Quantum Criticality of Semi-Dirac Fermions in 2+1 Dimensions
Mikolaj D. Uryszek, Elliot Christou, Akbar Jaefari +2
Two-dimensional semi-Dirac fermions are quasiparticles that disperse linearly in one direction and quadratically in the other. We investigate instabilities of semi-Dirac fermions t…
Quasiparticle renormalization in ABC graphene trilayers
Xu Dou, Akbar Jaefari, Yafis Barlas +1
We investigate the effect of electron-electron interactions in ABC stacked graphene trilayers. In the gapless regime, we show that the self-energy corrections lead to the renormali…
Inhomogeneous superconducting phases in the frustrated Kondo-Heisenberg chain
Ariel Dobry, Akbar Jaefari, Eduardo Fradkin
We use bosonization and renormalization group methods to determine the ground state phase diagram of a one-dimensional frustrated Kondo-Heisenberg system consisting of a one-dimens…
Pair-Density-Wave Superconducting Order in Two-Leg Ladders
Akbar Jaefari, Eduardo Fradkin
We show using bosonization methods that extended Hubbard-Heisenberg models on two types of two leg ladders (without flux and with flux per plaquette) have commensurate pair-den…
Boundary effects on the local density of states of one-dimensional Mott insulators and charge density wave states
Dirk Schuricht, Fabian H. L. Essler, Akbar Jaefari +1
We determine the local density of states (LDOS) for spin-gapped one-dimensional charge density wave (CDW) states and Mott insulators in the presence of a hard-wall boundary. We cal…
Charge-Density-Wave and Superconductor Competition in Stripe Phases of High Temperature Superconductors
Akbar Jaefari, Siddhartha Lal, Eduardo Fradkin
We discuss the problem of competition between a superconducting (SC) ordered state with a charge density wave (CDW) state in stripe phases of high superconductors. We conside…
Local density of states of 1D Mott insulators and CDW states with a boundary
Dirk Schuricht, Fabian H. L. Essler, Akbar Jaefari +1
We determine the local density of states (LDOS) of one-dimensional incommensurate charge density wave (CDW) states in the presence of a strong impurity potential, which is modeled…
