Green's Function Methods for Computing Supercurrents in Josephson Junctions
Eduardo R. Mucciolo, Jouko Nieminen, Xiao Xiao +3
Interest in Josephson junctions (JJs) has increased rapidly in recent years not only because of their use in qubits and other quantum devices but also due to the unique physics sup…
Probing the semiconductor-to-dirac semimetal transition in Na-Sb-Bi alloys with x-ray Compton scattering
Aki Pulkkinen, Veenavee Nipunika Kothalawala, Kosuke Suzuki +12
We discuss electron redistribution during the semiconductor-to-Dirac semimetal transition in Na-Sb-Bi alloys using x-ray Compton scattering experiments combined with first-principl…
Interlayer Charge-density-wave Vector Phase Induced Structural Chirality
Sen Shao, Wei-Chi Chiu, Tao Hou +21
Chiral charge density waves (CDWs) have attracted intense interest due to their exotic quantum properties, yet the microscopic origin of structural chirality emerging from correlat…
Recycling failed photoelectrons via tertiary photoemission
M. Matzelle, Wei-Chi Chiu, Caiyun Hong +8
A key insight of Einstein's theory of the photoelectric effect is that a minimum energy is required for photoexcited electrons to escape from a material. For the past century it ha…
Atomistic modeling of a superconductor-transition-metal dichalcogenide-superconductor Josephson junction
Jouko Nieminen, Sayandip Dhara, Wei-Chi Chiu +2
Using an atomistic tight-binding model, we study the characteristics of a Josephson junction formed by monolayers of MoS sandwiched between Pb superconducting electrodes. We de…
Band structures and invariants of two-dimensional transition metal dichalcogenide monolayers from fully-relativistic Dirac-Kohn-Sham theory using Gaussian-type orbitals
Marius Kadek, Baokai Wang, Marc Joosten +5
Two-dimensional (2D) materials exhibit a wide range of remarkable phenomena, many of which owe their existence to the relativistic spin-orbit coupling (SOC) effects. To understand…
Relativistic horizon of interacting Weyl fermions in condensed matter systems
Wei-Chi Chiu, Guoqing Chang, Gennevieve Macam +12
The intersections of topology, geometry and strong correlations offer many opportunities for exotic quantum phases to emerge in condensed matter systems. Weyl fermions, in particul…
Strain-Induced Charge Density Waves with Emergent Topological States in Monolayer NbSe2
Wei-Chi Chiu, Sougata Mardanya, Robert Markiewicz +7
Emergence of topological states in strongly correlated systems, particularly two-dimensional (2D) transition-metal dichalcogenides, offers a platform for manipulating electronic pr…
Non-orthogonal Spin-Momentum Locking
T. Hakioglu, Wei-Chi Chiu, R. S. Markiewicz +2
Spin-momentum locking is a unique intrinsic feature of strongly spin-orbit coupled materials and a key to their promise of applications in spintronics and quantum computation. Much…
Topological Dirac Semimetal Phase in Bismuth Based Anode Materials for Sodium-Ion Batteries
Wei-Chi Chiu, Bahadur Singh, Sougata Mardanya +7
Bismuth has recently attracted interest in connection with Na-ion battery anodes due to its high volumetric capacity. It reacts with Na to form NaBi which is a prototypical Dir…
A new noncollinear ferromagnetic Weyl semimetal with anisotropic anomalous Hall effect
Hung-Yu Yang, Bahadur Singh, Jonathan Gaudet +18
A developing frontier in condensed matter physics is the emergence of novel electromagnetic responses, such as topological and anomalous Hall effect (AHE), in ferromagnetic Weyl se…
