Berezinskii-Kosterlitz-Thouless phase transitions with long-range couplings

G Giachetti, N Defenu, S Ruffo, A Trombettoni - Physical Review Letters, 2021 - APS
The Berezinskii-Kosterlitz-Thouless (BKT) transition is the paradigmatic example of a
topological phase transition without symmetry breaking, where a quasiordered phase …

Berezinskii-Kosterlitz-Thouless transitions in classical and quantum long-range systems

G Giachetti, A Trombettoni, S Ruffo, N Defenu - Physical Review B, 2022 - APS
In the past decades, considerable efforts have been made to understand the critical features
of both classical and quantum long-range (LR) interacting models. The case of the …

Statistical mechanics of coupled supercooled liquids in finite dimensions

B Guiselin, L Berthier, G Tarjus - SciPost Physics, 2022 - scipost.org
We study the statistical mechanics of supercooled liquids when the system evolves at a
temperature $ T $ with a field $\epsilon $ linearly coupled to its overlap with a reference …

Chaotic renormalization flow in the Potts model induced by long-range competition

K Jiang, J Qiao, Y Lan - Physical Review E, 2021 - APS
A proper description of spin glass remains a hard subject in theoretical physics and is
considered to be closely related to the emergence of chaos in the renormalization group …

Complex networks with tuneable spectral dimension as a universality playground

AP Millán, G Gori, F Battiston, T Enss, N Defenu - Physical Review Research, 2021 - APS
Universality is one of the key concepts in understanding critical phenomena. However, for
interacting inhomogeneous systems described by complex networks, a clear understanding …

3d large vector models at the boundary

L Di Pietro, E Lauria, P Niro - SciPost Physics, 2021 - scipost.org
We consider a 4d scalar field coupled to large $ N $ free or critical $ O (N) $ vector models,
either bosonic or fermionic, on a 3d boundary. We compute the $\beta $ function of the …

Unusual scaling for two-dimensional avalanches: Curing the faceting and scaling in the lower critical dimension

LX Hayden, A Raju, JP Sethna - Physical Review Research, 2019 - APS
The nonequilibrium random-field Ising model is well studied, yet there are outstanding
questions. In two dimensions, power-law scaling approaches fail and the critical disorder is …

Morphology of renormalization-group flow for the de Almeida–Thouless–Gardner universality class

P Charbonneau, Y Hu, A Raju, JP Sethna, S Yaida - Physical Review E, 2019 - APS
A replica-symmetry-breaking phase transition is predicted in a host of disordered media. The
criticality of the transition has, however, long been questioned below its upper critical …
