a lamp, which can be switched on or off. This structure can be described by t…
