We introduce a novel technique for improving PA efficiency and coverage of communication links, especially advantageous for the uplink at high frequencies (cm/mm-Waves). The technique is based on a superposition of several DFT-s-OFDM (a.k.a. SC-FDM)

We obtain new fermionic sum representations for the Virasoro characters of the confromal field theory describing the ferromagnetic three-state Potts spin chain. These arise from the fermionic quasi-particle excitations derived from the Bethe equation

We review recent results concerning the representation of conformal field theory characters in terms of fermionic quasi-particle excitations, and describe in detail their construction in the case of the integrable three-state Potts chain. These fermi

By viewing the sine-Gordon and massive Thirring models as perturbed conformal field theories, one sees that they are different (the difference being observable, for instance, in finite-volume energy levels). The UV limit of the former (SGM) is a Gaus

We present fermionic quasi-particle sum representations for some of the characters (or branching functions) of ~${(G^{(1)})_1 \times (G^{(1)})_1 \o (G^{(1)})_2}$ ~for all simply-laced Lie algebras $G$. For given $G$ the characters are written as the

Consider the φ1,3-perturbed minimal unitary conformal field theories M p (with diagonal modular invariant partition function) of central charge c p = 1 − ( 6 p(p + 1) ), p = 3, 4,… It is believed that for one sign of the perturbing parameter the

If a stable particle in a quantum field theory (QFT) is enclosed in a box, its mass changes from its infinite-volume value due to the finite-size depedence of its self-energy (because virtual particles can “travel around a finite-size world”). Ge

We discuss the thermodynamic Bethe ansatz, and explain how it allows one to reduce the infinite-volume thermodynamics of a (1 + 1)-dimensional purely elastic scattering theory to the solution of a set of integral equations for the one-particle excita

We use the thermodynamic Bethe ansatz to find the finite-size corrections to the ground-state energy in an arbitrary (1 + 1)-dimensional purely elastic scattering theory. The leading finite-size effects are characterized by c = c − 12d 0 , where c

The dispersion relations and S-matrix of the one-dimensional Hubbard model at half filling are considered in a certain scaling limit. (In the process we derive a useful small-coupling expansion of the exact lattice dispersion relations.) The resultin
