Abstract The Hofstadter butterfly is one of the first and most fascinating examples fractal self-similar quantum nature free electrons in a lattice pierced by perpendicular magnetic field. However, direct experimental verification this effect on single-layer materials still missing as very strong inaccessible fields are necessary. For reason, its indirect has only been realized artificial perio...

We study the persistent current in a system of SU($N$) fermions with repulsive interaction confined ring-shaped potential and pierced by an effective magnetic flux. By applying combination Bethe ansatz numerical analysis, we demonstrate that, as combined effect spin correlations, interactions applied flux specific phenomenon can occur system: spinon creation ground state. As consequence, peculi...

We study a multi-functional device for cold atoms consisting of three-terminal ring circuit pierced by synthetic magnetic flux, where the can be continuous or discretized. The flux controls atomic current through via Aharonov-Bohm effect. Our shows flux-induced transition reflections from an Andreev-like negative density to positive density. Further, direct into specific output ports, realizing...

Fracture at sheared edges upon stretch flanging is a severe problem for ultrahigh-strength steel (UHSS). This study was focused on the improvement of flangeability by heat treatment edge UHSS samples. The materials studied were dual-phase and full martensite steel. samples pierced with 10 mmΦ holes then heat-treated whole-area or partial-area heating. heated tested hole expansion test to determ...

these investigations indicate that the anterior layer of the renal fascia continues across the midline of the body in front of the aorta and inferior vena cava to become continuous with a similar layer on the opposite side of the body. the posterior layer of the renal fascia blends with the fascia covering the psoas major especially at the medial and lateral edges of this muscle. but, in additi...

The dangers of plastic "champagne" corks With the rising cost of cork there are now many types of sparkling wines, such as hock and Moselle, which have a ribbed plastic cork which is securely fastened by a metal band and twisted wire in the conventional way. When these corks are released, however, they are often projected with an extremely high velocity in spite of caution and care on the part ...

Abstract Background Previous discussions regarding variant femoral nerves often report an aberrant slip of a small portion the iliacus muscle as common cause nerve splitting. Within these reported cases, path involves amount and treatment surgical intervention to relieve entrapment. Only few cases have been that were not secondary slippage, none which include discussed below. Case presentation ...

ABSTRACT Turbulent mixing layers (TMLs) are ubiquitous in multiphase gas. They can potentially explain observations of high ions such as O vi, which have significant observed column densities despite short cooling times. Previously, we showed that global mass, momentum, and energy transfer between phases mediated by TMLs is not sensitive to details thermal conduction or numerical resolution. By...

The integration of transition-metal dichalcogenides (TMDs) with non-planar substrates such as nanopillars provides a way to spatially modify the optical properties mainly through localized strain. Similar studies date have utilized insulating SiO 2 nanopillars. Here, we combine monolayer MoS fre...
