Kak otkryt' zazerkal'e s pomosh'yu gradusnika? (Detecting mirror matter on Earth via its thermal imprint on ordinary matter) Avtory: R. Foot, S. Mitra (stat'yu mozhno posmotret' zdes': cond-mat/0306561) |
Nekotoroe vremya nazad my rasskazyvali ob odnoi iz idei etih avtorov kasatel'no obnaruzheniya zerkal'nogo veshestva na Zemle (rekomenduem prochest' etu zametku prezhde chem prodolzhit'; sm. takzhe ih novuyu rabotu "Have mirror micrometeorites been detected?"). V dannoi stat'e Mitra i Fut prodolzhayut svoi izyskaniya....
"The idea is that a piece of mirror matter in the ground would draw in heat fromt he surrounding ordinary matter and radiate it away as mirror photons, thereby cooling the surrounding ordinary matter."
Ideya primerno takova. V nekotorom razumnom diapazone parametrov zerkal'noe veshestvo vzaimodeistvuet s obychnym ne tol'ko gravitacionno. Takie chasticy poluchayutsya v nekotoryh teoriyah s t.n. "zerkal'noi simmetriei". Esli temnaya materiya imeet elektromagnitnuyu svyaz' s obychnoi materiei na urovne ot 10-9 (odnoi milliardnoi) do 10-6 (odnoi millionoi) ot obychnoi kulonovskoi energii vidimogo veshestva, to eto oznachaet, chto zerkal'noe veshestvo mozhet byt' peremeshano s obychnym. Dalee, mozhno pokazat', chto pri etih parametrah zerkal'noe i obychnoe veshestvo nahodyatsya v teplovom ravnovesii. No (!), ohlazhdayas', zerkal'noe veshestvo izluchaet zerkal'nye fotony. Oni svobodno pokidayut issleduemyi obrazec (tak kak pogloshayushego ih zerkal'nogo veshestva ochen' malo). Znachit, vkrapleniya zerkal'noi materii budut ohlazhdat' (konechno, ochen' slabo) obychnoe veshestvo - poyavlyaetsya lishnii stok teplovoi energii. I eto mozhet byt' putem k registracii zerkal'noi materii.
Avtory takzhe obsuzhdayut, gde luchshe iskat'. Oni polagayut, chto naibolee veroyatno naiti ostatki "zerkal'nogo meteorita". Poetomu luchshe vsego iskat' v raionah padeniya kosmicheskih tel, v tom chisle obsuzhdaetsya Tungusskii meteorit. Zapodozrennye obrazcy, po mneniyu Mitry i Futa, sleduet dalee issledovat' predlozhennym imi metodom - s pomosh'yu centrifugi.
"In other words, one could use a thermal imaging detector (or even an old thermometer?) as a mirror matter detector."
Konechno, eto dovol'no ekzotichnaya ekzotika. No ideya vyglyadit krasivo: obnaruzhit' zerkal'nyi mir s pomosh'yu gradusnika!
