Fermionic and bosonic Laughlin state on thick cylinders
Partial Abstract: We investigate a many-body wave function for particles on a cylinder known as Laughlin's function. It is the power of a Vandermonde determinant times a Gaussian. Our main result is: in a many-particle limit, at fixed radius, all correlation functions have a unique limit, and the limit state has a non-trivial period in the axial direction.
Extended states for polyharmonic operators with quasi-periodic potentials in dimension two
Yulia Karpeshina and Roman Shterenberg
This paper proves that the absolutely continuous spectrum of H contains a semiaxis and there is a family of generalized eigenfunctions at every point of this semiaxis with specific properties. These properties demonstrate that the eigenfunctions are close to plane waves ei ‹k, x› at the high energy region and the isoenergetic curves in the space of momenta k corresponding to these eigenfunctions have a form of slightly distorted holes.
Reconstructing acoustic obstacles by planar and cylindrical waves
Jingzhi Li, Hongyu Liu, Hongpeng Sun, and Jun Zou
A linear sampling-type method is developed for the inverse obstacle scattering problem using near-fields through the DtN or NtD maps with planar or cylindrical incident waves. This method is primarily for qualitative reconstructions and has been mathematically justified. Numerical experiments are presented to demonstrate the effectiveness of the method and show that some fine aspects of the underlying obstacles may be captured.
Geometric descriptions of entangled states by auxiliary varieties
Frédéric Holweck, Jean-Gabriel Luque, and Jean-Yves Thibon
An alternative approach to the geometric descriptions of entanglement is presented. Auxiliary varieties such as join, tangent, and secant are used instead of a description by dual varieties. The introduction of these varieties brought a more precise description of the singular locus of the dual varieties as the authors were able to interpret the singular components of X*as dual varieties of the stratification by join and tangential varieties. This approach could bring interesting perspectives for the geometric description of entanglement in QIT.
Third order integrability conditions for homogeneous potentials of degree −1
Thierry Combot and Christoph Koutschan
The non-integrability proofs of meromorphic homogeneous potentials of degree −1 in the plane is discussed and in particular for nongeneric cases. The general holonomic approach presented could work for all problems about integrability of homogeneous potentials since it allows for the computation of various higher integrability conditions of fixed order.
On the joint distribution of the maximum and its position of the Airy2 process minus a parabola
Jinho Baik, Karl Liechty, and Grégory Schehr
The scaling limit of the end-point of the directed polymer in a random medium is described by the maximal point of the Airy2 process minus a parabola and has been proven for a few cases. Two different formulas for the joint distribution of the location and height of this maximal point were obtained and this article gives a direct proof that these two formulas are the same.

CrossMark Implemented on AIP journals
AIP Publishing is dedicated to scientific accuracy and integrity and as a result has implemented CrossMark on its publications. As of December 2012, a CrossMark logo will appear on an HTML page or PDF file indicating that the publisher is maintaining the published document through any updates, corrections, enhancements, retractions, and other such changes. Clicking the CrossMark logo reveals status information about the document and tells readers whether they are accessing the most recent and reliable version or not. A link to any updated version will be included. You can learn more about CrossMark from the CrossRef website.
The American Institute of Physics congratulates this year's Nobel Laureates in Physics, Serge Haroche and David J. Wineland “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems."
