Casimir Physics 2014 registration is closed

From March 30 through April 4, 2014

Ecole de Physique des Houches, France

Casimir physics embraces fundamental topics ranging from the role of quantum vacuum in fundamental physics and cosmology, the static and dynamic properties of the quantum and classical Casimir effect, atom-surface interactions in the physics of ultracold and thermal (Rydberg) atoms and molecules, to non-equilibrium phenomena and van der Waals forces in biological systems. It has also large overlap with condensed and soft matter, nanophysics, statistical physics and physical chemistry. In the last decade the Casimir physics community has brought together physicists from quantum field theory, quantum optics, atomic and molecular physics, soft matter, classical and quantum fluids, and nanophysics providing relevant theoretical and experimental contributions to this highly interdisciplinary topic.

This conference aims at bringing together main actors to present the state of the art and urgent questions of the different subfields to a young scientific public as well as to exchange methods and ideas, foster a cross-fertilization and establish interdisciplinary collaborations.

PAST EVENTS

Engineering the Casimir Force, Vilaflor, Tenerife, Spain, November 9-11, 2012
- Scientific Topics : The study of the Casimir force is an active area of theoretical physics and recent developments in experimental techniques are leading to new measurements of the Casimir force and presenting new challenges for theorists in the domains of both the quantum Casimir effect and the critical Casimir effect. A number of fundamental questions about the Casimir force are becoming accessible experimentally, two of particular importance are (i) the nature of the statistical fluctuations of the Casimir force and (ii) the behaviour of the Casimir effect out off equilibrium, both its relaxation to its equilibrium value and its behaviour in non-equilibrium and driven systems. It is also clear that in many contexts the Casimir effect is far from being an ideal one, and a good understanding of the effects of disorder and non-ideal material properties on the Casimir effect may be necessary to interpret experiments but also be practically important in order to engineer the Casimir effect.

Workshop"Kelvin Probe Force Microscopy analysis of surface potentials and patch effects in Casimir force measurements" 28 - 29 June 2012, University of Groningen, The Netherlands.
- The importance of measuring the electrostatic force is widely recognized in the Casimir community. It is now timely to organize a dedicated workshop to discuss this interface which is so important in the comparison with theory of the thermal Casimir force. The workshop will gather specialists coming from different domains, with the aim of exchanging information on the problems of interest at this interface as well as means of solving these problems. With Kelvin Probe force Microscopy (KPFM), the work function of surfaces can be characterized at nanoscales. The work function relates to many surface phenomena, including reconstruction of surfaces, doping and band-bending of semiconductors, charge trapping in dielectrics etc.. The map of the work function produced by KPFM gives information about the composition and electronic state of the local structures on the surface of a solid. It allows one addressing the challenge of patch characterization of real surfaces which also show roughness.
- Program of workshop : KPFM-Casimir workshop

Casimir School-Workshop 2012 (March 5-16, 2012) : It will be organized at the Lorentz Center of Leiden University (The Netherlands). The combined school-workshop aimed to explore developments on a global scale in the Casimir field as an education and research forum in Casimir physics. The school covered the basics in depth, general formalism, experiments and moving into the more advanced technical aspects, with a clear overview of the state of the art in the field. For this purpose we gave able time for young researchers and advanced researchers to interact in class and get acquainted with each other and initiate interactions and further collaborations (starting from the school and further focused by the workshop. Subsequently, therefore, the school will be followed by a workshop with the aim to further connect people doing current advanced work in the field of surface force measurements and micro/nano technologies with those who work on current problems of quantum field theory derived forces and to expand their understanding of these forces in common problems from nicro/nano technologies to gravity and laboratory cosmology :

●Casimir school : Based partly on the CASIMIR network program, the list of topics for the school were grouped into the following three major topics : i) Casimir effect : measurement and theory, ii) Challenges in vacuum properties, iii) Casimir interfaces

●Casimir workshop : The workshop focused on current advanced Casimir research and common topics : Progress in Casimir forces for complex geometries - novel topologies, Measurements and calculations of Casimir forces for new materials – MEMS/NEMS, Electrostatics in force measurement : patch effects and contact potentials, Lateral and repulsive Casimir forces-MEMS/NEMS, Measurements and manifestations of the thermal Casimir forces, Casimir-Polder interactions and thermal effects, Vacuum energy in quantum field theory and cosmology.

The school-workshop was open to participation by the Dutch and international research community via registration at the website of the school-workshop.

Tenth Conference QUANTUM FIELD THEORY UNDER THE INFLUENCE OF EXTERNAL CONDITIONS QFEXT11 : QFEXT11 was a continuation of a series of workshops of the same title held at the University of Leipzig in 1989, 1992, 1995, 1998, 2001, 2007, at the University of Oklahoma in 2003,2009, and at the University of Barcelona in 2005. Started with the intention of bringing about an East-West scientific dialog, QFEXT developed into one of the most prominent meetings in the field of the Casimir effect, vacuum energy, and related questions in several areas, ranging from quantum field theory and cosmology to atomic, subnuclear, and experimental physics. Typically mathematical questions related to spectral geometry are represented as well. These meetings have created a unique atmosphere where theoreticians, mathematicians and experimentalists are brought together for a week, where talks by colleagues that they might rarely hear otherwise often spark lively debate and result in numerous collaborations. QFEXT11 also celebrated the 75th anniversary of the seminal paper ’Consequences of the Dirac Theory of the Positron’, by W. Heisenberg and H. Euler (Zeitschr. Phys. 98, 714-732, 1936), which played an important part in establishing the study of quantum fields in classical background fields. We plan to include a special session devoted to Heisenberg-Euler effective Lagrangians and their impact in modern physics.

Dynamical Casimir effect : That was a 3 day workshop to organized in Padova 6-8 June 2011. The last 10 years, the interest to various dissipative effects in quantum vacuum, especially to the creation of quanta due to the motion of boundaries or changes of their properties, has increased significantly, both from the theoretical and experimental points of view. The workshop will gather most of the people that are involved in such physics, opening a discussion between theorists and experimentalists to evaluate the actual status of the research in this field and to look together for possible solutions of the emerging problems.

Casimir forces : effects of clusters and molecules close to and on surfaces : 2.5 day workshop in 11-13 May 2011. In this topical workshop theory and experiment worked together to tackle two very well-focused questions : 1. How do Casimir forces influence molecular beams close to real-world materials in real-world nanofabricated geometries ? 2. How can Casimir forces between two surfaces be modified by the deposition of size-selected nanoclusters of various types and shapes ?

Observability and theoretical grounding of thermal Casimir forces : Thermal issues in connection with the Casimir effect have been under study for actually several years, and this meeting contributed to further understanding of the effect. This was a topical meeting organized by Prof. I. Brevik for two days in 26- 27 January 2011 at the Department of Energy and Process Engineering together with the Institute of Physics of the Norwegian University of Science and Technology (NTNU). The talks of the meeting can be found here
