Adding quantum tunneling between ice configurations is predicted to give a quantum spin liquid with emergent light, a photon-like wave of an internal gauge field.","title":"Spin ice, monopoles and quantum spin ice","topic_ref":null,"why":"Spin ice is the cleanest material setting for fractional particles and emergent electromagnetism in three dimensions."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"52cddd9c3d75748e46e41f34a20edd20c81c928cc0056fa7e4de59ade0220e82","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"ed42584586d15dbbd45d3c8843190744fbb85e7360fe5d0cb48bf041a871067f","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"PI35NSCJXdDxTAz85tZ0VxtH9sg80k_0NUpBVDYQRtsOY2DF2iILLdG97BWmw8gc65bxO_ucgg4Zz-ZU-1YGAA"},"schema":"pubphys.envelope/1"},"record_hash":"52cddd9c3d75748e46e41f34a20edd20c81c928cc0056fa7e4de59ade0220e82","leaf_index":172}
