Comment on Multiple Quantum Oscillations in the de Haas - van Alphen Spectra of the Underdoped High-Temperature Superconductor YBa2Cu3O6.5 (A. Audouard et al., Phys. Rev. Lett. 103 (2009) 157003)
A. S. Alexandrov, I. O. Thomas
Recent observations of slow magneto-oscillations in some underdoped cuprate superconductors are one of the most striking discoveries in the field of superconductivity since many pr…
Zero-temperature phase transitions in dilute bosonic superfluids on a lattice
A. S. Alexandrov, I. O. Thomas
Kinetic energy driven phase transitions in Bose superfluids occur at low values of the repulsion when the values of the next-to-nearest and next-to-next-to-nearest hopping term att…
Kinetic quantum phase transition in bosonic superfluids on a lattice
A. S. Alexandrov, I. O. Thomas
It has been well known that quantum fluctuations induce a macroscopic phase transition from a superfluid to a Mott insulator phase driven by the repulsive potential energy in the g…
Singlet and triplet bipolarons on the triangular lattice
J. P. Hague, P. E. Kornilovitch, J. H. Samson +1
We study the Coulomb-Fröhlich model on a triangular lattice, looking in particular at states with angular momentum. We examine a simplified model of crab bipolarons with angular mo…
