Quantum Monte Carlo
and the CASINO program VIII
The eighth international summer school in the "Quantum Monte Carlo and the
CASINO program" series took place from Sunday 4th August to Sunday 11th
August 2013 and involved 25 students from 16 countries.
The purpose of the school was to provide the students with a thorough
working knowledge of the quantum Monte Carlo electronic structure method as
currently used in quantum chemistry and condensed matter physics and to show
them how to use the Cambridge CASINO QMC program for serious scientific
research. The participants spent around four hours each morning listening to
lectures on the quantum Monte Carlo method. This was followed by practical
examples classes with the CASINO software, and a programme of healthy
recreational activities such as mountain walking and cave exploration.
In the late afternoons various groups of students attacked and conquered Monte Matanna, the cylindrical rock tower of Monte Procinto, the wild Turrite di San Rocco canyon, the legendary Cave of Cascaltendine, the Cave of Fairies of Vallico Sotto, the natural rock arch of Monte Forato, the terrifying 'Cave That Screams', the mighty Orrido di Botri canyon, and a small hill near San Pelligrinetto with quite a nice view. Special mention should be made of Englishman Matthew Malcomson and Russian Yury Gladush, who spent the week showing off their tremendous athletic abilities and natural courage, by unnecessarily running up very steep mountains just because they could, and by free-climbing various suicidally dangerous slippy rock faces. Following his exploits in the annual "Vallico Sotto against the World" football match,
in which he wore only a pair of shorts and no shoes, Malcomson was nicknamed "La Bestia" - the Beast - by locals, and quite right too.
OK so we lost 12-11 on a Golden Goal after a hard fought match against their Junior team, but it's better than being absolutely caned as is more usual on these occasions. Both men also demonstrated their considerable musical abilities in a Rock'n'roll evening at the Vallico Sotto Star Club, along with Minh Tam Nguyen, Ludmila Szulakowska, Sofia Silva, Mr. Pablo López Ríos (who also managed a 40-minute drum solo during a traditional Vallico Sotto dance night down in the village) and others.
To check which students have been paying most attention during the lectures
and practical classes, we traditionally hold a tough examination on the final
The highest mark and the award of the prestigious title of "TTI QMC Summer
School Champion 2013", went to Pride of Poland Blazej Jaworowski from Wroclaw, for
which he was awarded the prize of a 19th century Gentleman's Telescope.
Following our first-ever seaside day trip to Lerici and Portovenere, his triumph was celebrated in the TTI church with fine Barolo-soaked cheese from Lucca and a quality speech from the victor which could have been given by Abraham Lincoln. After Booth shot him.
This year marked the promotion of 17-month-old Jamie Towler to our staff. We are somewhat unhappy to report that he
spent the week perambulating about the Institute, clad only in a nappy/diaper, stealing people's possessions from their rooms, chewing them, and attempting to throw them into the lavatory - before parading into the back of the church and making screeching noises during his father's lectures. It is to be hoped that - following a rigorous and intensive training program - he might be of considerably more use in future years.

"I just wanted to express my greatest thanks for this
wonderful QMC school which in my opinion is the best combination of
high-level science and great atmosphere ever. Thanks for all the efforts put
"I just wanted to say thanks very much again for this absolutely fantastic
week; the places as well as the people were delightful! I'm sorry I didn't
get to say bye to you or Sammy properly (traveling days are always a bit
hectic) but please tell Sammy and Saska that I really enjoyed their company
and it was so nice of your family to be so very welcoming."
"After safely arriving home I want to thank you (and all the people who
helped you) once more for organizing such a great school. I thoroughly
First of all, the organizational part was excellent with me not having to
think about any technical details at all during the school. Adding to this
the amazingly complete pre-school instructions, I must say that the
organizational part was really great.
The balance between learning activities, sightseeing and Italian dinners
(which were as substantial as long :) ) could hardly be better.
However, I would hardly survive more than a week of such regime, - and I can
only imagine how it was to you. Which makes me even more grateful. :)
So in conclusion, I say REALLY HUGE THANK YOU!!!
"I'd like to thank you very much for the great week in Vallico Sotto. It was both instructive and really enjoyable. I had a lot of fun and I couldn't dream of learning more. I am also glad to have met so many wonderful people!"
"Thanks again for organising the conference and summer school! As ever they
are by far the best workshop & summer school that one could ever hope to
