The properties of quasi-two-dimensional semiconductor quantum dots are reviewed.
Experimental techniques for measuring the electronic shell structure and the effect of …

This paper gives a systematic review of a field theoretical approach to the fractional quantum
Hall effect (FQHE) that has been developed in the past few years. We first illustrate some …

Topological solitons, a class of stable nonlinear excitations, appear in diverse domains as in
the Skyrme model of nuclear forces. Here, we argue that similar excitations play an …

Applications of conformal field theory to the theory of fractional quantum Hall systems are
discussed. In particular, Laughlin's wave function and its cousins are interpreted as …

We analyze pairing of fermions in two dimensions for fully gapped cases with broken parity
(P) and time reversal (T), especially cases in which the gap function is an orbital angular …

We study the two-dimensional electron gas in a high magnetic field at filling factor ν= 1 for an
arbitrary ratio of the Zeeman energy g μ BB to the typical interaction energy. We find that the …

At strong magnetic fields, double-layer two-dimensional electron-gas systems can form an
unusual broken-symmetry state with spontaneous interlayer phase coherence. In this paper …

The phenomenon of Bose–Einstein condensation is a phase transition originally predicted
by Bose and Einstein in 1924. In particular, it was shown that below a critical temperature T …

Recent experiments on twisted bilayer graphene have shown a high-temperature parent
state with massless Dirac fermions and broken electronic flavor symmetry; superconductivity …

Kalmeyer-Laughlin (KL) chiral spin liquid (CSL) is a type of quantum spin liquid without time-
reversal symmetry, and it is considered as the parent state of an exotic type of …
