Parity-independent Kondo effect of correlated electrons in electrostatically defined ZnO quantum dots.
Nat Commun

Research Institute of Electrical Communication, Tohoku University, Sendai, Japan.
Quantum devices such as spin qubits have been extensively investigated in electrostatically confined quantum dots using high-quality semiconductor heterostructures like GaAs and Si. Here, we present a demonstration of electrostatically forming the quantum dots in ZnO heterostructures. Through the transport measurement, we uncover the distinctive signature of the Kondo effect independent of the even-odd electron number parity, which contrasts with the typical behavior of the Kondo effect in GaAs.

The reactivity of Bi clusters ( = 2 to 30) with O is found to display even-odd alternations. The open-shell even-sized Bi clusters are more reactive than the closed-shell odd-sized clusters, except Bi, which exhibits no observable reactivity toward O. We have investigated the structure and bonding of Bi to understand its remarkable resistance to oxidation.

Article Synopsis
- The study explores how the quantum size effect influences the electronic and phononic properties of ultra-thin metal films, particularly focusing on their specific heat.
- It demonstrates that the specific heat behavior varies significantly with the film thickness due to the quantum confinement of electrons and phonons, leading to unique standing wave modes.
- The research emphasizes the importance of considering the thickness-dependent Fermi wavelength in ultra-thin films, which could impact fundamental physics research and thermodynamic device applications.
Electrically Controlled Anomalous Hall Effect and Orbital Magnetization in Topological Magnet MnBi_{2}Te_{4}.

Department of Physics, The Pennsylvania State University, University Park, Pennsylvania 16802, USA.
We propose an intrinsic mechanism to understand the even-odd effect, namely, opposite signs of anomalous Hall resistance and different shapes of hysteresis loops for even and odd septuple layers (SLs), of MBE-grown MnBi_{2}Te_{4} thin films with electron doping. The nonzero hysteresis loops in the anomalous Hall effect and magnetic circular dichroism for even-SLs MnBi_{2}Te_{4} films originate from two different antiferromagnetic (AFM) configurations with different zeroth Landau level energies of surface states. The complex form of the anomalous Hall hysteresis loop can be understood from two magnetic transitions, a transition between two AFM states followed by a second transition to the ferromagnetic state.
