We discuss melting of a Wigner crystal formed on a free surface of superfluid $$^4$$ He, in quasi-one-dimensional (Q1D) channels of width between 5 and 15 $$\upmu $$ m. We reexamine our previous transport data (Ikegami et al. in Phys Rev B 82:201104(

We measured electron transport state spectra of an In0.05Ga0.95As vertical double quantum dot. Both the ground and excited states of transport spectra from two electrons to three electrons are measured using a large source–drain voltage. In the obt

We have investigated the finite size effect on the Wigner solid transition of the electrons trapped on the liquid 4He surface by the mobility measurement of the electrons confined in a 15 μm-wide channel. The resistance above the Wigner solid transi

We report on the experimental study of the resonance microwave absorption of surface-state electrons (SSE) on liquid 3He. The absorption is detected as a variation of the microwave power passing through the experimental cell, or as a resonance-induce

We report on our analysis of the melting process of highly magnetized solid 3 He. Akimoto et al. found that the solid-liquid interface becomes unstable during melting in a magnetic field of 9 T. The liquid then penetrates into the solid in the form o

We developed a cryostat for optical observations at ultralow temperatures and in strong magnetic fields. The optical system consisted of a LED, a light transmission path and a CCD chip, with all components installed inside the inner vacuum can of the

We elucidate the melting process of highly magnetized solid 3He by observing the magnetization profile and the liquid-solid interface simultaneously. Clear enhancements of magnetization and magnetization gradients at the interface of both the solid a

A melting instability has been observed during rapid melting of highly magnetized solid ${}^{3}\mathrm{He}$. The instability occurred only if the solid is grown at low initial temperature and in high magnetic field, i.e., with high magnetization, and

We present preliminary results of growth and melting at the interface between spin ordered solid 3 He and superfluid liquid 3 He both in a low magnetic field of 0.2 T and in a high magnetic field of 8.9 T. Measurements of the growth and melting veloc
