This is predicted for the most intense lasers and is believed to fill pulsar magnetospheres with pair plasma.","title":"QED pair cascades in lasers and pulsars","topic_ref":null,"why":"Cascades may set an upper limit on attainable laser intensity and supply the pair plasma that produces pulsar radio emission and pulsar wind nebulae."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"3d0d7926a3332ed1d5c98bce793a625e7064aa0a336ed90e374a074aaf4cfe04","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"70d80903f54931a10aecd2bb6a8203bd7967c14a8123534550a519cba9bfcd87","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"RMbTTBkmQm6ZBxLS4ejhoONhVfCdZNR5C8R3ZxBc5aPf_bHWFA_RW25hXvbYgqTiMzfkHwOWEQLKmdA17n4eBA"},"schema":"pubphys.envelope/1"},"record_hash":"3d0d7926a3332ed1d5c98bce793a625e7064aa0a336ed90e374a074aaf4cfe04","leaf_index":303}
