作者精确地计算了电子之间的哈伯德相互作用的情况下，在磁场中的环上的电子的光谱。他们发现，当通过环的通量发生变化时，会发生非常不寻常的共振。这些共振的出现强烈地依赖于电子的总数N。它们出现在通量变化Δ f=1/N时。与两粒子束缚态类似，人们可以认为在电子之间具有强相互作用的环上，N粒子束缚态出现。这样的共振可以在芳香族分子中发现，并且在“库仑阻塞”条件下在单个连接的量子点的环系统上发现。
The authors have calculated exactly the spectrum of electrons on a ring in a magnetic field for the case of the Hubbard interaction between electrons. They have found that very unusual resonances occur when the flux through the ring changes. The appearance of these resonances strongly depends on the total number of electrons N. They appear when the flux changes by Delta f=1/N. In analogy with two-particle bound states one can think that on a ring with strong interactions between electrons, N-particle bound states appear. Such resonances may be found in aromatic molecules and on a ring system of singly connected quantum dots for 'Coulomb blockade' conditions.
