International workshop on "Reduced Density-Matrix Functional Theory: Improving its foundation and extending its scope"
CECAM-HQ-EPFL, Lausanne, 6 -9 October 2020
organized by Carlos L. Benavides-Riveros, Hardy Gross and Christian Schilling
This international workshop will discuss and explore new aspects and challenges in Reduced Density Matrix Functional Theory (RDMFT). The main aim is to bring together leading experts in RDMFT and related fields to improve the foundation of RDMFT and to extend its scope. The workshop comprises the following thematic blocks: (i) Universal features of the exact functional & role of the one- and two-body N-representability conditions, (ii) RDMFT for translationally invariant lattice systems and (iii) Extension of RDMFT to excited states, finite-temperature and time-evolving systems.
San Sebastian, 15-18 June 2020
organized by David A. Mazziotti, Mario Piris and Christian Schilling
The interdisciplinary workshop brings together experts from the quantum sciences, particularly quantum chemistry and quantum information theory to elaborate on conceptual aspects of interacting quantum many-fermion systems. The aim is to discuss recent ideas and identify open challenges related to the determination of the energy and properties of interacting fermions in terms of reduced density matrices (RDMs). Topics will explore the theory and applications of both ground and excited states as well as time-dependent processes. The workshop comprises the following connected thematic blocks:
(I) geometry of RDMs & concept of fermionic correlation/entanglement
(II) 1- & 2-body N-representability problem
(III) 1RDM- & 2RDM-functional theory (ground states)
(IV) excited states & time-evolution
International workshop on "New challenges in Reduced Density Matrix Functional Theory: Symmetries, time-evolution and entanglement"
CECAM-HQ-EPFL, Lausanne, 26-29 September 2017
organized by Carlos L. Benavides-Riveros, Hardy Gross, Miguel A. L. Marques and Christian Schilling
This international workshop discussed and explored new aspects and challenges in Reduced Density Matrix Functional Theory (RDMFT). The main aim was to bring together leading experts in the field to address and carefully discuss open challenges such as implementation of 1-particle symmetries, extension of RDMFT to open-shell atoms and molecules, time-evolution, entanglement and new insights about RDMFT from recent progress on the 1-body N-representability problem.
Pauli2016: International workshop on "Reduced Density Matrices in Quantum Physics and Role of Fermionic Exchange Symmetry"
University of Oxford, 12-15 April 2016
organized by Christian Schilling and Vlatko Vedral
The interdisciplinary workshop brought together experts in quantum science, as e.g. quantum information theory, quantum chemistry, solid state physics and mathematical physics. The aim was to explore from a conceptual viewpoint the influence of the fermionic exchange symmetry and its consequences for the reduced 1-and 2-fermion picture. In particular, a better understanding should be developed of how the conflict of energy minimization and antisymmetry of the N-fermion quantum state leads to simplified descriptions of fermionic ground states. The emphasis laid on the four subjects:
(I) particle exchange symmetry
(II) reduced density matrices
(III) generalized Pauli constraints
(IV) degeneracy pressure and numerical methods
