Journal Article
Delouche, O., Miró, J. E., & Ingoldby, J. (2025). Testing the RG-flow M (3, 10) + ϕ 1, 7 → M (3, 8) with Hamiltonian Truncation. Journal of High Energy Physics, 2025(4), Article 144. https://doi.org/10.1007/jhep04%282025%29144

Hamiltonian Truncation (HT) methods provide a powerful numerical approach for investigating strongly coupled QFTs. In this work, we develop HT techniques to analyse a specific Renormalization Group (RG) flow recently proposed in refs. [1, 2–3]. These...

(2024). Stealth dark matter spectrum using Laplacian Heaviside smearing and irreducible representations. Physical Review D, 110(9), https://doi.org/10.1103/physrevd.110.095001

We present nonperturbative lattice calculations in the quenched approximation of the low-lying meson and baryon spectrum of the SU(4) gauge theory with fundamental fermion constituents. This theory is one instance of stealth dark matter, a class of s... Read More about Stealth dark matter spectrum using Laplacian Heaviside smearing and irreducible representations.

Enhancing quantum field theory simulations on NISQ devices with Hamiltonian truncation (2024)
Journal Article

Quantum computers can efficiently simulate highly entangled quantum systems, offering a solution to challenges facing classical simulation of quantum field theories (QFTs). This paper presents an alternative to traditional methods for simulating the... Read More about Enhancing quantum field theory simulations on NISQ devices with Hamiltonian truncation.

Dilaton forbidden dark matter (2024)
Journal Article
Appelquist, T., Ingoldby, J., & Piai, M. (2024). Dilaton forbidden dark matter. Physical Review D, 110(3), Article 035013. https://doi.org/10.1103/physrevd.110.035013

Dilaton effective field theory (dEFT) describes the long distance behavior of certain confining, near-conformal gauge theories that have been studied via lattice computation. Pseudo-Nambu- Goldstone bosons (pNGBs), emerging from the breaking of appro... Read More about Dilaton forbidden dark matter.

Hamiltonian truncation crafted for UV-divergent QFTs (2024)
Journal Article
Delouche, O., Elias Miro, J., & Ingoldby, J. (2024). Hamiltonian truncation crafted for UV-divergent QFTs. SciPost Physics, 16, Article 105. https://doi.org/10.21468/scipostphys.16.4.105

We develop the theory of Hamiltonian Truncation (HT) to systematically study RG flows that require the renormalization of coupling constants. This is a necessary step towards making HT a fully general method for QFT calculations. We apply this theory... Read More about Hamiltonian truncation crafted for UV-divergent QFTs.
