Competing orders in the Dirac-like electronic structure and the non-linear sigma model with the topological terms
Pouyan Ghaemi, Shinsei Ryu
The Dirac-like electronic structure can host a large number of competing orders in the form of mass terms. In particular, two different order parameters can be said to be dual to e…
Majorana modes at the ends of superconductor vortices in doped topological insulators
Pavan Hosur, Pouyan Ghaemi, Roger S. K. Mong +1
Recent experiments have observed bulk superconductivity in doped topological insulators. Here we ask whether vortex Majorana zero modes, previously predicted to occur when supercon…
Anomalous Zeeman response in coexisting phase of superconductivity and spin-density wave as a probe of extended -wave pairing structure in ferro-pnictide
Pouyan Ghaemi, Ashvin Vishwanath
In several members of the ferro-pnictides, spin density wave (SDW) order coexists with superconductivity over a range of dopings. In this letter we study the anomalous magnetic Zee…
In-plane transport and enhanced thermoelectric performance in thin films of the topological insulators Bi_2Te_3 and Bi_2Se_3
Pouyan Ghaemi, Roger Mong, Joel E. Moore
Several small-bandgap semiconductors are now known to have protected metallic surface states as a consequence of the topology of the bulk electron wavefunctions. The known "topolog…
