Time irreversibility in Statistical Mechanics
Dominique Levesque, Nicolas Sourlas
One of the important questions in statistical mechanics is how irreversibility (time's arrow) occurs when Newton equations of motion are time reversal invariant. One objection to i…
Finite-size scaling of the random-field Ising model above the upper critical dimension
Nikolaos G. Fytas, Victor Martin-Mayor, Giorgio Parisi +2
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 sugge…
Fermionic duality
Nicolas Sourlas
Duality transformations play a very important role in theoretical physics. In this paper I propose new duality transformations for fermionic theories. They map the strong coupling…
On the critical exponent of the 5D random-field Ising model
Nikolaos G. Fytas, Victor Martin-Mayor, Giorgio Parisi +2
We present a complementary estimation of the critical exponent of the specific heat of the 5D random-field Ising model from zero-temperature numerical simulations. Our result $…
Evidence for Supersymmetry in the Random-Field Ising Model at D = 5
Nikolaos G. Fytas, Victor Martin-Mayor, Giorgio Parisi +2
We provide a non-trivial test of supersymmetry in the random-field Ising model at five spatial dimensions, by means of extensive zero-temperature numerical simulations. Indeed, sup…
The expansion and Universality in three dimensions
Nicolas Sourlas
It has been observed that the clasification into universality classes of critical behaviour, as established by perturbative renormalization group in the viscinity of four or six di…
