# Landau-Bogolubov Energy Spectrum of Superconductors

## TL;DR

This paper reveals that the energy spectrum of superconductors mirrors that of superfluid helium, suggesting superconductivity is fundamentally similar to superfluidity but involving charged particles.

## Contribution

It demonstrates the equivalence of the elementary excitation spectrum in superconductors and superfluid helium, linking superconductivity to superfluidity for charged particles.

## Key findings

- Dispersion relation in superconductors matches that in superfluid helium.
- Superconductivity is analogous to superfluidity for charged particles.
- Energy spectrum of elementary excitations is identical in both systems.

## Abstract

We demonstrate that a dispersion relation of elementary excitations in the Fermi liquid as a superconductor is identical to the one in a quantum liquid HeII. Hence, we show that the superconductivity is, in fact, the same as superfluidity, but for charged particles.
