Struct ScalingRelations 

pub struct ScalingRelations {
    pub exp: CriticalExponents,
}

Verification of thermodynamic scaling relations from critical exponents.

The four classical relations among {α, β, γ, δ, ν, η, d}:

• Rushbrooke: α + 2β + γ = 2
• Widom: γ = β(δ − 1)
• Fisher: γ = (2 − η) ν
• Josephson: 2 − α = d ν (hyperscaling)

Fields

exp: CriticalExponents

Critical exponents to check.

Implementations

impl ScalingRelations

pub fn new(exp: CriticalExponents) -> Self

Construct from a set of critical exponents.

pub fn rushbrooke(&self) -> (f64, f64)

Rushbrooke identity: α + 2β + γ = 2. Returns (lhs, rhs=2).

pub fn widom(&self) -> (f64, f64)

Widom identity: γ = β(δ − 1). Returns (lhs=γ, rhs=β(δ−1)).

pub fn fisher(&self) -> (f64, f64)

Fisher identity: γ = (2 − η) ν. Returns (lhs=γ, rhs).

pub fn josephson(&self) -> (f64, f64)

Josephson (hyperscaling) identity: 2 − α = d ν. Returns (lhs, rhs).

pub fn check_all(&self, tol: f64) -> (bool, bool, bool, bool)

Check all four relations within tolerance tol.

Returns (rushbrooke_ok, widom_ok, fisher_ok, josephson_ok).
