ActAPhysica   – a new journal in Physics


There are a few reasons for the foundation of a new journal in Physics. Physics is strongly developing – every month there appear thousands of papers on physics, there is an urgent need to publish them and provide them to the scientific community as quick as possible for the exchange and development of our knowledge.


Due to this enormous increase of physical production (there is a doubling of papers every 15 years) the publication time also enormously lengthens. Please image that hundreds years ago, in the year of 1905 – a miracle year of Einstein, papers have been published within 14 weeks (the first famous paper of Einstein has been submitted March 17, 1905 and has been published June 9, 1905; please remember that at that time Einstein was a completely unknown 26 year old young man). At present a normal time for the publication is a half of year, at least.


More important is that we feel that there is a scientific crisis in the modern solid-state physics. There is growing rapidly experimental data on many, many samples but their understanding is rather poor. There is a lack of the open discussion and one can find evidence of discrimination or even inquisition of theories based on the crystal-field theory. A widely-spread strong-correlation electron systems topic is a so loosely defined subject that, in fact, this part of physics seems not to deserve to be called an exact science any more. After a mixed valence topic in the sixties, heavy-fermion compounds in the eighties and after an unexpected discovery of the high-temperature superconductivity in 1986 at present this name covers all compounds with transition-metal atoms.


Despite thousands of papers on the heavy-fermion subject a problem of charge or neutral excitations has not been established yet. For the transition-metal compounds we point out the importance of the low-energy electronic structure with energy details below 1 meV and the importance of the local effects, in the atomic scale, in the description of the macroscopic properties of solids. In ActAPhysica we would like to contribute to a revitalization of the crystal-field ideas of Bethe, Van Vleck, Kramers, Tanabe, Sugano and many others on the occasion of 75-years of the discovery of the crystal-field theory. We do not separate Physics to an old and a new one. We think that Physics is only good or bad, less or more adequate to the physical reality. We take as very important experimental findings in Frank Steglich group of very well localized states in heavy-fermion metal compounds UPd2Al3 and YbRh2Si2 -such states have been expected in the crystal-field based theories but completely unexpected in very popular delocalized f electron ones. The same is with Mott insulators, say NiO. It is known to be insulator but band theories starting with its description as a metal are supported by last 70 years. 


We treat work in Physics ad an integral job searching for the scientific truth. It should be made in the friendly atmosphere with the acceptance of different scientific approaches. We understand different scientific opinions as a good sign of the scientific vitality of the given subject. We declare to follow standard scientific rules. In particular, we declare not to use the referee system for a scientific discrimination of anybody. In case of negative referee reports and insisting by author(s) to publish his/their paper, it will be published, shortened if necessary, together with relevant editorial remarks containing, if possible, referees’ objections. Care will be taken for husking of the scientific disagreement. 


We offer ActAPhysica to all physicists for research articles from all of the physics areas. We declare a short publication time – surely not longer than in the Einstein time.  Apart of the pure research articles we intend to have less scientific sections like History of Physics and Science, Varia and so on. We intend to follow somehow the most prestigious journals, where also less scientific parts can be found – but scientific articles will be marked with the RESEARCH ARTICLE note. We think that different advertisements will be useful for our readers as information on different conferences, scientific equipments, job offers and scientific comments. 

Please take our offer and find ActAPhysica as a good source of knowledge and a publication medium.
