Theory of Scanning Tunneling Spectroscopy of Magnetic-Field-Induced Discrete Nodal States in a D-Wave Superconductor
Boldizsar Janko
In the presence of an external magnetic field, the low lying elementary excitations of a d-wave superconductor have quantized energy and their momenta are locked near the node dire…
Incoherent Pair Tunneling as a Probe of the Cuprate Pseudogap
Boldizsar Janko, Ioan Kosztin, K. Levin +2
We argue that incoherent pair tunneling in a cuprate superconductor junction with an optimally doped superconducting and an underdoped normal lead can be used to detect the presenc…
Pairing Fluctuation Theory of Superconducting Properties in Underdoped to Overdoped Cuprates
Qijin Chen, Ioan Kosztin, Boldizsar Janko +1
We propose a theoretical description of the superconducting state of under- to overdoped cuprates, based on the short coherence length of these materials and the associated strong…
On the Relationship Between the Pseudo- and Superconducting Gaps: Effects of Residual Pairing Correlations Below Tc
Ioan Kosztin, Qijin Chen, Boldizsar Janko +1
The existence of a normal state spectral gap in underdoped cuprates raises important questions about the associated superconducting phase. For example, how does this pseudogap evol…
Pairing Correlations and the Pseudo-Gap State: Application of the Pairing Approximation Theory
Jiri Maly, Boldizsar Janko, K. Levin
We investigate the pseudogap onset temperature , the superconducting transition temperature and the general nature of the pseudogap phase using a diagrammatic BCS-Bose E…
Superconducting transitions from the pseudogap state: d-wave symmetry, lattice, and low-dimensional effects
Qijin Chen, Ioan Kosztin, Boldizsar Janko +1
We investigate the behavior of the superconducting transition temperature within a previously developed BCS-Bose Einstein crossover picture. This picture, based on a decoupling sch…
