Aspects of Holographic Superconductivity [PDF]
, 2012 In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices
Advanced Materials, EarlyView.We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

Carrier distribution in multi-band materials and its effect on thermoelectric properties
Journal of Materiomics, 2016 Band convergence is one of the most interesting topics in recent studies of thermoelectrics. However, its effect on thermoelectric properties is only simply stated as improving band degeneracy.

Unconventional superconductivity [PDF]
Advances in Physics, 2017 Conventional superconductivity, as used in this review, refers to electron-phonon coupled superconducting electron-pairs described by BCS theory. Unconventional superconductivity refers to superconductors where the Cooper pairs are not bound together by phonon exchange but instead by exchange of some other kind, e. g.

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures
Advanced Materials, EarlyView.A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Applied Sciences, 2018 Metal nanoparticles are extensively studied due to their unique chemical and physical properties, which differ from the properties of their respective bulk materials. Likewise, the properties of heterogeneous bimetallic structures are far more attractive

Gate‐Induced Critical Current Modulation in W–C Nanowires: The Role of Fabrication
Advanced Materials Technologies, EarlyView.Focused ion beam induced deposition (FIBID) enables precise control of superconducting W–C nanowire devices. Introducing a Ga+ focused ion beam (FIB) cleaning step reduces substrate damage and suppresses leakage currents, shifting gating thresholds to higher voltages.

Advanced Science, EarlyView.This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Fabrication of superconducting nanowires from ultrathin MgB2 films via focused ion beam milling
AIP Advances, 2015 High quality superconducting nanowires were fabricated from ultrathin MgB2 films by a focused ion beam milling technique. The precursor MgB2 films in 10 nm thick were grown on MgO substrates by using a hybrid physical-chemical vapor deposition method ...

Gutzwiller-RVB theory of high temperature superconductivity : results from renormalized mean field theory and variational Monte Carlo calculations [PDF]
, 2007 We consider the theory of high temperature superconductivity from the viewpoint of a strongly correlated electron system. In particular, we discuss Gutzwiller projected wave functions, which incorporate strong correlations by prohibiting double occupancy
