IARD 2020

The 12th Biennial Conference on Classical and Quantum Relativistic Dynamics of Particles and Fields

1 – 4 June 2020 Virtual Meeting Online

Welcome from the Chairs

Petr Jizba, Conference Chair

Martin Land, IARD President

We are pleased to welcome everyone to IARD 2020, the 12th biennial meeting of the International Association for Relativistic Dynamics.

The goal of these meetings is to bring together researchers from diverse fields whose interests involve relativistic dynamics, both classical and quantum. The conference program aims to present recent developments in general theoretical approaches in field theory, manifestly covariant approaches to classical mechanics, quantum theory, and statistical mechanics, general relativity, classical and quantum gravity, and to explore applications in such areas as high energy spectroscopy, quark-gluon plasmas, scattering and particle decay, cosmology, gravitational waves, and relativistic quantum information.

IARD 2020 has been divided into two stages:

In this virtual meeting, we have organized talks into sessions covering related topics. For each session, you will find a list of speakers, a link to their presentation, a short bio, links to associated references, and a forum for discussion of the papers. We will also facilitate video-conference sessions for those interested.

The physical meeting at Czech Technical University in Prague, as originally planned for June. We strongly encourage all participants in this Virtual Meeting to attend and present their work in the IARD 2020 Physical Meeting.

IARD 2020 marks the association's 22nd year of activity since its founding at the 1998 meeting.

Eleven previous meetings were held in Houston, Texas, Bar Ilan University in Tel Aviv, Israel, Howard University in Washington DC, Saas Fee, Switzerland, the University of Connecticut in Storrs, CT, Aristotle University in Thessaloniki, Greece,and Hualien, Taiwan, Galileo Galilei Institute for Theoretical Physics (GGI) in Florence, Italy, again at UConn, in Ljubljana, Slovenia, and in Mérida, Yucatán, Mexico.

Conference Overview

The IARD 2020 Virtual Meeting is envisioned as an online discussion of the research reports found in the Conference Program. Click on any talk to find the abstract, lecture slides, notes, recorded talks, and other material. A Zoom videoconference will be open during the meeting for these conversations (details for connection to be announced soon by email to participants only). Questions and comments can also be sent by email to or directly to author's by contact information found on the lecture page.

Sessions and times: Talks are assigned to virtual sessions, divided between North America and Europe/Asia according to the location of the speakers. Each presentation is allocated a time for focused discussion, and in a few specified cases, the talk will be given live over Zoom at that time.

The sessions are listed here in real-time chronological order. Session times (coordinate times) are referred to Boston Time (GMT-4:00) for North America or to London Time (GMT+1:00) for Europe/Asia.

On each day, between the last session in Europe/Asia and the first session in North America, there is time for a Virtual Coffee Break, for general conversation.

Conference Program

1 – 4 September 2020 Czech Technical University in Prague

The organizers invite and encourage all participants in this Virtual Meeting to attend and present their work in the IARD 2020 Physical Meeting to be held at Czech Technical University in Prague, as originally planned.


The registration fee is € 300 (EUR), which covers participation in the conference, the excursion, the conference banquet and publication of the proceedings.The fee may also be paid as $325 (USD).

Accompanying partners may participate in the excursion and the banquet for an additional fee of € 50 (EUR) which may be paid as $55 (USD).
