Individual bias and fluctuations in collective decision making: from algorithms to Hamiltonians
Petro Sarkanych, Mariana Krasnytska, Luis Gómez-Nava +2
In this paper, we reconsider the spin model suggested recently to understand some features of collective decision making among higher organisms [A.T. Hartnett et al., Phys. Rev. Le…
Potts Model with Invisible States: A Review
Mariana Krasnytska, Petro Sarkanych, Bertrand Berche +2
The Potts model with invisible states was introduced to explain discrepancies between theoretical predictions and experimental observations of phase transitions in some systems whe…
On the new universality class in structurally disordered -vector model with long-range interactions
Dmytro Shapoval, Maxym Dudka, Yurij Holovatch
We study a stability border of a region where nontrivial critical behaviour of an -vector model with long-range power-law decaying interactions is induced by the presence of a s…
Effective and asymptotic criticality of structurally disordered magnets
Maxym Dudka, Mariana Krasnytska, Juan J. Ruiz-Lorenzo +1
Changes in magnetic critical behaviour of quenched structurally-disordered magnets are usually exemplified in experiments and in MC simulations by diluted systems consisting of mag…
Phase transitions above the upper critical dimension
Bertrand Berche, Tim Ellis, Yurij Holovatch +1
These lecture notes provide an overview of the renormalization group (RG) as a successful framework to understand critical phenomena above the upper critical dimension …
Schottky's forgotten step to the Ising model
Reinhard Folk, Yurij Holovatch
A longstanding problem in natural science and later in physics was the understanding of the existence of ferromagnetism and its disappearance under heating to high temperatures. Al…
