Dvořák lectures

Vladimír Dvořák

Vladimír Dvořák (1934–2007)

Solid state physicist, the most prominent Czech scientist in the theory of ferroelectricity and structural phase transitions, for the whole productive life affiliated with the Institute of Physics, its director in 1993-2001, member of the Learned Society since 1995. The main protagonist of the revolutionary reforms in the Institute of Physics after 1989. To commemorate his work and personality, the Institute of Physics decided to organize an annual festive Dvořák lecture, given by prominent internationally renowned scientists in the field related to the research pursued at the Institute of Physics.

4: Graphene Ten Years Later

Wed, 06/06/2012 - 15:00 - 16:30

Prof. Allan H. MacDonald (University of Texas at Austin, USA)

Graphene is an atomically two-dimensional material which was first isolated for electronic property studies by Novoselov, Geim and collaborators from the University of Manchester about ten years ago. It is a gapless semiconductor formed entirely from carbon atoms and can be viewed as a giant aromatic molecule. Graphene’s honeycomb lattice structure is bipartite; atoms on one sublattice have three nearest neighbors all on the other sublattice.

3: Superfluid Helium-3: From very low Temperatures to the Big Bang

Wed, 08/06/2011 - 15:00 - 17:00

Prof. Dieter Vollhardt (University of Augsburg, Germany)

Since their discovery in 1971 the superfluid phases of Helium-3 have proved to be the ideal testing ground for many fundamental concepts of modern physics.

2: Quantum Information and the Foundations of Quantum Mechanics

Wed, 23/06/2010 - 15:00 - 17:00

Prof. Anton Zeilinger (University of Vienna, Austria)

Research on the foundations of quantum mechanics has given rise to the field of quantum information science. It should be stressed that this research beginning around the 1970s was not motivated by search for applications but rather by pure fundamental curiosity. Today, quantum computation, quantum teleportation, quantum communication, or quantum cryptography are novel concepts in information technology with no classical parallel.

1: Thermodynamic Approach to Nano-Inhomogeneous Ferroelectrics

Wed, 10/06/2009 - 15:00 - 18:00

prof. Yoshihiro Ishibashi (Nagoya University, Japan)

Collaboration with Vladimir Dvorak started when he stayed in Nagoya for three months in 1975, and lasted until his final days. His visit to Nagoya gave me big stimuli and benefi ts. I could learn how to apply the group theory to phase transitions directly from him, and since then we could jointly make a certain contribution to the progress of the theory of ferroelectric phase transitions. Among our joint works, the most memorable one is the development of the theory of the incommensurate phase transitions, of which much was not known at that time.
