Fooling with mathematicians

I am still working with stochastic processes and, as my readers know, I have proposed a new view of quantum mechanics assuming that at the square root of a Wiener process can be attached a meaning (see here and here). I was able to generate it through a numerical code. A square root of a [...]

Lucasian chair again

On 22 May, Professor Michael Green, the incumbent Lucasian Professor at Cambridge University, will be 67 and must retire. He succeeded Stephen Hawking that left this chair for the same reason on 2009. Well before Hawking’s retirement, Cambridge University issued an announcement asking for possible candidates and, after the selection ended, Professor Green come out [...]

Back to CUDA

It is about two years ago when I wrote my last post about CUDA technology by NVIDIA (see here). At that time I added two new graphic cards to my PC, being on the verge to reach 3 Tflops in single precision for lattice computations.  Indeed, I have had an unlucky turn of events and [...]

Where does mass come from?

After CERN’s updates (well recounted here, here and here) producing no real news but just some concern about possible Higgs cloning, I would like to discuss here some mathematical facts about what one should expect about mass generation and why we should not be happy with these results, now coming out on a quarterly basis. [...]

Fabiola Gianotti at Accademia dei Lincei

On November 7th last year, Fabiola Gianotti, spokesperson of ATLAS experiment at CERN and one of the discoverers of the Higgs-like boson, has been nominated fellow of the Accademia dei Lincei. This is one of the oldest and most prestigious scientific societies that held fellows like Galileo Galilei and Enrico Fermi. Today, he held a [...]

End of the year quote

“Truth alone will endure, all the rest will be swept away before the tide of time. I must continue to bear testimony to truth even if I am forsaken by all. Mine may today be a voice in the wilderness, but it will be heard when all other voices are silenced, if it is the [...]

Curiosity finds organics but where do they come from?

Yesterday, at the meeting of the American Geophysical Union in San Francisco, NASA announced first results from soil analysis performed by Curiosity. Indeed, initially there was an eager expectation about this announcement as some rumors leaked out and somebody told about historical results. Then, all this was teased by NASA but what they announced yesterday [...]

A first paper on square root of a Brownian motion and quantum mechanics gets published!

Following my series of posts on the link between the square root of a stochastic process and quantum mechanics (see here, here, here, here, here), that I proved to exist both theoretically and experimentally, I am pleased to let you know that the first paper of my collaboration with Alfonso Farina and Matteo Sedehi was [...]

Unbreakable

Today, at HCP2012, new results on Higgs boson search were made available by CMS and ATLAS. Of course, well aligned with preceding rumors, all in all these appear rather disappointing. Maybe, beyond the increasing agreement with Standard Model expectations, the most delusional result is that the particle announced on July 4th appears to be completely [...]

Kyoto, arXiv and all that

Today, Kyoto conference HCP2012 has started. There is already an important news from LHCb that proves for the first time the existence of the decay. They find close agreement with the Standard Model (see here). Another point scored by this model and waiting for new physics yet. You can find the program with all [...]

Breaking of a symmetry: A paper

I have uploaded a paper on arXiv (see here), following my preceding post,  where I show that supersymmetry has inside itself the seeds for the breaking. I consider a Wess-Zumino model without masses (chiral) and I prove that, at lower momenta, it boils down to a Nambu-Jona-Lasinio model so, breaking supersymmetry through a gap equation [...]

Breaking of a symmetry

This week-end has been somewhat longer in Italy due to November 1st holiday and I have had the opportunity to read a very fine book by Ian Aitchison: Supersymmetry in Particle Physics – An Elementary Introduction. This book gives a very clear introduction to SUSY with all the computations clearly stated and going into the [...]

Large-N gauge theories on the lattice

Today I have found on arXiv a very nice review about large-N gauge theories on the lattice (see here). The authors, Biagio Lucini and Marco Panero, are well-known experts on lattice gauge theories being this their main area of investigation. This review, to appear on Physics Report, gives a nice introduction to this approach to [...]

Quote of the day

“With four parameters I can fit an elephant, and with five I can make him wiggle his trunk.“ (Attributed to von Neumann by Enrico Fermi, as quoted by Freeman Dyson in “A meeting with Enrico Fermi” in Nature 427 (22 January 2004) p. 297) Filed under: Quote Tagged: Enrico Fermi, Freeman Dyson, John von Neumann

Nobel prize to Serge Haroche e David Wineland

This year Nobel prize went to quantum optics for experiments that could be useful on the road to quantum computation. The awarded are Serge Haroche of the College de France and David Wineland from NIST (US). They performed groundbreaking  studies working with cavities and ion traps on single atoms and photons. I have had the [...]

Enrico Fermi’s birthday

Today is Enrico Fermi‘s birthday. Fermi has been a real Prometheus moving mankind to the age of nuclear energy for civil aims. His contributions to our current understanding of physics are enormous and we know as one of the greatest Italian scientist making an extraordinary pair with Galileo Galilei. The prominence of Italians on physics [...]

Confinement revisited

Today it is appeared a definitive updated version of my paper on confinement (see here). I wrote this paper last year after a question put out to me by Owe Philipsen at Bari. The point is, given a decoupling solution for the gluon propagator in the Landau gauge, how does confinement come out? I would [...]

Warp drive at NASA

I am currently a twitter user. One of my followings is Jeri Ryan. She has been Seven of Nine in Star Trek Voyager saga. Yesterday, it comes out of the blue what I read in one of her twits: NASA is developing warp drive! Indeed, Jeri was pointing to  this link. This is a Gizmodo’s [...]

ATLAS and CMS papers published

Papers by ATLAS and CMS have appeared in Physics Letters B and can be freely downloaded. They report on the discovery of the Higgs-like particle on July 4th. CMS Collaboration (2012). Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC Physics Letters B DOI: 10.1016/j.physletb.2012.08.021 ATLAS [...]
