Fixed and Distributed Gene Expression Time Delays in Reaction-Diffusion Systems (2022)
Journal Article
Sargood, A., Gaffney, E. A., & Krause, A. L. (2022). Fixed and Distributed Gene Expression Time Delays in Reaction-Diffusion Systems. Bulletin of Mathematical Biology, 84(9), Article 98. https://doi.org/10.1007/s11538-022-01052-0

Time delays, modelling the process of intracellular gene expression, have been shown to have important impacts on the dynamics of pattern formation in reaction-diffusion systems. In particular, past work has shown that such time delays can shrink the... Read More about Fixed and Distributed Gene Expression Time Delays in Reaction-Diffusion Systems.

We propose worldsheet formulae for correlators of the massive non-linear sigma model (NLSM), scalar Dirac-Born-Infeld (DBI), and special Galileon (sGal) theories in de Sitter momentum space in terms of the recently proposed cosmological scattering eq...

Going beyond ER=EPR in the SYK model (2022)
Journal Article
Berkooz, M., Brukner, N., Ross, S. F., & Watanabe, M. (2022). Going beyond ER=EPR in the SYK model. Journal of High Energy Physics, 2022(8), Article 51. https://doi.org/10.1007/jhep08%282022%29051

We discuss generalizations of the TFD to a density matrix on the doubled Hilbert space. We suggest that a semiclassical wormhole corresponds to a certain class of such density matrices, and specify how they are constructed. Different semi-classical p...

Notes on the dynamics of noncommutative U(2) and commutative SU(3) instantons (2022)
Journal Article
Smith, D. J., Robson, C. J., & Farrow, J. A. (2022). Notes on the dynamics of noncommutative U(2) and commutative SU(3) instantons. Physical Review D, 106(4), Article 045001. https://doi.org/10.1103/physrevd.106.045001

We examine the dynamics of noncommutative instantons of instanton number 2 and commutative instantons of instanton number 3 in 5D super Yang-Mills theory. We begin by detailing the construction of the 1=4-Bogamolyni-Prasad-Somerfeldt instanton soluti... Read More about Notes on the dynamics of noncommutative U(2) and commutative SU(3) instantons.

Completely quantum neural networks (2022)
Journal Article

Artificial neural networks are at the heart of modern deep learning algorithms. We describe how to embed and train a general neural network in a quantum annealer without introducing any classical element in training. To implement the network on a sta...

New meromorphic CFTs from cosets (2022)
Journal Article
Das, A., Gowdigere, C. N., & Mukhi, S. (2022). New meromorphic CFTs from cosets. Journal of High Energy Physics, 2022(7), Article 152. https://doi.org/10.1007/jhep07%282022%29152

In recent years it has been understood that new rational CFTs can be discovered by applying the coset construction to meromorphic CFTs. Here we turn this approach around and show that the coset construction, together with the classification of meromo... Read More about New meromorphic CFTs from cosets.

We survey several results concerning the geometry and topology of threedimensional Alexandrov spaces with the aim of providing a panoramic and up-to-date view of the subject. In particular we present the classification of positively and nonnegatively... Read More about Three-dimensional Alexandrov spaces: A survey.

3d N = 4 Gauge Theories on an Elliptic Curve (2022)

This paper studies 3d N = 4 supersymmetric gauge theories on an elliptic curve, with the aim to provide a physical realisation of recent constructions in equivariant elliptic cohomology of symplectic resolutions. We first study the Berry connection f... Read More about 3d N = 4 Gauge Theories on an Elliptic Curve.

Refinement of anomalous dispersion correction parameters in single-crystal structure determinations (2022)

Correcting for anomalous dispersion is part of any refinement of an X-ray dif­fraction crystal structure determination. The procedure takes the inelastic scattering in the diffraction experiment into account. This X-ray absorption effect is specific...
