We experimentally investigate the charge (isospin) frustration induced by a geometrical
symmetry in a triangular triple quantum dot. We observe the ground-state charge …

We analyze coherent spin phenomena in triple quantum dots in triangular configuration
under crossed dc and ac magnetic fields. In particular, we discuss the interplay between …

We analyze transport properties of coherent triple-quantum-dot systems in triangular
geometry, weakly coupled to external leads. The real-time diagrammatic technique up to the …

Environmental noise usually hinders the efficiency of charge transport through coherent
quantum systems; an exception is dephasing-assisted transport (DAT). We show that linear …

Abstract The effects of Aharonov–Casher (AC) and He–McKellar–Wilkens (HMW) phases on
entangled spin-1/2 quantum systems are investigated. We use linear charge distributions …

We present an analytical and numerical investigation of the spectral and transport properties
of a quadruple quantum-dot (QQD) structure which is one of the popular low-dimensional …

We consider nanojunctions in the single-electron tunneling regime which, due to a high
degree of spatial symmetry, have a degenerate many-body spectrum. As a consequence …

These lecture notes provide an introduction to the field of quantum transport in interacting
nanojunctions. The theoretical approach to transport considered in the book is based on a …

We report characterizations of two types of Si triple quantum dot (TQD) devices with charge
sensors, with the aim of integrating spin qubits. The QDs of a single TQD device are …

Abstract Aharonov-Bohm (AB) and Aharonov-Casher (AC) effects are treated fully
relativistically in 2+ 1 dimensions. The influences of the relevant geometric and topological …
