5th International Workshop DICE2010: Space-Time-Matter – Current Issues in Quantum Mechanics and Beyond

These proceedings present the Invited Lectures and Contributed Papers of the Fifth International Workshop on Decoherence, Information, Complexity and Entropy – DICE 2010, held at Castello Pasquini, Castiglioncello (Tuscany), 13–17 September 2010. These proceedings are intended to document the stimulating exchange of ideas at this conference for both the interested public and the wider scientific community, as well as for the participants. The number of participants attending this series of meetings has been growing steadily, which reflects its increasing attraction. Our intention to bring together leading researchers, advanced students, and renowned scholars from various areas in order to stimulate new ideas and their exchange across the borders of specialization seems to bear fruit. In this way, the series of meetings has continued successfully from the beginning with DICE 2002 [1], followed by DICE 2004 [2], DICE 2006 [3], and DICE 2008 [4], uniting more than 100 participants representing almost 30 countries worldwide. It has been a great honour and inspiration to have Professor Luc Montagnier (Nobel Prize for Medicine 2008) from the World Foundation for AIDS Research and Prevention with us, who presented the lecture DNA waves and water (included in this volume). The discussions took place under the wider theme Space-Time-Matter – current issues in quantum mechanics and beyond in the very pleasant and inspiring atmosphere of Castello Pasquini, which – with its beautiful surroundings, overlooking the Tuscany coast – hosted the conference very successfully for the second time. The five-day program was grouped according to the following topics: Gravity and Quantum Mechanics Quantum Coherent Processes in Biology / Many-Body Systems From Quantum Foundations to Particle Physics The Deep Structure of Spacetime Quantum – Relativity – Cosmology A Public Roundtable Discussion formed an integral part of the program under the theme Sull' Onda Della Coerenza – le nuove frontiere della scienza moderna with the participation of E Del Giudice (INFN & Universita di Milano), L Fronzoni (Universita di Pisa) and G Vitiello (Universita di Salerno). By now forming a tradition, this evening event drew a large audience, who participated in lively discussions until late. The workshop was organized by L Diosi (Budapest), H-T Elze (Pisa, chair), L Fronzoni (Pisa), J Halliwell (London), E Prati (Milano) and G Vitiello (Salerno), with essential help from our conference seceretaries M Pesce-Rollins and L Baldini and from our students G Gambarotta and F Vallone, all from Pisa. Several institutions and sponsors supported the workshop; their representatives and, in particular, the citizens of Rosignano / Castiglioncello are deeply thanked for their generous help and kind hospitality: Comune di Rosignano – A Franchi (Sindaco di Rosignano), S Scarpellini (Segreteria sindaco), L Benini (Assessore ai lavori pubblici), M Pia (Assessore all' urbanistica). REA Rosignano Energia Ambiente s.p.a. – F Ghelardini (Presidente della REA), E Salvadori (Segreteria). Associazione Armunia – M Paganelli (Direttore), G Mannari (Programmazione). Special thanks go to G Mannari and her collaborators for their advice and great help in all the practical matters that had to be dealt with in order to run the meeting at Castello Pasquini smoothly. Funds made available by Universita di Pisa, by Domus Galilaeana (Pisa), Centro Interdisciplinare per lo Studio dei Sistemi Complessi – CISSC (Pisa), Dipartmento di Matematica e Informatica (Universita di Salerno), Instituto Italiano per gli Studi Filosofici – IISF (Napoli), and by the Hungarian Scientific Research Fund OTKA, are gratefully ackowledged. Last, but not least, special thanks are due to Laura Pesce (Vitrium Galleria, San Vincenzo) for the exposition for her artwork Dal io al cosmo at Castello Pasquini during the conference. The papers presented at the workshop and collected here have been edited by L Diosi, H-T Elze, L Fronzoni, J J Halliwell, E Prati, G Vitiello and J Yearsley. The proceedings essentially follow the order of presentation during the conference program, however, divided into Invited Lectures and Contributed Papers. (We regret that lectures by D Bouwmeester, G G Guerreschi, G C Ghirardi and C Kiefer could not be reproduced here, partly for copyright reasons.) In the name of all the participants, we would like to thank S Toms and G Douglas, and their collaborators at IOP Publishing (Bristol) for their friendly advice and most valuable and immediate help during the editing process and, especially, for their continuing efforts to make the Journal of Physics: Conference Series available to all.
