# Episode Title Description People Date
1 DMRG in Quantum Chemistry: From its relation to traditional methods to n-orbital density matrices and beyond In my talk I will attempt to provide an overview on the application of the density matrix renormalization group (DMRG) algorithm in quantum chemistry. Markus Reiher 21 Oct 2016
2 (Almost) 25 Years of DMRG - What Is It About? In this talk, I will introduce DMRG both from the historical (statistical) and modern (matrix product state) perspective, highlighting why it has become the method of choice for one-dimensional quantum systems in and out of equilibrium. Ulrich Schollwöck 21 Oct 2016
3 Openness of a Many-fermion Quantum System from the Generalized Pauli Principle Information about the interaction of a many-electron quantum system with its environment is encoded within the one-electron density matrix (1-RDM). Romit Chakraborty 21 Oct 2016
4 Generalized Pauli Constraints in Reduced Density Matrix Functional Theory Reduced Density Matrix Functional Theory is a method that relies on the 1-1 correspondence between the ground state wavefunction of many electron systems and the first order reduced density matrix(1RDM) and uses the second one as its fundamental valuable. Iris Theophilou 21 Oct 2016
5 Physical Meaning of Natural Orbitals and Natural Occupation Numbers We show that the success of reduced density-matrix functional theory in describing molecular dissociation lies in the flexibility provided by fractional occupation numbers while the role of the natural orbitals is minor. Nicole Helbig 21 Oct 2016
6 Entanglement Spectroscopy and its application to the fractional quantum Hall phases In this talk, we will give an overview of the entanglement spectroscopy with a focus on to the fractional quantum Hall phases. Nicolas Regnault 11 Oct 2016
