A novel artificial condensed matter lattice and a new platform for one-dimensional topological phases
Ilya Belopolski, Su-Yang Xu, Nikesh Koirala +22
Engineered lattices in condensed matter physics, such as cold atom optical lattices or photonic crystals, can have fundamentally different properties from naturally-occurring elect…
A new form of (unexpected) Dirac fermions in the strongly-correlated cerium monopnictides
Nasser Alidoust, A. Alexandradinata, Su-Yang Xu +14
Discovering Dirac fermions with novel properties has become an important front in condensed matter and materials sciences. Here, we report the observation of unusual Dirac fermion…
Experimental Observation of Two Massless Dirac-Fermion Gases in Graphene-Topological Insulator Heterostructure
Guang Bian, Ting-Fung Chung, Chang Liu +19
Graphene and topological insulators (TI) possess two-dimensional Dirac fermions with distinct physical properties. Integrating these two Dirac materials in a single device creates…
Gigantic surface life-time of an intrinsic topological insulator revealed via time-resolved (pump-probe) ARPES
Madhab Neupane, Su-Yang Xu, Yukiaki Ishida +11
The interaction between light and novel two-dimensional electronic states holds promise to realize new fundamental physics and optical devices. Here, we use pump-probe photoemissio…
Topological Nodal-Line Fermions in the Non-Centrosymmetric Superconductor Compound PbTaSe2
Guang Bian, Tay-Rong Chang, Raman Sankar +18
We report the identification of a Topological Nodal-Line Semimetal state in PbTaSe2.
Unconventional transformation of spin Dirac phase across a topological quantum phase transition
Su-Yang Xu, Madhab Neupane, Ilya Belopolski +15
The topology of a topological material can be encoded in its surface states. These surface states can only be removed by a bulk topological quantum phase transition into a trivial…
