Eigenvalue crossing as a phase transition in relaxation dynamics
Gianluca Teza, Ran Yaacoby, Oren Raz
When a system's parameter is abruptly changed, a relaxation towards the new equilibrium of the system follows. We show that a crossing between the second and third eigenvalues of t…
On-Site Potential Creates Complexity in Systems with Disordered Coupling
Igor Gershenzon, Bertrand Lacroix-A-Chez-Toine, Oren Raz +2
We calculate the average number of critical points of the energy landscape of a many-body system with disordered two-body interactions and a weak on-site p…
Landau Theory for the Mpemba Effect Through Phase Transitions
Roi Holtzman, Oren Raz
The Mpemba effect describes the situation in which a hot system cools faster than an identical copy that is initiated at a colder temperature. In many of the experimental observati…
Far from equilibrium relaxation in the weak coupling limit
Ran Yaacoby, Oren Raz, Gianluca Teza
It is commonly assumed that a large system, weakly coupled to a thermal environment through its boundaries, relaxes quasistatically towards the new equilibrium even when the temper…
Echo chambers in the Ising model and implications on the mean magnetization
Talia Baravi, Ofer Feinerman, Oren Raz
The echo-chamber effect is a common term in opinion dynamic modeling to describe how a person's opinion might be artificially enhanced as it is reflected back at her through social…
Relaxation shortcuts through boundary coupling
Gianluca Teza, Ran Yaacoby, Oren Raz
When a hot system cools down faster than an equivalent cold one, it exhibits the Mpemba Effect. This counterintuitive phenomenon was observed in several systems including water, ma…
