Effective Time Reversal Symmetry Breaking and Energy Spectra of Graphene Armchair Rings
Tianhuan Luo, A. P. Iyengar, H. A. Fertig +1
We study the energy spectra and wavefunctions of graphene rings formed from metallic armchair ribbons, near zero energy, to search for properties which may be identified with "effe…
Phase diagram for quantum Hall states in graphene
Jianhui Wang, A. Iyengar, H. A. Fertig +1
We investigate integer and half-integer filling states (uniform and unidimensional stripe states respectively) for graphene using the Hartree-Fock approximation. For fixed filling…
Conductance Through Graphene Bends and Polygons
A. Iyengar, T. Luo, H. A. Fertig +1
We investigate the transmission of electrons between conducting nanoribbon leads oriented at multiples of 60 degrees with respect to one another, connected either directly or throu…
4D-XY quantum criticality in a doped Mott insulator
M. Franz, A. P. Iyengar
A new phenomenology is proposed for the superfluid density of strongly underdoped cuprate superconductors based on recent data for ultra-clean single crystals of YBCO. The data fea…
Exact summation of vertex corrections to the penetration depth in d-wave superconductors
A. Iyengar, M. Franz
A variety of experiments suggest that in the cuprates, the low-energy superconducting quasiparticles undergo forward scattering from extended impurity potentials. We argue that whe…
The pseudogap state in superconductors: Extended Hartree approach to time-dependent Ginzburg-Landau Theory
Jelena Stajic, Andrew Iyengar, Qijin Chen +1
It is well known that conventional pairing fluctuation theory at the Hartree level leads to a normal state pseudogap in the fermionic spectrum. Our goal is to extend this Hartree a…
