School & Workshop on Advanced Aspects of QFT

01. Overview

The c-Theorem at 40

Organized at the Instituto Balseiro / Centro Atómico Bariloche, in the Andean foothills of Patagonia, this event marks four decades since the formulation of the c-theorem.

The meeting aims to bring together leading researchers and students to discuss foundational and modern methods in quantum field theory. Topics will include structural aspects of QFT, renormalization group flows, irreversibility, and developments in high-energy theory.

The format combines lectures for advanced students and researchers, with research oriented talks and informal discussions.

The Instituto Balseiro hosts active research groups at the Centro Atómico Bariloche:

Particles & Fields Condensed Matter Theory Low Temperatures Statistical Physics Magnetism Medical Physics All Research Areas

      The emphasis is on ideas and methods that have shaped our understanding of quantum field theory.
    

04. Visitor Guide

Bariloche for Visiting Scientists

San Carlos de Bariloche sits in the heart of Argentine Patagonia, on the shores of Nahuel Huapi Lake and surrounded by the Andes. It is a beautiful, small city well accustomed to hosting international visitors. Here is practical advice for scientists traveling from abroad.

Getting Here

Bariloche's airport (BRC, Teniente Luis Candelaria) has daily flights from Buenos Aires, both from Aeroparque (AEP) and Ezeiza (EZE). The flight takes about two hours. Aerolíneas Argentinas, FlyBondi, and JetSMART operate these routes. International visitors typically connect through Buenos Aires.

Book domestic flights early — May is off-season but seats can fill up
EZE to AEP transfer (if connecting): Tienda León shuttle or taxi (~45 min)
BRC airport to city center: taxis and transfer services (~15 min)

Visa & Entry Requirements

Most nationalities (EU, US, Canada, UK, Japan, Australia, Latin America) do not need a visa for stays under 90 days. Check the Argentine Migration website for your nationality. We provide invitation letters upon request.

Bring your passport (valid for at least 6 months)
US citizens: check for reciprocity fee requirements
Keep a printed copy of your invitation letter

Getting Around

The Instituto Balseiro is at km 9.5 along Avenida Bustillo, the scenic road along the lake. Public buses run frequently. You need a SUBE card (rechargeable transport card), available at kiosks downtown.

Bus lines 10 and 20 go along Av. Bustillo to the Institute
Taxis and remises (pre-booked cars) are reliable and affordable
Ride-hailing apps: Cabify, DiDi, and Uber all operate in Bariloche
Downtown to IB: ~20 min by car, ~35 min by bus

Where to Stay

May is autumn and low season, so hotel prices are considerably lower than in ski season. We recommend staying along Av. Bustillo (km 1–10) for easy access to the Institute, or in the city center for more restaurants and services.

Budget-friendly hostels and cabañas in the km 1–5 range
Limited on-campus housing may be available for students (TBA)
The organizers can provide a list of recommended accommodations

Money & Practical Tips

Argentina uses the peso (ARS). Exchange rates fluctuate — check current rates before traveling. Credit cards are widely accepted. ATMs dispense pesos but may have daily limits.

Bring US dollars or euros as backup
Notify your bank before traveling to avoid card blocks
Tipping: 10% in restaurants is customary
Power plugs: Type I (three-prong), 220V / 50Hz

Weather & Things to Do

Late May in Bariloche is late autumn. Expect daytime temperatures of 5–12°C (40–54°F) and cold nights near 0°C. Rain and occasional snow are possible. Bring warm layers and a waterproof jacket.

Stunning scenery: lakes, coihue forests, snow-capped Andes peaks
Famous artisanal chocolate — Calle Mitre has many chocolate shops
Excursions: Circuito Chico, Cerro Campanario, Colonia Suiza
Excellent local craft beer scene along the lakefront
