Aims and Scope

The scope of EPJB spans the fields of Condensed Matter, Quantum Materials and Low-Dimensional Systems, as well as Statistical Physics, Nonlinear Dynamics and Complex Systems. A non-exhaustive list of subtopics in each field is given below. We welcome submissions of original research papers, either theoretical and/or experimental.

The aim of the journal is to report new physical discoveries via any of these approaches. Manuscripts that limit themselves to reporting results without advancing our fundamental understanding of physics will not be considered for publication. Papers clearly on the applied physics side will not be considered and may be directed to EPJ Applied Physics (EPJAP) or EPJ Plus. Likewise, manuscripts reporting results on complex systems without a relation to physics may be redirected to EPJ Data Science (EPJDS).

Article Categories

• Research Articles
• Colloquia
• Topical Reviews
• Roadmap Articles
• Perspective Articles

Research Articles contain complete and comprehensive report of original research.

Colloquia describe the development of new areas of research or the impact of new and promising experimental or theoretical methods in the fields that are within the spectrum of topics covered by the respective journals. While not as extensive and complete as reviews in the usual sense, they are intended to suitably introduce new research directions and techniques in their early stages of development, and to a wider audience. There is no explicit constraint regarding the length of such manuscripts, although 20 printed pages would be the most usual length. All invited/submitted manuscripts will undergo the same refereeing procedure as all other contributions submitted to the journal. For invited colloquium papers, authors will receive a honorarium of EUR 400,-- upon publication. Colloquium papers are generally solicited by the journal editors. Authors wishing to submit a colloquium paper are advised to contact the Editors-in-Chief.

Topical Reviews provide a comprehensive and extensive summary of recent research results in a field that is within the spectrum of topics covered by EPJ B and are of current interest to a broader audience. A topical review should aim to summarize the pertinent experimental, theoretical, and computational results obtained by the key research groups working in the field in the past 10 years. Historical reviews of an entire sub-field of physics are discouraged. There is no explicit constraint regarding the length of such manuscripts, although 35 printed pages would be the most usual length. All invited/submitted manuscripts will undergo the same refereeing procedure as all other contributions submitted to the journal. For invited topical review papers, authors will receive a honorarium of EUR 400,-- upon publication. Topical review papers are generally solicited by the journal editors. Authors wishing to submit a topical review paper are advised to contact the Editors-in-Chief.

Roadmap Articles are a type of collaborative review papers where a group of authors outlines recent developments and new direction in a specific field. Roadmap papers are structured in multiple sections, each written by different authors. Roadmap authors can send an inquire to the editorial office providing tentative tile, abstract and authors list.

The Perspective Article type denotes a scholarly review and discussion of primary research that does not meet the criteria for a review. This could be because the scope is too narrow, or because the piece is intended to provoke a discussion of a controversial position, speculative hypothesis, or alternative interpretations of existing work.
