Potential Coexistence of Exciton and Fermion Pair Condensations
LeeAnn M. Sager, Shiva Safaei, David A. Mazziotti
Extensive theoretical and experimental investigation has been conducted on fermion pair condensation and exciton condensation as distinct classes of Bose-Einstein-like condensation…
Quantum signature of exciton condensation
Shiva Safaei, David A. Mazziotti
Exciton condensation, a Bose-Einstein-like condensation of excitons, was recently reported in an electronic double layer (EDL) of graphene. We show that a universal quantum signatu…
Quantum spin Hall effect in strained (111)-oriented SnSe layers
Shiva Safaei, Marta Galicka, Perla Kacman +1
Recently, the quantum spin Hall effect has been predicted in (111)-oriented thin films of SnSe and SnTe topological crystalline insulators. It was shown that in these films the ene…
Quantum Spin Hall Effect in IV-VI Topological Crystalline Insulators
Shiva Safaei, Marta Galicka, Perla Kacman +1
We envision that quantum spin Hall effect should be observed in -oriented thin films of SnSe and SnTe topological crystalline insulators. Using a tight-binding approach supp…
Observation of topological crystalline insulator surface states on (111)-oriented PbSnSe films
C. M. Polley, P. Dziawa, A. Reszka +13
We present angle resolved photoemission spectroscopy measurements of the surface states on in-situ grown (111) oriented films of PbSnSe, a three dimensional topologic…
The topological-crystalline-insulator (Pb,Sn)Te - surface states and their spin-polarization
S. Safaei, P. Kacman, R. Buczko
Using a tight-binding approach we study theoretically the nature of surface states in Pb0.4Sn0.6Te - the newly discovered topological-crystalline-insulator. Apart from the studied…
Spin-polarized (001) surface states of the topological crystalline insulator Pb_{0.73}Sn_{0.27}Se
B. M. Wojek, R. Buczko, S. Safaei +9
We study the nature of (001) surface states in Pb_{0.73}Sn_{0.27}Se in the newly discovered topological-crystalline-insulator (TCI) phase as well as the corresponding topologically…
