Analytic conformal bootstrap and Virasoro primary fields in the Ashkin-Teller model
Nikita Nemkov, Sylvain Ribault
We revisit the critical two-dimensional Ashkin-Teller model, i.e. the orbifold of the compactified free boson CFT at . We solve the model on the plane by comput…
Liouville perturbation theory for Laughlin state and Coulomb gas
Nikita Nemkov, Semyon Klevtsov
We consider the generating functional (logarithm of the normalization factor) of the Laughlin state on a sphere, in the limit of a large number of particles . The problem is ref…
Equivalent sources approach for non radiating states and anapole metamaterials
Giuseppe Labate, Anar K. Ospanova, Nikita A. Nemkov +2
In this work, we discuss theoretical findings on the common feature describing nonradiating sources, based on equivalent sources from which it is possible to derive cloaking device…
Electromagnetic sources beyond common multipoles
Nikita A. Nemkov, Alexey A. Basharin, Vassily A. Fedotov
The complete dynamic multipole expansion of electromagnetic sources contains more types of multipole terms than it is conventionally perceived. The toroidal multipoles are one of t…
