Ferrodark solitonsin a spinor superfluid
Exact propagating topological solitons are found in the easy-plane phaseof ferromagnetic spin-1 Bose-Einstein condensates, manifesting themselves askinks in the transverse magnetization. Propagation is only possible when thesymmetry-breaking longitudinal magnetic field is applied. Such solitons arereferred to as ferrodark solitons and have two types: a low energy branch withpositive inertial mass and a higher energy branch with negative inertial mass.Both types become identical at the maximum speed, a new speed bound that isdifferent from speed limits set by the elementary excitations. The physical mass,which accounts for the number density dip, is negative for both types. In afinite one-dimensional system subject to a linear potential, the solitonundergoes oscillations caused by transitions between the two types occurring atthe maximum speed. I will also present some recent progress on thestability of line ferrodark solitons in a 2D system.

Analogue and digital quantum simulation: state of the art and opportunities
There has been impressive recent progress in developing highly controlled quantum systems, ranging from superconducting qubits to neutral atoms in tweezer arrays. These systems provide a route to medium-scale quantum computing, but also the possibility to build and study models of many-body systems. These range from electrons in solid state physics and materials across to toy models for information spreading in black holes (made possible by long-range interactions). This impressive progress had led to new opportunities for studying basic science, but has also opened pathways towards making quantum simulation useful in solving problems from chemistry, materials and wider fields.
I will give an introduction to the state of the art in these systems, illustrated with our recent theoretical work on fast scrambling of quantum information in systems with long-range interactions. I will also discuss the opportunities and challenges associated with important questions, including (1) To which degree can analogue devices be quantitatively reliable? And (2) when can we use these systems to give us access to useful information that we cannot compute with conventional supercomputers?
Thu 26 September, 11am: DWC - “The Many” Seminar – Prof.Han Pu (Rice University)
In person: Massey University Albany IC3.05, contact: Joachim Brand

1D spinor quantum gas in the strongly interacting regime
1Dmany-body systems have revealed a number of intriguing and unique quantum properties. The advent of cold atoms make it possible to realize such 1Dsystems in controllable manner in the lab. In this talk, I will review our recent work on 1D spinor quantum gas in the strongly interacting regime. I will show that such strongly interacting system can be mapped to a weakly interacting one, which can then be treated using a perturbation approach. This mapping allows us to see clearly the interplay between the spin and the charge degrees of freedom, the effects of quantum statistics, and forms the basis for efficient computation of important quantities such as one-body density matrix, the momentum distribution, etc.
More seminars will be added as information becomes available. Anyone interested can attend the above seminars.

Short Bio of Max Kennedy:
Max Kennedy, PhD, FIChemE, FEngNZ (Ret), FNZIC, was the Manager of Contestable Investments at the Ministry of Business, Innovation and Employment (MBIE) for 12 years. This included managing the Endeavour Fund (New Zealand’s largest contestable research fund), the industry-led Partnership Fund, the Pre-Seed Acceleration Fund, and the Vision Mātauranga Capability Fund. Max also led MBIE’s COVID Innovation Acceleration Fund to support research to respond to the COVID-19pandemic.
Prior to this Max was Research and Development Strategy Manager at Meat and Wool NZ Ltd (MWNZ), directing MWNZ consortia research investment in nine companies or partnerships in the pastoral sector. Formerly he was the Chief Scientific Officer of IRL-Bio PharmLtd, a New Zealand-based fermentation contract manufacturer of active pharmaceutical ingredients for human clinical trials under cGMP conditions.
Max has served as Director on the Boards six technology companies and was on the Fermentation Advisory Board of the anti-malaria project of OneWorld Health (a not for profit pharmaceutical company based in San Francisco, USA). Max has been Chair of SCENZ – IChemE in New Zealand and Chair of The Australian and New Zealand Federation of Chemical Engineers (ANZFChE).

Basic Guide for a Visit to a Marae
Maori Values and principles - He Ritenga Guide
Kia ora koutou,
Puketeraki Marae would like us to know the following in relation to our visit to their marae tomorrow morning:
Given the rising Covid-19 situation, it will be a bit of an attenuated pōwhiri – so no hongi and more of a ‘wave’. Also, kai will be served on separate plates for individuals.
Before entering the marae please remove your shoes, ngā mihi.
The Dodd-Walls Centre research focuses around photonics, the manipulation of light at the most fundamental, quantum level, and the control and manipulation of matter at the atomic scale, through the use of light.
