“…Similar behavior has been observed with 3 He atoms on a carbon nanotube. 31 The increase in strain is also corroborated in the shift of the minimum of the re-entrant looking f m (V g ) curve 32 under the influence of neon. The re-entrant W-shape indicates a crossover from the built-in-tension-dominated behavior to gate-induced-tension dependence, the position of which moves to larger V g with enhanced initial tension.…”

Low-frequency 1 f γ noise is ubiquitous, even in high-end electronic devices. For qubits such noise results in decrease of their coherence times. Recently, it was found that adsorbed O 2 molecules provide the dominant contribution to flux noise in superconducting quantum interference devices. To clarify the basic principles of such adsorbant noise, we have investigated the formation of low-frequency noise while the mobility of surface adsorbants is varied by temperature. In our experiments, we measured low-frequency current noise in suspended monolayer graphene samples under the influence of adsorbed Ne atoms. Owing to the extremely small intrinsic noise of

“…It is also exciting to think that 3 He can be used instead of 4 He, which would lead to an effective fermionic model. [51] It is well known that the VDW potentials for 3 He are quite similar to the bosonic 4 He, while 3 He also tends to exhibit rich physics related to its spin and orbital degrees of freedom (such as anisotropic superfluidity, nontrivial topological defects and textures, etc.).

Atoms deposited on 2D electronic materials, such as graphene, can exhibit unconventional many‐body correlations, not accessible in other settings. All of these are driven by van der Waals forces: between the atoms themselves and atom‐material interactions. For example 4He atoms on 2D materials can potentially form a variety of exotic quantum states of matter, such as 2D supersolids and superfluids, in addition to solid phases. For the “most quantum” case of a single helium layer we discuss, from a theoretical perspective, how the effective low‐energy (Bose–Hubbard) description can take advantage of the extreme sensitivity of this unique system to the interplay between the atomic (helium) and solid‐state (graphene) components. Due to the extraordinary variety and tunability of 2D electronic materials, it is envisaged that a wide range of correlated atomic phases can be realized under favorable conditions. Exciting possibilities in the opposite extreme of many atomic layers forming a liquid on top of graphene are also outlined —in this case a so‐called “spinodal dewetting” pattern can form at the liquid–vapor interface which reflects the presence and electronic properties of graphene underneath. Such patterns could be manipulated by choosing different atoms and materials, with potential technological applications.
