Improved results for a memory allocation problem
Leah Epstein, Rob van Stee
We consider a memory allocation problem that can be modeled as a version of bin packing where items may be split, but each bin may contain at most two (parts of) items. A 3/2-appro…
Collective Field Formulation of the Multispecies Calogero Model and its Duality Symmetries
V. Bardek, J. Feinberg, S. Meljanac
We study the collective field formulation of a restricted form of the multispecies Calogero model, in which the three-body interactions are set to zero. We show that the resulting…
Local bulk operators in AdS/CFT: A holographic description of the black hole interior
Alex Hamilton, Daniel Kabat, Gilad Lifschytz +1
To gain insight into how bulk locality emerges from the holographic conformal field theory, we reformulate the bulk to boundary map in as local a way as possible. In previous work,…
Magnetothermal transport in the spin-1/2 chains of copper pyrazine dinitrate
A. V. Sologubenko, K. Berggold, T. Lorenz +4
We present experiments on the thermal transport in the spin-1/2 chain compound copper pyrazine dinitrate Cu(C_4 H_4 N_2)(NO_3)_2. The heat conductivity shows a surprisingly strong…
On double Hurwitz numbers in genus 0
Sergei Shadrin, Michael Shapiro, Alek Vainshtein
We study double Hurwitz numbers in genus zero counting the number of covers $\CP^1\to\CP^1$ with two branching points with a given branching behavior. By the recent result due to G…
Restricted Motzkin permutations, Motzkin paths, continued fractions, and Chebyshev polynomials
Sergi Elizalde, Toufik Mansour
We say that a permutation is a Motzkin permutation if it avoids 132 and there do not exist such that . We study the distribution of several statistics in…
