Dear group members,
Dori and I are rearranging furniture at home and will not need this couch-bed anymore.
It cost us originally 500 back in the bay area circa 2005. We used to have it in our living room when I was a postdoc. It is well preserved and has great storage drawers.
It is *free* to the first group member that agrees to come to my house (Cambrigeport) and take it away before next Saturday when we have other furniture come in. It is great as a guest bed!
I will send another picture of it in the next message.
Again, first come, first-serve.

Title: A Computational Engineer Combusts
Abstract: Large-scale production of very heavy oil is gaining momentum. Unfortunately, production of such reservoirs typically leads to large environmental impacts. One promising technique that may mitigate these impacts is in-situ combustion (ISC). In this process, (enriched) air is injected into the reservoir. After ignition a combustion front develops in situ that burns a small percentage of the oil in place and slowly moves through the reservoir producing steam along the way. The steam moves ahead of the front, heats up the oil, makes it runnier and hence easier to produce. A side benefit of this process is that the heat thus generated often cracks the oil into heavy, undesirable components that stay behind in the reservoir and lighter, more valuable components that can be brought up to the surface. In the last few years, my colleagues and I plunged into heavy oil recovery to see if computational mathematics could make a difference in pushing this process over less environmentally friendly processes in the industry. ISC processes are notoriously hard to predict. We developed a workflow involving laboratory experiments, various simulation tools and upscaling methods that increases the confidence of the oil reservoir engineer in ISC. We hope that this will lead to a wider acceptance and use of this technique.
Bio: Margot Gerritsen is a professor in the Department of Energy Resources Engineering at Stanford and director of the Institute for Computational and Mathematical Engineering (icme.stanford.edu<http://icme.stanford.edu/>). Her work is about understanding and simulating complicated fluid flow problems. Gerritsen's research focuses on the design of highly accurate and efficient parallel computational methods to predict the performance of enhanced oil recovery methods, with particular attention to gas injection and in-situ combustion processes. These recovery methods are extremely challenging to simulate because of the very strong nonlinearities in the governing equations. Outside petroleum engineering, she is active in coastal ocean simulation with colleagues from the Department of Civil and Environmental Engineering, yacht research and pterosaur flight mechanics with colleagues from the Department of Mechanical and Aeronautical Engineering, and the design of search algorithms in collaboration with the Library of Congress and colleagues from the Institute of Computational and Mathematical Engineering.

HQOC/ITAMP Joint Quantum Sciences Seminar
Wednesday, October 31st * 4:00 PM * Jefferson 250
Guest Presenter: Dr. Alexey Rubtsov, Moscow State University
"Continuous-time Quantum Monte Carlo: at the heart of in silico
modeling of correlated systems"
A description of strongly correlated quantum ensembles remains a major
challenge for physicists. In particular, electron correlations in solids
are responsible for the magnetism, high-Tc superconductivity, remarkable
optic and transport peculiarities, Kondo physics, etc. Contemporary
analysis of correlated solids employs an effective-medium paradigm, so
that the description of the entire solid is reduced to so-called
impurity model, describing a single atom (or small cluster of atoms)
placed in a bath. Although there is no general analytical solution for
impurity models, they can be treated numerically, using Continuous-time
Quantum Monte Carlo (CT-QMC) family of algorithms. These novel methods
are based on a stochastic path-integral calculation for quantum
statistical averages. The key ideas and state-of-art achievements of the
CT-QMC methods will be discussed; examples of specific calculations will
be given. We will also touch an application of CT-QMC to other systems,
in particular to the ultracold atom ensembles. Finally, current
unresolved issues in the field will be pointed out.

Speaker: Prof. Dörte Blume
Title: S-wave interacting fermions under anisotropic harmonic
confinement: Dimensional crossover of energetics and virial
coefficients
Abstract:
Few-body physics has played a prominent role in atomic, molecular,
chemical and nuclear physics since the early days of quantum
mechanics. It is now possible -- thanks to tremendous progress in
cooling, trapping, and manipulating ultracold samples -- to
experimentally study few-body phenomena in trapped atomic and
molecular systems with unprecedented control. This talk summarizes
recent studies of few-body phenomena in trapped fermionic gases. We
present accurate solutions of the Schrodinger equation for three
equal-mass fermions in two different spin states with zero-range
s-wave interactions and discuss the transition from
quasi-one-dimensional to strictly one-dimensional and
quasi-two-dimensional to strictly two-dimensional geometries. We
determine and interpret the eigenenergies of the system as a function
of the trap geometry and the strength of the s-wave interactions. The
eigenenergies are used to investigate the dependence of the second-
and third-order virial coefficients, which play an important role in
the virial expansion of the thermodynamic potential, on the geometry
of the trap. We show that the second- and third-order virial
coefficients for anisotropic confinement geometries are, for
experimentally relevant temperatures, very well approximated by those
for the spherically symmetric confinement for all s-wave scattering
lengths.

Afternoon Everyone!
Well now seems like as good a time as any to have a party! In Florida we
always follow up a nice hurricane with beer, food and good friends. As it
just so happens, after sandy blows on through (pun intended...) it should
be Halloween...ish!
So there will be a Halloween party at my house on Wednesday starting around
7-730pm. Everyone is invited! There will be food beer etc... though don't
let that make you afraid to bring something along if you so desire.
Otherwise just bring yourself and have some fun. Costumes not required but
you get brownie points if you come dressed up.
Let me know if you plan on coming so I can get a rough head count. I hope
to see you there!
My House is at
175 Summer St.
Somerville, MA 02143.
Its about a 5-10 min walk from the Porter T station.
Kind Regards,
Jon
Hi all,
RLE has a bike helmet that was left behind after the Excitonics seminar. Please let me know if it's yours.
Thanks,

Hey Cath,
Just an FYI, but apparently after the Excitonics Seminar a bike helmet was found in the conference room - in case any of your guys (gender neutral usage) is missing theirs.

Hi Everyone,
Sorry for the delay on this announcement but David Temple will be
giving group meeting today at the new time - 2:30 and due to an
important DARPA meeting that Prof. Shakhnovich has today, the meeting
will be in Naito 030 (Zhuang conference room). David's abstract is
included below!
Title: Disordered Polymer Systems
Abstract: I'll begin with a brief introduction to the statistical
physics of polymers and polymer field theory. Next, some recent
experiments and simulations of self assembled diblock copolymer melts
on imperfectly patterned (disordered) substrates will be presented.
I'll show how a simple analytical model can be used to understand the
different phases of the copolymer melts found in simulations and
experiments. Lastly, I'll discuss how the adsorption of a polymer on a
disordered template can be mapped onto the problem of Anderson
localization of electrons in disordered solids.
