Üçgen Optik Örgüde Kuantum Spin Hall Etkisi için Sıkı-Bağ Modeli

ÖzBu makelede, üçgen örgü üzerinde kuantum spin Hall sistemi için bir sıkı-bağ modeli önermekte ve Z2topolojik yalıtkanının ayırt edici özelliği olan boşluk geçiş durumlarını da içeren kenar durum spektrumunuincelemekteyiz. Bu sistemin avantajı, serbest elektron sınırı B. Beri ve N. R. Cooper tarafından verilen (Phys.Rev. Lett. 107, 145301, 2011) fermiyonik aşırı soğuk atomik sistemlerde de incelenme imkanının olmasıdır.
