Tunneling conductance of long-range Coulomb interacting Luttinger liquid
DinhDuy Vu, Anibal Iucci, Sankar Das Sarma
The theoretical model of the short-range interacting Luttinger liquid predicts a power-law scaling of the density of states and the momentum distribution function around the Fermi…
Spontaneous symmetry breaking in a honeycomb lattice subject to a periodic potential
Robert E. Throckmorton, S. Das Sarma
Motivated by recent developments in twisted bilayer graphene moiré superlattices, we investigate the effects of electron-electron interactions in a honeycomb lattice with an applie…
Möbius Insulator and Higher-Order Topology in MnBiTe
Rui-Xing Zhang, Fengcheng Wu, S. Das Sarma
We propose MnBiTe as a magnetically tunable platform for realizing various symmetry-protected higher-order topology. Its canted antiferromagnetic phase can host exo…
Physical mechanisms for zero-bias conductance peaks in Majorana nanowires
Haining Pan, S. Das Sarma
Motivated by the need to understand and simulate the ubiquitous experimentally-observed zero-bias conductance peaks in superconductor-semiconductor hybrid structures, we theoretica…
Nonmonotonic plasmon dispersion in strongly interacting Coulomb Luttinger liquids
Yang-Zhi Chou, Sankar Das Sarma
We demonstrate that the plasmon in one-dimensional Coulomb interacting electron fluids can develop a finite-momentum maxon-roton-like nonmonotonic energy-momentum dispersion. Such…
Higher-Order Topological Dirac Superconductors
Rui-Xing Zhang, Yi-Ting Hsu, S. Das Sarma
We introduce higher-order topological Dirac superconductor (HOTDSC) as a new gapless topological phase of matter in three dimensions, which extends the notion of Dirac phase to a h…
