Many-body correlations and macroscopic quantum behaviours are fascinating condensed
matter problems. A powerful test-bed for the many-body concepts and methods is the Kondo …

Tuning a material to the cusp between two distinct ground states can produce physical
properties that are unlike those in either of the neighbouring phases. Advances in the …

Quantum mechanics and Coulomb interaction dictate the behaviour of small circuits. The
thermal implications cover fundamental topics from quantum control of heat to quantum …

One remarkable feature of strongly correlated systems is the phenomenon of
fractionalization where quasiparticles carry only a fraction of the charge or spin of the …

Half a century after its discovery, the Josephson junction has become the most important
nonlinear quantum electronic component at our disposal. It has helped reshape the …

In one-dimensional conductors, interactions result in correlated electronic systems. At low
energy, a hallmark signature of the so-called Tomonaga–Luttinger liquids is the universal …

When assembling individual quantum components into a mesoscopic circuit, the interplay
between Coulomb interaction and charge granularity breaks down the classical laws of …

Quantum physics emerge and develop as temperature is reduced. Although mesoscopic
electrical circuits constitute an outstanding platform to explore quantum behaviour, the …

The Tomonaga-Luttinger liquid (TLL) concept is believed to generically describe the strongly
correlated physics of one-dimensional systems at low temperatures. A hallmark signature in …

We review the intriguing many-body physics resulting out of the interplay of a single, local
impurity and the two-particle interaction in a one-dimensional Fermi system. Even if the …
