A comparative study of multiple-criteria decision-making methods under stochastic inputs [PDF]
, 2016 This paper presents an application and extension of multiple-criteria decision-making (MCDM) methods to account for stochastic input variables. More in particular, a comparative study is carried out among well-known and widely-applied methods in MCDM ...

Dirty Weyl semimetals: Stability, phase transition and quantum criticality
, 2016 We study the stability of three-dimensional incompressible Weyl semimetals in the presence of random quenched charge impurities. Combining numerical analysis and scaling theory we show that in the presence of sufficiently weak randomness (i) Weyl ...

Quantum Multicriticality in Disordered Weyl Semimetal
, 2017 In electronic band structure of solid state material, two band touching points with linear dispersion appear in pair in the momentum space. When they annihilate with each other, the system undergoes a quantum phase transition from three-dimensional Weyl ...

Weak-value amplification for Weyl-point separation in momentum space
New Journal of Physics, 2018 The existence of Weyl nodes in the momentum space is a hallmark of a Weyl semimetal (WSM). A WSM can be confirmed by observing its Fermi arcs with separated Weyl nodes.

Magnetic orders and topological phases from f-d exchange in pyrochlore iridates
, 2012 We study theoretically the effects of f-d magnetic exchange interaction in the R$_2$Ir$_2$O$_7$ pyrochlore iridates. The R$^{3+}$ f-electrons form localized magnetic doublets due to the crystal field environment, while the Ir$^{4+}$ d- electrons are more

Universal optical conductivity of a disordered Weyl semimetal
, 2016 Topological Weyl semimetals, besides manifesting chiral anomaly, can also accommodate a disorder-driven unconventional quantum phase transition into a metallic phase.

Global Phase Diagram of Disordered Type-II Weyl Semimetals [PDF]
, 2017 With electron and hole pockets touching at the Weyl node, type-II Weyl semimetal is a newly proposed topological state distinct from its type-I cousin. We numerically study the localization effect for tilted type-I as well as type-II Weyl semimetals and ...

Comparison of Multi-criteria Decision Making Methods for Selection of Handmade Carpets
Journal of Natural Fibers, 2022 Selecting the best carpet from a set of available alternatives for a particular end-use situation is a difficult job because of association with multiple decision criteria. Three multicriteria decision-making (MCDM) methods, i.e., weighted sum model (WSM)
