Configurational temperature in active matter. I. Lines of invariant physics in the phase diagram of the Ornstein-Uhlenbeck model. [PDF]
Physical Review E, 2022 This paper shows that the configurational temperature of liquid-state theory, T_{conf}, defines an energy scale, which can be used for adjusting model parameters of active Ornstein-Uhlenbeck particle (AOUP) models in order to achieve approximately ...

PELICAN: Permutation Equivariant and Lorentz Invariant or Covariant Aggregator Network for Particle Physics [PDF]
arXiv.org, 2022 Many current approaches to machine learning in particle physics use generic architectures that require large numbers of parameters and disregard underlying physics principles, limiting their applicability as scientific modeling tools.

High-dimensional and Permutation Invariant Anomaly Detection [PDF]
SciPost Physics, 2023 Methods for anomaly detection of new physics processes are often limited to low-dimensional spaces due to the difficulty of learning high-dimensional probability densities. Particularly at the constituent level, incorporating desirable properties such as

Radial bound states in the continuum for polarization-invariant nanophotonics [PDF]
Nature Communications, 2022 All-dielectric nanophotonics underpinned by the physics of bound states in the continuum (BICs) have demonstrated breakthrough applications in nanoscale light manipulation, frequency conversion and optical sensing.

Carroll contractions of Lorentz-invariant theories [PDF]
Journal of High Energy Physics, 2021 We consider Carroll-invariant limits of Lorentz-invariant field theories. We show that just as in the case of electromagnetism, there are two inequivalent limits, one “electric” and the other “magnetic”.

Classical gravitational scattering from a gauge-invariant double copy [PDF]
Journal of High Energy Physics, 2021 We propose a method to compute the scattering angle for classical black hole scattering directly from two massive particle irreducible diagrams in a heavy-mass effective field theory approach to general relativity, without the need of subtracting ...

Modular invariant dynamics and fermion mass hierarchies around τ = i [PDF]
Journal of High Energy Physics, 2021 We discuss fermion mass hierarchies within modular invariant flavour models. We analyse the neighbourhood of the self-dual point τ = i, where modular invariant theories possess a residual Z4 invariance.

Gauge-invariant and anyonic-symmetric autoregressive neural network for quantum lattice models [PDF]
Physical Review Research, 2021 Symmetries such as gauge invariance and anyonic symmetry play a crucial role in quantum many-body physics. We develop a general approach to constructing gauge invariant or anyonic symmetric autoregressive neural network quantum states, including a wide ...
