Dmitry Podolsky has got his PhD from Landau Institute for Theoretical Physics. He currently works as postdoc at Case Western Reserve University. He is also one of the editors of NEQNET.

50. Planck 2008: day 4

4th day of the Planck 2008 was devoted to unparticle physics (feat. Howard Georgi himself) and AdS/QCD.

49. Polyakov’s interview

Interview with Alexander Polyakov where he discusses how he came in science, met Lev Landau and many other interesting things from the history of modern field theory.

48. Planck 2008: day 3

The third day of Planck 2008 was devoted to experimental side of LHC, physics of hidden sectors, quirks and N=1 SQCD.

47. Planck 2008: First and second days

First and second days of the PLANCK 2008 conference: flavor physics, RS phenomenology, WMAP, bigravity, WIMPonium, black holes and number of species.

46. Leaving for Planck 2008

I am leaving for Planck 2008 conference, will be back on May 24. I hope I will have an internet connection there to be able to blog (if so, I plan to blog a bit about the conference itself ) If I will not, apperently, I’ll remain silent for a week. Cheers to you, my [...]

45. Quantization of cosmological perturbations. Mukhanov-Sasaki variable (Inflationary perturbations 5)

I introduce Mukhanov-Sasaki variable, show how to quantize inflationary perturbations and again calculate the power spectrum of primordial perturbations – by QFT this time.

44. Cosmological perturbations in the presence of scalar field (Inflationary perturbations 5)

I discuss cosmological perturbation theory in the Universe where the dominant component of matter is a scalar field. It is show that spectrum of inflationary perturbations is nearly flat.

43. Schwinger-Keldysh: Martin-Siggia-Rose diagrammatics (non-equilibrium diagrammatic methods 2)

I start to discuss Martin-Siggia-Rose diagrammatic methods and transition from Fokker-Planck equation back to quasiclassical Schwinger-Keldysh action.

42. Recalling a couple of facts about 2D and 3D Ising models

I discuss free fermion representation for the 2D Ising model and mention how string theory can be related to the critica behavior of the 3D Ising model.

41. Peter Woit: What will you do if string theory is wrong?

Well, let us figure out in which sense it could be wrong
