Algebraic localization of Wannier functions implies Chern triviality in non-periodic insulators
Jianfeng Lu, Kevin D. Stubbs
For gapped periodic systems (insulators), it has been established that the insulator is topologically trivial (i.e., its Chern number is equal to ) if and only if its Fermi proj…
The Iterated Projected Position Algorithm for Constructing Exponentially Localized Generalized Wannier Functions for Periodic and Non-Periodic Insulators in Two Dimensions and Higher
Kevin D. Stubbs, Alexander B. Watson, Jianfeng Lu
Localized bases play an important role in understanding electronic structure. In periodic insulators, a natural choice of localized basis is given by the Wannier functions which de…
Adaptive Procedures for Discrimination Between Arbitrary Tensor-Product Quantum States
Sarah Brandsen, Mengke Lian, Kevin D. Stubbs +2
Discrimination between quantum states is a fundamental task in quantum information theory. Given two arbitrary tensor-product quantum states (TPQS) $ρ_{\pm} = ρ_{\pm}^{(1)} \otimes…
Phase Diagrams of Single Layer Two-Dimensional Transition Metal Dichalcogenides: Landau Theory
Anna N. Morozovska, Eugene A. Eliseev, Kevin D. Stubbs +3
Single layer (SL) two-dimensional transition metal dichalcogenides (TMDs), such as MoS2, ReS2, WSe2, and MoTe2 have now become the focus of intensive fundamental and applied resear…
On discrete Wigner transforms
Zhenning Cai, Jianfeng Lu, Kevin Stubbs
In this work, we derive a discrete analog of the Wigner transform over the space for any prime and any positive integer . We show that the Wigne…
