### Recent Highlight

In September 2020 I was invited to give a theory review of heavy exotic spectroscopy for the 19th international Beauty 2020 Conference. Below are the video and slides of my review talk, given remotely during the covid pandemic.

# Quantum Computing & Quantum Information Science

### Recent Highlight

In Digitizing Gauge Fields: Lattice Monte Carlo Results for Future Quantum Computers, my collaborators and I explored a novel digitization methodology for implementing gauge fields on a digital quantum computer and encouragingly found that in a $$(3+1)$$-dimensional $$SU(2)$$ gauge theory, each gauge link can be represented by $$\mathcal{O}(10)$$ (qu)bits, from which we estimate that a $$16^3$$ $$SU(2)$$ lattice could be simulated with no more than $$\mathcal{O}(105)$$ (qu)bits. These are very promisingly results for the NISQ quantum computing era.

# Education

### Recent Highlight

By Teaching Quantum Computing to High School Students in classrooms, my collaborators and I show evidence of the successful efficacy of the "Quantum Computing for High School Students" book that I co-authored. This is emphasised in Fig. 4 of our work.

# AI And Machine Learning

### Recent Highlight

In Using Deepfakes to Hack the Unconscious Mind, my collaborators and I show that genuine and deepfake (AI manipulated/generated material - potentially of a specific human target) audio/video material effects humans very similarly. Specifically, we find that a substantial number of humans cannot detect a deepfake if shown, that deepfakes and genuine material effect humans to similar extents (shown below), and even if a human knows that they are shown a deepfake, then they can still be effected by it unconsciously. This allows a dangerous failure mode in the post-truth era.

# Statistical Physics & Computational Chemistry

### Recent Highlight

In these works, my collaborators and I study the two dimensional XY spin model, and apply statistical learning techniques in order to quantify the stationary points. Of particular importance are the minima and the index-1 stationary points, with which, we can visualise the disconnectivity graph in order to understand how transitions between states of matter occur. We also formulate a new algorithm, the inversion-relaxation technique, which guarantees to find all stationary points and is also far more efficient than previous methods.

# H-Index

Due to the breadth and interdisciplinary nature of my research, websites like inspires, arxiv, and google scholar will underestimate my citation record and therefore h-index. As an example, inspire will only include high-energy physics publications in their citation count. Consequently, my statistical physics/chemistry/education/AI work will not count towards the inspires h-index count, and the inspires citation will only be a lower bound of my combined work. Similar effects happen with google scholar. It is thus necessary to scrape multiple websites like google scholar/inspires/etc to obtain an accurate citation count, and combine these to form an accurate h-index. This is also straightforward to eyeball the websites and observe this effect.
