Quantum oscillations in a biaxial pair density wave state
M. R. Norman, J. C. Seamus Davis
There has been growing speculation that a pair density wave state is a key component of the phenomenology of the pseudogap phase in the cuprates. Recently, direct evidence for such…
Bogoliubov angle and visualization of particle-hole mixture in superconductors
K. Fujita, Ilya Grigorenko, J. Lee +6
Superconducting excitations --Bogoliubov quasiparticles -- are the quantum mechanical mixture of negatively charged electron (-e) and positively charged hole (+e). Depending on the…
Imaging Quasiparticle Interference in Bi2Sr2CaCu2O8+d
J. E. Hoffman, K. McElroy, D. -H. Lee +4
Scanning tunneling spectroscopy of the high-Tc superconductor Bi2Sr2CaCu2O8+d reveals weak, incommensurate, spatial modulations in the tunneling conductance. Images of these energy…
A Four-Unit-Cell Periodic Pattern of Quasiparticle States Surrounding Vortex Cores in Bi2Sr2CaCu2O8+d
J. E. Hoffman, E. W. Hudson, K. M. Lang +4
Scanning tunneling microscopy is used to image the additional quasiparticle states generated by quantized vortices in the high-Tc superconductor Bi2Sr2CaCu2O8+d. They exhibit a Cu-…
Imaging the granular structure of high-Tc superconductivity in underdoped Bi2Sr2CaCu2O8+x
K. M. Lang, V. Madhavan, J. E. Hoffman +4
Granular superconductivity occurs when microscopic superconducting grains are separated by non-superconducting regions through which they communicate by Josephson tunneling to esta…
