Parisi-Sourlas supersymmetry in random field models

A Kaviraj, S Rychkov, E Trevisani - Physical review letters, 2022 - APS
By the Parisi-Sourlas conjecture, the critical point of a theory with random field (RF) disorder
is described by a supersymmeric (SUSY) conformal field theory (CFT), related to ad-2 …

Random Field Ising Model and Parisi-Sourlas supersymmetry. Part I. Supersymmetric CFT

A Kaviraj, S Rychkov, E Trevisani - Journal of High Energy Physics, 2020 - Springer
A bstract Quenched disorder is very important but notoriously hard. In 1979, Parisi and
Sourlas proposed an interesting and powerful conjecture about the infrared fixed points with …

The quantum transition of the two-dimensional Ising spin glass

M Bernaschi, I González-Adalid Pemartín… - Nature, 2024 - nature.com
Quantum annealers are commercial devices that aim to solve very hard computational
problems, typically those involving spin glasses,. Just as in metallurgic annealing, in which a …

Renormalization group for measurement and entanglement phase transitions

A Nahum, KJ Wiese - Physical Review B, 2023 - APS
We analyze the renormalization group (RG) flows of two effective Lagrangians, one for
measurement-induced transitions of monitored quantum systems and one for entanglement …

Finite-size scaling of the random-field Ising model above the upper critical dimension

NG Fytas, V Martín-Mayor, G Parisi, M Picco, N Sourlas - Physical Review E, 2023 - APS
Finite-size scaling above the upper critical dimension is a long-standing puzzle in the field of
statistical physics. Even for pure systems various scaling theories have been suggested …

Random-field Ising and O(N) models: theoretical description through the functional renormalization group

G Tarjus, M Tissier - The European Physical Journal B, 2020 - Springer
We review the theoretical description of the random field Ising and O (N) models obtained

Random field ϕ3 model and Parisi-Sourlas supersymmetry

A Kaviraj, E Trevisani - Journal of High Energy Physics, 2022 - Springer
A bstract We use the RG framework set up in [1] to explore the ϕ 3 theory with a random field
interaction. According to the Parisi-Sourlas conjecture this theory admits a fixed point with …
