EPJ B Topical Issue: Recent developments in the functional renormalization group approach to correlated electron systems

Guest Editors: Carsten Honerkamp, Dante Kennes, Volker Meden, Michael Scherer and Ronny Thomale.

Submissions are invited for a Topical Issue of EPJ B on Recent developments in the functional renormalization group approach to correlated electron systems.

Within the scope of condensed matter research, the functional renormalization group approach is a quantum many-body method that combines the possibility to explore correlated electronic states and competing orders in a broad range of complex quantum materials. It embodies the transformative potential of a combined analytical and numerical toolkit aiming at quantitative predictions of collective phenomena in quantum many-body systems.

In the last decade, the functional renormalization group approach has witnessed major methodological advances and extensions. This includes aspects of the renormalization group formulation, increased computer power and enhanced interlinks to ab initio quantum material methods, extensions to strongly correlated electronic models, and electronic systems out of equilibrium.

Since those developments of functional renormalization take place in a vibrant environment of groundbreaking experimental advances in novel correlated quantum material synthesis, there is a natural call for broadening the basis of FRG practitioners and a continued refinement of this versatile theoretical tool. The focus issue we put forward attempts to contribute to this ambition, as we intend to collect recent methodological advances in functional renormalization group. The plan is that such a synopsis of state-of-the-art FRG implementations and applications will support interested scientists at entering the field. In doing so, the focus issue intends to induce a paradigm shift of the reception of FRG in the condensed matter community, and to elevate the FRG to an approach of ubiquitous use in contemporary research on correlated electron systems and beyond.

Topics to be covered include but are not limited to:

  • Code development for functional renormalization group implementations
  • Algorithmic adaption of functional renormalization group (truncated unity, multi-loop, patch-RG, singular mode etc.)
  • Quantum materials analysis through functional renormalization group

These general topics may be interpreted in the broadest sense, and the issue is open to everyone working in related fields. The topical issue is now open for submission of contributions. Original research papers, review articles, and white paper/roadmap articles are all welcomed. We invite contributors to communicate their intention to submit manuscripts for this Topical Issue to the Guest Editors as soon as possible. Please provide the tentative title of the paper and a short abstract. The full manuscripts should be submitted before the deadline directly to the EPJ B Editorial Office at https://www.editorialmanager.com/epjb/

Deadline for submission: January 15, 2022

Submissions should be clearly identified as intended for the Topical Issue on “Recent developments in the functional renormalization group approach to correlated electron systems”. Papers will be published continuously and will appear as soon as accepted on the journal website. The electronic version of the Topical Issue will contain all accepted papers in the order of publication. All submitted papers will be refereed according to the usual high standards of the journal. More information about EPJB, including instructions for authors is available at http://epjb.epj.org/.
