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.

(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.

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).

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.

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.
