Hydrodynamics of Quantum Many-Body Systems Out of Equilibrium

Can we apply hydrodynamics to systems with extensively many conservation laws
Oxford Physics Public Lectures

The Many Universes of Quantum Materials

Professor Stephen Blundell explores the many universes of quantum materials for the 2019 Quantum Materials Public Lecture.

Oxford Mathematics and the Clay Mathematics Institute Public Lectures: Roger Penrose - Eschermatics

In this lecture Roger Penrose uses M.C Escher's work to illustrate and explain important mathematical ideas and their connections to the visual arts.
Big Questions - with Oxford Sparks

How do you become an astronaut?

Millions dream of being an astronaut, but how many of us have what it takes? In this episode of the Oxford Sparks Big Question's podcast, we visit Merritt Moore, quantum physicist from The University of Oxford, to ask: How do you become an astronaut?

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.
Journey of a Molecular Detective; David Sherratt

(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).

Fermionic Exchange Symmetry: Quantifying its Influence beyond Pauli’s Exclusion Principle

The Pauli exclusion principle has a strong impact on the properties and the behavior of most fermionic quantum systems. Remarkably, even stronger restrictions on fermionic natural occupation numbers follow from the fermionic exchange symmetry.

Introduction and Overview of the Reduced Density Matrix Functional Theory

In this presentation, we review the theoretical foundations of RDMFT the most successful approximations and extensions, we assess present-day functionals on applications to molecular and periodic systems and we discuss the challenges and future prospect
Journey of a Molecular Detective; David Sherratt

Quantum Marginal Problem and Generalized Pauli Constraints

I will give an introduction to the univariate quantum marginal problem using an elementary mathematical point of view. In particular, I will explain how extremality of the local spectrum carries structural information about the global wave function.
Journey of a Molecular Detective; David Sherratt

Two-electron Reduced Density Matrices in Quantum Chemistry and Physics

Strongly correlated quantum systems are not easily described with conventional quantum chemistry formalism because the number of non-negligible configurations grows exponen- tially with the number of orbitals actively participating in the correlation.
Journey of a Molecular Detective; David Sherratt

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.
Journey of a Molecular Detective; David Sherratt

Why should anyone care about computing with anyons?

In this talk Jiannis Pachos discusses a variety of different topics starting from characterizing knot invariants, their quantum simulation with exotic particles called anyons and finally the possible realization of anyons in the laboratory.

Quantum Geometry, Exclusion Statistics, and the Geometry of "Flux Attachment" in 2D Landau levels

Duncan Haldane talks about Quantum Geometry, Exclusion Statistics, and the Geometry of "Flux Attachment" in 2D Landau levels.

Exchange symmetry and anyon virial coefficients

This talk mentions some aspects of the theory of identical particles, for example, treating neutrons and protons as identical particles distinguished by a quantum number called isotopic spin.
Journey of a Molecular Detective; David Sherratt

Exchange statistics - Basic concepts

In this talk Jon Magne Leinaas from University of Oslo reviews some of the basic ideas and questions related to the exchange symmetry of identical particles.
Big Questions - with Oxford Sparks

'Light' Part 2 - Harnessing a single photon

What's the use of just one photon, the smallest bit of light? And what does it take to study it?
Oxford Sparks: bringing science to life

Run for Your Light

You may have heard the word “quantum” bandied around a lot. But what does it mean? In this animation we take a look at how the photon – the quantum particle of light – is being harnessed to help create new technologies like quantum computers.
