Not only are they super creamy, but they couldn’t be easier to use. Enter the beauty of a good contour stick. Then blend, blend, blend before adding foundation and highlighter to balance things out.Īnd when it comes to choosing a contouring product? Keep in mind that creams will always be more blendable than powders, a good option if you’re a beginner or are looking for a more natural result. You’ll want to apply it in a few strategic spots: along your temples, under the cheekbones, along your jawline, and down the sides of your nose. In order to do so, your contouring product should be two shades deeper than your foundation. The secret to mastering the move? The end goal is for it to truly be undetectable, and for everyone to think that you were simply born with a bone structure that’s just that good. Thanks to a massive influx of new contouring products, not to mention the impact of a certain mega-famous, contour-loving Hollywood family, contouring is now more commonplace than ever before.

That’s most definitely not the case anymore. All graphs are drawn in the first Brillouin zone with interaction u = 1 and the parameters (a) B = 0, μ = − 0.6619, density n = 0.9801 (near half-filled band), (b) B = 0, μ = − 3.8508, density n = 0.1389 (dilute limit), (c) B = 0.555, μ = − 1, and (d) B = 0.555, μ = − 1.32.Once upon a time, not so long ago, the art of contouring-using shadows and darker colors to define and reshape your face-was a makeup technique almost solely reserved for the pros. (d) Gapped excitation spectra for length-1 k − Λ string and a length-2 Λ string. (c) Fractional antiholon-spinon excitations ( 1 2, − 1 2 ), i.e., adding an extra spin-down electron to create an antiholon and a spinon. The inset in (a) shows the excitation for small momentum, while the inset in (b) shows the excitation for the momentum within the first Brillouin zone, whose zero energy modes are situated at 0, 2 π n c, 2 π ( 1 − n c ), 2 π. The orange areas in (a) and (b) represent particle-hole excitations of charge, whereas the green parts show the two-spinon excitations with quantum numbers ( Δ η z, Δ S z ) = ( 0, 1 ) induced from spin flipping. As an application of these concepts, which hold true for higher-dimensional systems, we propose a quantum cooling scheme based on the interaction-driven refrigeration cycle.Įlementary fractional spin and charge excitations. (2) We study the interaction-driven phase transition and the associated criticality, and build up an essential connection between the contact susceptibilities and the variations of density, magnetization, and entropy with respect to the interaction strength. We investigate the universal properties and the asymptotic of correlation functions of the SILL. (1) We calculate the fractional excitations of the system in various phases, from which we identify the parameter regime featuring the spin-incoherent Luttinger liquid (SILL).


In this work, based on the solutions to the thermodynamic Bethe ansatz equations, we provide a rigorous study on the following. Although the one-dimensional repulsive Fermi-Hubbard model has been intensively studied over many decades, a rigorous understanding of many aspects of the model is still lacking.
