PAIR (Prompt Automatic Iterative Refinement)

PAIR (Prompt Automatic Iterative Refinement) is an automated black-box jailbreak method, introduced in 2023, in which an attacker LLM iteratively rewrites prompts until a target LLM produces responses its safety training was meant to refuse.

Pair bond

Pair bond: a selective, enduring social relationship between two adults in a breeding pair, studied via prairie voles; oxytocin, vasopressin, and dopamine in reward circuitry; distinct from social or genetic monogamy.

Pair distribution function

The pair distribution function is a real-space structural measure giving the probability of finding atom pairs a distance r apart, used for glasses, liquids, and nanomaterials.

Pair plasma

A pair plasma is a quasi-neutral plasma of particles and their antiparticles, typically electrons and positrons, with no ion component, found in pulsar magnetospheres, relativistic jets, and gamma-ray bursts.

Pair production

Pair production, or pair creation, converts a high-energy photon into an electron and a positron in the field of a nucleus, requiring at least 1.022 MeV.

Pair production cascade

A pair production cascade is an electromagnetic cascade in intergalactic space where TeV gamma rays absorbed by the extragalactic background light regenerate GeV gamma rays through inverse Compton scattering.

Pair-density wave

The pair-density wave (PDW) is a proposed superconducting state in which Cooper pairs carry finite momentum, making the superconducting order parameter oscillate in space rather than stay uniform.

Pair-density-wave order in cuprates

Pair-density-wave (PDW) order in cuprates is a proposed superconducting state in which the order parameter oscillates spatially, giving Cooper pairs finite momentum, proposed as a mother order behind charge order and the pseudogap.

Pair-instability mass gap

The pair-instability mass gap is a predicted range of black hole masses, roughly 50 to 130 solar masses, where pair-instability supernovae disrupt very massive stars completely.

Pair-instability supernova

A pair-instability supernova (PISN) is a thermonuclear explosion that completely disrupts a very massive star when pair creation removes core pressure support, leaving no neutron star or black hole behind.
