The metallic ground state in two-dimensional (2D) superconductors has attracted much attention but is still under intense scrutiny. Especially, the measurements ultralow temperature region are challenging for 2D due to sensitivity external perturbations. In this work, resistance saturation induced by noise, named as "extrinsic anomalous state", observed transition metal dichalcogenide (TMD) superconductor 4Ha-TaSe2 nanodevices. However, with further decreasing temperature, credible evidence...
Abstract Quantum information can be coded by the topologically protected edges of fractional quantum Hall (FQH) states. Investigation on FQH in hope searching and utilizing non-Abelian statistics has been a focused challenge for years. Manipulating edges, e.g. to bring close each other or separate spatially, is common essential step such studies. The edge structures confined region are typically presupposed same as that open analysis experimental results, but whether they remain unchanged...
The recent discovery of superconducting interfaces in the $KTaO_3 (111)$-based heterostructures is intriguing, since a much higher critical temperature (TC ~ 2 K) achieved compared to that $SrTiO_3$ (~ 300 mK). In this paper, we report properties $EuO/KTaO_3 (111)$ interface as function carrier density ($n_s$). maximum T_C observed be K at $n_s$ $1\times10^{14}$ cm-2. addition, show current and upper magnetic field can effectively tuned by back gate voltage. Interestingly, dependence...
A two-dimensional system with extra degrees of freedom, such as spin and valley, is great interest in the study quantum phase transitions. The critical condition when a transition between different multicomponent fractional Hall states appears one very few junctions for many-body problems theoretical calculations experiments. In this work, we present that uniaxial strain induces pseudospin transitions composite fermions hole gas. Determined from transport behavior, along ⟨111⟩ effectively...
A temperature below 100 µK is achieved in a customized cryogen-free dilution refrigerator with copper-nuclear demagnetization stage. The lowest of conduction electrons the stage as measured by using pulsed platinum nuclear magnetic resonance thermometer, and can remain for over 10 h. field up to 9 T research 12 be controlled independently, provided coaxial room-temperature-bore magnet.
Target-driven visual navigation is a widely focused learning-based approach in the field of computer vision. However, it faces two major challenges: poor generalization ability to unknown scenes, and performance for increased number scenes. In this paper, an end-to-end target-driven method, which uses Spatial Semantic Information (SSI) navigate agent target, presented. To fully integrate spatial semantic information scene, encoded into 8-D context vector. addition, size detected bounding box...
In this paper, we consider a disruption tolerant network (DTN) which enables data transmission with intermittent connectivity and in instantaneous end-to-end path between source destination may not exist. We explore routing problems such networks consideration of limited storage for each intermediate node. A graph model called the enhanced time-varying (STVG) is presented, fits dynamic topology characteristics time- varying parameters DTN. transform nodes finite buffer DTN into links...
