The objective of this project is the theoretical and computational study of nanomaterials using frontier simulation methods. For this, we require computational systems that have connected processors in parallel with a fast network communication, besides that we generate a huge amount of data that needs to be analized in our workstations.

The objective of this project is to develop models that describe the movements of sets of groups of animals en complex environments, this with the end of understading the space-time structure of the contact networks that they form. This is of great interest to study the propagation of diseases (like Ebola) in primates. This is an interdisciplinary study, which involves international colaborations. We are developing code of great complexity to simulate as close to the reality the trajectories of the animals, taking into account the interaction of these with the resources. The models are being validated with field data already available some of them with millions of lines of data.

We are doing calculations of gas of electrons and eventually of processes of fields theory using Mathematica. This will be used in Montecarlo calculations to obtain efficient sections. To obtain resultad that assure us the convergence to low densities in the gas of electrons and, in the case of particles, to have fast retroalimentation to better model this processes.

We pretend to calculate the optical response of different semi-conductor systems that involve at least hundreds of atoms, like amorphes, clusters and surfaces. In the calculation of the optical properties is necessary to do numerical integration over a great number of points at the zone of Brillouin of crystaline systems, which can be done in parallel.

We study the dynamics of interconnected systems with auto-organizational properties. The type of systems studied are of biological nature such as neural networks and emergent computing, social dynamics and auto-organized criticality.

Nowadays, we study Hydrogen in extreme conditions, i.e. at great pressure and at very high temperatures. The objective is to known the thermodynamic states of the hydrogen, as much as the new properties that this element presents under such conditions. The research is made in colaboration abroad who, as us, have computer clusters for calculations.

Our work tries to characterize the cruce called BEC-BCS: a set of fermionic atoms at very low temperatures of the order of tens of nanokelvins, this one interacts with diverse intensities such that the natural minimal objects become from being practically isolated atoms to be Cooper pairs or molecules. In the Ollin cluster at our Institute we have done simulations of this effect using the variational Montecarlo technique in the real space and with this we have 580 interactive particles. We would like to remark that this superates in an order of magnitude the number of particles used by any other group to international scale.

I develop methods of first principles to calculate the atomic and molecular properties with a range of controlled exactitude or almost controlled, that hugs from the very exact calculations that incorporate all the corrections that the physics demands (relativists, radioactives, finite effect of the number, etc) to the calculation of spectral molecules relatively big where it is used the non-relativistic regimen and approximations ad-hoc. The final objective of the program is to have with a "knob" that selects different thresholds of aproximation, from the more primitive ones to the actual limits of exactitude. Internet 2 in an technological imperative that will allow us applications more and more demanding, in consonance with works developed at the most advaced places.

The research of hadronic matter in extreme conditions is made with colaborations with people form UNAM and from FSU (Florida State University). To understand what's inside the quarks and the interactions between them in extreme conditions will allow to predict the existence of new states relevant to the collision physics of heavy ions and astrophysics.
It is widely accepted that environments of high density at the center of star of neutrons constitute a place that is good for the formation of quark matter. The search in colliders of heavy ions is a good place to study the phenomenology of quarks in deconfined state, putting the detection of this exotic phase of matter in an observational place. Using numerical techniques we have done Montecarlo simulations with a model of exchangeability of quarks (string-flip), determining how the transition of matter of quarks with strange quarks happens, there, the effects of interaction remains important even at conditions of very high density. The response of the system to fields of color of heavy quarks like the J/psi, we study it, finding a great correlation of its properties with the transition to the deconfined state.
