Vladimír Dvořák

Vladimír Dvořák (1934–2007)

Významný český vědec, který pracoval ve fyzice pevných látek. Zabýval se teorií feroelektrických látek a strukturálních fázových přechodů. Celý svůj produktivní život spojil s Fyzikálním ústavem. Byl jeho ředitelem v letech 1993-2001. Členem Učené společnosti byl od r. 1995. Byl protagonistou revolučních reforem ve Fyzikálním ústavu po roce 1989. K uctění této osobnosti a jeho práce organizuje Fyzikální ústav každoročně slavnostní Dvořákovu přednášku, přednesenou mezinárodně uznávanou autoritou v některém z oborů výzkumu Fyzikálního ústavu.

The emergence of the “Internet of Things” and the explosion of Artificial Intelligence/Machine Learning applications are likely to push up significantly the market for microelectronics. The related energy consumption could increase by 20–25%. Thus, looking for a new generation of ultralow power memories and switches is an area of significant current research. Perovskite oxides exhibit a rich spectrum of functional responses, including magnetism, ferroelectricity,...

The 10th Dvořák Lecture

An important challenge in many applications, ranging from biosensors to drug delivery, is the prevention of nonspecific protein adsorption on surfaces. To address this challenge, our goals are twofold. First, we strive to provide a fundamental understanding of nonfouling mechanisms at the molecular level using an integrated experimental and simulation approach.

Prof. Paul Lecoq (CERN, Geneva, Switzerland)

The 9th Dvořák Lecture

The future generation of radiation detectors is more and more demanding on timing performance for a wide range of applications, such as time of flight (TOF) techniques for PET cameras in medical imaging and particle identification in nuclear physics and high energy physics detectors, precise event time tagging in high luminosity accelerators and a number of photonic applications based on single photon detection.

Prof. Marco Cavaglià (Department of Physics and Astronomy, University of Mississippi, USA)

The 8th Dvořák Lecture

In 1916 Albert Einstein demonstrated that the theory of General Relativity allows for wave-like, space time perturbations propagating with the speed of light. Two years later, he calculated his famous quadrupole formula, describing how these “gravitational” waves can be generated. However, due to the extreme weakness of gravity, detecting gravitational waves seemed an impossible task. They even became a matter of controversy with Einstein himself becoming convinced they did not exist.

The 7th Dvořák Lecture

Theory predicts that with an ultra-short and extremely bright coherent X-ray pulse, a single diffraction pattern may be recorded from a large macromolecule, a virus, or a cell before the sample explodes and turns into a plasma. The over-sampled diffraction pattern permits phase retrieval and hence structure determination. X-ray lasers capable to deliver ultra bright and very short X-ray pulses for such experiments have recently started operations.

Orazio Svelto (Politecnico di Milano, Italy)

The 6th Dvořák Lecture

From the race to make the first laser to early developments in laser science, a description will be made of the most important achievements. Likewise, the birth of nonlinear optics and the ad- vent of ultrafast laser science will also be considered. In any case, a very coarse review of some of most important achievements will be presented, with the addition of a few anecdotes and cu- riosities as derived by the personal reminiscence of the author.

Peter Jenni (University of Freiburg, Germany and CERN, Geneva, Switzerland)

The 5th Dvořák Lecture

Since three years the experiments at the Large Hadron Collider (LHC), in particular ATLAS, investigate particle physics at the highest collision energies ever achieved in a laboratory. Following a rich harvest of results for Standard Model (SM) Physics came in 2012 the first spectacular discovery of a new, heavy particle, most likely the long-awaited Higgs boson.

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

The 4th Dvořák Lecture

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.

The 3rd Dvořák Lecture

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. Phenomena such as Cooper pairing, macroscopic quantum coherence, spontaneous breaking of high symmetries, and the formation of exotic topological defects are not only an important enrichment of the physics of condensed matter,

Prof. Anton Zeilinger (University of Vienna, Austria)

The 2nd Dvořák Lecture

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.
