294. The leptonic Higgs as a messenger of dark matter
This is a guest post by Piyush Kumar from U. of California, Berkeley. Dmitry. I would like to thank Dmitry for inviting me to post a guest blog on my recent paper “The leptonic Higgs as a messenger of dark matter” with Lawrence Hall and Hock-seng Goh on Dark Matter (DM). The story begins with [...]
293. Power counting semi-classical inflation models and Higgs-Inflation
This is a guest post by Michael Trott from Perimeter Institute. Dmitry. Thanks Dmitry for offering me the chance to explain the results of a recent paper (arXiv:0902.4465) by Cliff Burgess, Hyun Min Lee and myself. In this paper, we developed a power counting formalism to study the (often unspoken) limits of validity of various [...]
292. Universal properties of the U(1) current at deconfined quantum critical points
This is a guest post by Flavio Nogueira from the U. of Berlin. Dmitry. Before I start talking my recent preprint [http://arxiv.org/abs/0902.0364], let me thank Dmitry for inviting me to write this contribution in his blog. I cannot talk about my preprint without first talking a little bit about the paper of Pawel Kovtun and [...]
291. Chiral symmetry breaking in soft wall AdS/QCD model
This is a guest post by Tom Kelley from the U. of Minnesota who works on AdS/QCD with Tony Gherghetta. Dmitry. I would like to thank Dmitry for inviting me to talk a little about chiral symmetry breaking in the soft-wall AdS/QCD model, a topic in my recent work “Chiral Symmetry Breaking in Soft-Wall AdS/QCD” [...]
290. Last two weeks of February on NEQNET
February (and long cold winter!) has finally come to the end, and, if by a chance, you were unable to visit us for the last two weeks, here is what the buzz was about at NEQNET: 1. String theory, field theory, quantum gravity 1.1. Hamiltonian formulation of tetrad gravity: three dimensional case, where Natalia Kiriushcheva [...]
289. Patterned structures from a binary mixture of particles
This is a guest blog post by Carlos Mendoza from Instituto de Investigaciones en Materiales, Universidad Nacional Autonoma de Mexico. Let me start by thanking Dmitry for the invitation to write a guest blog entry about my recent paper arXiv:0901.4153. This has been done in collaboration with Erasmo Batta and has been accepted for publication [...]
288. A Pyramid Scheme for particle physics
This is a guest post by Jean-Francois Fortin from Rutgers. Dmitry. First of all I would like to thank Dmitry for requesting a guest post of the recent paper “A Pyramid Scheme for Particle Physics” (arXiv:0901.3578) that I coauthored with Tom Banks. The paper discusses a model of dynamical supersymmetry (SUSY) breaking which is not [...]
287. Heavy quark thermalization in classical lattice gauge theory
We use real-time lattice simulations to investigate the momentum diffusion of heavy quarks, which is observed to be surprisingly rapid in heavy-ion experiments, and point out the possibility to measure the corresponding diffusion constant in ordinary lattice simulations.
286. Nambu-Goldstone dark matter
This is a guest post by Yu Nakayama from the University of California, Berkeley. Dmitry. First of all, I’d like thank Dmitry for giving me this opportunity to post a guest blog on our hottest paper about Nambu-Goldstone Dark Matter (arXiv:0902.2914). This is based on the collaboration with M. Ibe, H. Murayama, and T.T Yanagida. [...]
285. Dephasing and diffusion of quantum particles
This is a guest post by Ariel Amir from the Weizmann Institute of Science. Dmitry. I was kindly asked by Dmitry to describe a recent work, where diffusion emerges from the decoherence in a noisy environment. This work was done together with Y. Lahini (an experimentalist) and H. Perets (an astrophysicist), and can be found [...]
