Deformation and Stability of Surface States in Dirac semimetals
Mehdi Kargarian, Yuan-Ming Lu, Mohit Randeria
The unusual surface states of topological semimetals have attracted a lot of attention. Recently, we showed [PNAS 113, 8648 (2016)] that for a Dirac semimetal (DSM) arising from ba…
Anomalous low-temperature enhancement of supercurrent in topological-insulator nanoribbon Josephson junctions: evidence for low-energy Andreev bound states
Morteza Kayyalha, Mehdi Kargarian, Aleksandr Kazakov +5
We report anomalous enhancement of the critical current at low temperatures in gate-tunable Josephson junctions made from topological insulator BiSbTeSe nanoribbons with superc…
Infinite Projected Entangled-Pair State algorithm for ruby and triangle-honeycomb lattices
Saeed S. Jahromi, Roman Orus, Mehdi Kargarian +1
The infinite Projected Entangled-Pair State (iPEPS) algorithm is one of the most efficient techniques for studying the ground-state properties of two-dimensional quantum lattice Ha…
