LIR Computational Physics Group

Lester Ingber


To facilitate collaboration with other researchers via the Internet, I can offer a common platform described on which I am Principal Investigator (PI) of a National Science Foundation ( Extreme Science and Engineering Discovery Environment (XSEDE) supercomputer-resource grant, based on ideas published in several papers. For more information about XSEDE see .

This grant is for use of these resources for applications of computational physics as used in the above references, based on some projects related to those I have worked on previously. Work performed under an initial grant spanning 20 Feb 2013 - 19 Aug 2014 passed peer review for a second research grant spanning 1 Jul 2014 - 30 Jun 2015. On 20 Nov 2014 a request to double the current resources passed another round of review and was granted. In June 2015 another Renewal Request passed peer review, extending this grant through June 2016.

Note that this is a platform that gives opportunities in research collaboration for volunteers. Depending on your contributions, your rewards may be learning, producing new algorithms, acknowledgments, co-authorship, personal references that may help your career, etc.

If you are interested in collaborating on my XSEDE project, below are the steps I have volunteers use.

In all correspondence that require adding information to the body of email, please provide links instead of attachments whenever possible. If you cannot share individual files from Google Drive, Skydrive, Dropbox, etc., there are plenty of other similar free services.

Basic Premise

A working premise is that highly synchronous mass neuronal firings, as measured by scalp EEG, provides a feedback loop to synaptic background activity via a [p + q A] mechanism on Ca2+ free ions from regenerative astrocyte-neuron tripartite production processes. Here, A is the magnetic vector potential due to minicolumnar electric currents in the brain that give rise to EEG during selective attention tasks; q is the charge, and p is the momentum, of a free Ca2+ ion. Calculations in both classical and quantum physics support this premise.

Fits of this model to large EEG datasets, processed to run on the world's largest supercomputers available through, using my Adaptive Simulated Annealing (ASA) C-code available at ,
is a key component of this project. Previous runs have consumed several CPU-years on these platforms.

Some Previous Papers

Some previous papers on the Statistical Mechanics of Neocortical Interactions (SMNI) are at .

Some current papers relevant to this project are:

L. Ingber, "Statistical mechanics of neocortical interactions: Large- scale EEG influences on molecular processes," Journal of Theoretical Biology (2016).

L. Ingber, "Calculating consciousness correlates at multiple scales of neocortical interactions," in Horizons in Neuroscience Research, edited by A. Costa and E. Villalba (Nova, Hauppauge, NY, 2015), p. 153-186. [ ISBN: 978-1-63482-632-7. Invited paper. ]

L. Ingber, M. Pappalepore, and R.R. Stesiak, "Electroencephalographic field influence on calcium momentum waves," Journal of Theoretical Biology 343, 138-153 (2014).

L. Ingber, "Columnar EEG magnetic influences on molecular development of short-term memory," in Short-Term Memory: New Research, edited by G. Kalivas and S.F. Petralia (Nova, Hauppauge, NY, 2012), p. 37-72. [ Invited Paper. ]

Some Current Sub-Projects

A current sub-project is developing a complex-number version of PATHTREE:
L. Ingber, C. Chen, R.P. Mondescu, D. Muzzall, and M. Renedo, "Probability tree algorithm for general diffusion processes," Physical Review E 64 (5), 056702-056707 (2001). .

PATHTREE can be used to develop the wave-function described in the previous SMNI papers, adding "shocks" to the [p + q A] Ca2+ wave packet, to investigate the duration of the wave-packet due to a Zeno/bang-bang effect. This is similar to the use of PATHTREE to include dividends on the underlying asset in financial options.

At the least, this will provide researchers in several disciplines with a new fast numerical C-coded algorithm to perform path integrals of complex-number systems using the standard GCC compiler. PATHTREE and PATHINT already have provided such algorithms for real-number systems in several projects detailed at .

Another sub-project is to implement the N-dimensional code in PATHINT into PATHTREE. Both PATHINT and PATHTREE have been used to develop financial options, as reported in several papers at .
These papers deal with discretization issues that have been addressed in several contexts, including nuclear physics as reported in several papers at .

Contact Me Via Email

Contact me with an email to [email protected] so we can discuss whether you and the project would benefit from your membership. If this is agreed upon, then continue to the next steps.

Set Up An Account On XSEDE

(1) Set up your own account on . Also, see to set up a Portal Account. This all is pretty straightforward. It will take a day or two until your registration is in the XSEDE system. Send me an email to [email protected] to tell me the user name and email address you used to register.

(2) When I see your registered name and email in XSEDE, I can add you as a user to this project on, which can take over a day for XSEDE to process. Currently we have accounts at different XSEDE sites. I will send you an email when this step is complete.

(3) I do due diligence on the activity in this group regularly. Within a past month, if you have not make any contact with me, or have not done any work on any of our xsede projects, I'll remove you from this xsede project. This will not affect your registration on and you still can benefit from that.

I have to do this to be able to monitor the progress of these projects, and to know who to depend on for future progress. If you find that you have been removed, and feel I made an error in doing so, please just contact me by sending an email to [email protected] so that I can consider putting you back into the project.
