Microstructural and compositional design principles for Mo-V-Nb-Ti-Zr multi-principal element alloys: a high-throughput first-principles study
Zhidong Leong, Upadrasta Ramamurty, Teck Leong Tan
Due to the vast compositional space of multi-principal element alloys (MPEAs), the rational design of MPEAs for optimized microstructures is difficult. Therefore, a high-throughput…
Robust cluster expansion of multicomponent systems using structured sparsity
Zhidong Leong, Teck Leong Tan
Identifying a suitable set of descriptors for modeling physical systems often utilizes either deep physical insights or statistical methods such as compressed sensing. In statistic…
Scale-invariance as the cause of the superconducting dome in the cuprates
Zhidong Leong, Kridsanaphong Limtragool, Chandan Setty +1
Recent photoemission spectroscopy measurements (T. J. Reber et al., arXiv:1509.01611) of cuprate superconductors have inferred that the self-energy exhibits critical scaling over a…
Absence of Luttinger's theorem for fermions with power-law Green functions
Kridsanaphong Limtragool, Zhidong Leong, Philip W. Phillips
We investigate the validity of Luttinger's theorem (or Luttinger sum rule) in two scale-invariant fermionic models. We find that, in general, Luttinger's theorem does not hold in a…
Power-law liquid in cuprate superconductors from fermionic unparticles
Zhidong Leong, Chandan Setty, Kridsanaphong Limtragool +1
Recent photoemission spectroscopy measurements [arXiv:1509.01611] on cuprate superconductors have inferred that over a wide range of doping, the imaginary part of the electron self…
Absence of nematic ordering transition in a diamond lattice: Application to
Chandan Setty, Zhidong Leong, Shuyi Zhang +1
Recent neutron scattering observations by Plumb et al. [1] reveal that the ground state of is magnetic with two distinct Fe environments, instead of a quantum spin liqu…
Realizing infrared power-law liquids in the cuprates from unparticle interactions
Kridsanaphong Limtragool, Chandan Setty, Zhidong Leong +1
Recent photoemission experiments \cite{dessau} reveal that the excitations along the nodal region in the strange metal of the cuprates, rather than corresponding to poles in the si…
The effects of Coulomb interactions on the superconducting gaps in iron-based superconductors
Zhidong Leong, Philip Phillips
Recent angle-resolved photoemission spectroscopy measurements of Co-doped LiFeAs report a large and robust superconducting gap on the -centered hole band that lies 8 meV below t…
High-Energy Damping by Particle-Hole Excitations in the Spin-Wave Spectrum of Iron-Based Superconductors
Zhidong Leong, Wei-Cheng Lee, Weicheng Lv +1
Using a degenerate double-exchange model, we investigate the spin excitation spectra of iron pnictides. The model consists of local spin moments on each Fe site, as well as itinera…
