Influence of subunit structure on the oligomerization state of light harvesting complexes: a free energy calculation study
Lorant Janosi, Harindar Keer, Ioan Kosztin +1
Light harvesting complexes 2 (LH2) from Rhodospirillum (Rs.) molischianum and Rhodopseudomonas (Rps.) acidophila form ring complexes out of eight or nine identical subunits, respec…
Fluctuation-Driven Molecular Transport in an Asymmetric Membrane Channel
Ioan Kosztin, Klaus Schulten
Channel proteins, that selectively conduct molecules across cell membranes, often exhibit an asymmetric structure. By means of a stochastic model, we argue that channel asymmetry i…
Origin of the pseudogap phase: Precursor superconductivity versus a competing energy gap scenario
K. Levin, Qijin Chen, Ioan Kosztin +3
In the last few years evidence has been accumulating that there are a multiplicity of energy scales which characterize superconductivity in the underdoped cuprates. In contrast to…
Short Coherence Length Superconductivity: A Generalization of BCS Theory for the Underdoped Cuprates
K. Levin, Qijin Chen, Ioan Kosztin
On the basis of the observed short coherence lengths in the cuprates we argue that a BCS-Bose-Einstein condensation (BEC) crossover approach is an appropriate starting point for co…
Nodal Quasiparticles versus Phase Fluctuations in High Tc Superconductors: An Intermediate Scenario
Qijin Chen, Ioan Kosztin, K. Levin
We explore a BCS Bose Einstein crossover scenario for and its implications for the superfluid density and specific heat. The low lying excitations consist of no…
Unusual thermodynamical and transport signatures of short coherence length superconductors: A BCS Bose-Einstein crossover approach
Qijin Chen, Ioan Kosztin, K. Levin
In this paper we present predictions for thermodynamic and transport properties of a BCS Bose-Einstein crossover theory, below Tc, which theory satisfies the reasonable constraints…
