Struct BcsGap 

pub struct BcsGap {
    pub gap_energy: f64,
    pub density_of_states: f64,
    pub critical_temperature: f64,
}

BCS (Bardeen–Cooper–Schrieffer) energy gap model.

The BCS gap Δ(T) determines the binding energy of Cooper pairs.

Fields

gap_energy: f64

Zero-temperature gap energy Δ(0) (J).

density_of_states: f64

Electronic density of states at the Fermi level N(0) (J⁻¹ m⁻³).

critical_temperature: f64

Critical temperature T_c (K).

Implementations

impl BcsGap

pub fn new( gap_energy: f64, density_of_states: f64, critical_temperature: f64, ) -> Self

Construct from zero-temperature gap, density of states, and T_c.

pub fn from_tc(critical_temperature: f64, density_of_states: f64) -> Self

Construct from T_c using the BCS relation Δ(0) = 1.764 k_B T_c.

pub fn compute_gap(&self, temperature: f64) -> f64

Compute the temperature-dependent gap Δ(T) using the BCS interpolation:

Δ(T) ≈ Δ(0) · tanh(1.74 √((T_c/T) - 1)) for T < T_c

Returns 0.0 for T ≥ T_c.

pub fn normalised_gap(&self, temperature: f64) -> f64

Normalised gap Δ(T)/Δ(0).
