Disorder-induced phases in the S=1 antiferromagnetic Heisenberg chain
Péter Lajkó, Enrico Carlon, Heiko Rieger +1
We use extensive density matrix renormalization group (DMRG) calculations to explore the phase diagram of the random S=1 antiferromagnetic Heisenberg chain with a power-law distrib…
On the Worst-case Performance of the Sum-of-Squares Algorithm for Bin Packing
Janos Csirik, David S. Johnson, Claire Kenyon
The Sum of Squares algorithm for bin packing was defined in [2] and studied in great detail in [1], where it was proved that its worst case performance ratio is at most 3. In this…
Bounded-Degree Graphs have Arbitrarily Large Geometric Thickness
Janos Barat, Jiri Matousek, David R. Wood
The geometric thickness of a graph G is the minimum integer k such that there is a straight line drawing of G with its edge set partitioned into k plane subgraphs. Eppstein [Separa…
Transit Photometry of the Core-Dominated Planet HD 149026b
David Charbonneau, Joshua N. Winn, David W. Latham +8
We report g, V, and r photometric time series of HD 149026 spanning predicted times of transit of the Saturn-mass planetary companion, which was recently discovered by Sato and col…
Quantum rings as electron spin beam splitters
Peter Foldi, Orsolya Kalman, Mihaly G. Benedict +1
Quantum interference and spin-orbit interaction in a one-dimensional mesoscopic semiconductor ring with one input and two output leads can act as a spin beam splitter. Different po…
Microwave emission from a crystal of molecular magnets -- The role of a resonant cavity
Mihaly G. Benedict, Peter Foldi, F. M. Peeters
We discuss the effects caused by a resonant cavity around a sample of a magnetic molecular crystal (such as Mn-Ac), when a time dependent external magnetic field is applie…
