Cooperative Ring Exchange and Quantum Melting of Vortex Lattices in Atomic Bose-Einstein Condensates
Tarun Kanti Ghosh, G. Baskaran
Cooperative ring-exchange is suggested as a mechanism of quantum melting of vortex lattices in a rapidly-rotating quasi two dimensional atomic Bose-Einstein condensate (BEC). Using…
Condensed Matter Physics - Biology Resonance
G. Baskaran
The field of condensed matter physics had its genesis this century and it has had a remarkable evolution. A closer look at its growth reveals a hidden aim in the collective conscio…
K S Krishnan and the early experimental evidences for the Jahn-Teller Theorem
G. Baskaran
Jahn-Teller theorem, proposed in 1937, predicts a distortional instability for a molecule that has symmetry based degenerate electronic states. In 1939 Krishnan emphasized the impo…
Where are we in the theory of High Temperature Superconductors ?
G. Baskaran
In this talk I will briefly review our present theoretical understanding of some of the important issues in the high Tc cuprates. In view of its success, at a qualitative level and…
A Critique of ``A Critique of Two Metals''
P. W. Anderson, G. Baskaran
This is a critique of cond-mat/9709195 . This paper is being submitted at this time for archiving purposes.
g-on Mean Field Theory of the t-J Model
Flordivino Basco, Hiroshi Kohno, Hidetoshi Fukuyama +1
Implication of our recent proposal [J. Phys. Soc. Jpn. 65 (1996) 687] to treat large-amplitude gauge-field fluctuations around the slave-boson mean-field theory for the t-J model h…
Resonant Pair Tunneling and Singular effects of c-axis disorder in cuprates and organic superconductors
G. Baskaran
In the interlayer pair tunneling (ILPT) theory of superconductivity the large scale has its origin in the k-space locality of the inter layer pair tunneling matrix elements.…
Symmetry of the Gap Function in High- Superconductors
Mihir Arjunwadkar, D. G. Kanhere, G. Baskaran +1
One of the most debated issues related to high- superconductivity is the symmetry of the Cooper pair or the gap function. In this report, we present numerical results regardin…
Superconducting Gap Nodal Surface and Fermi Surface: their partial overlap in cuprates
G. Baskaran, D. G. Kanhere, Mihir Arjunwadkar +1
Electron correlation in cuprates leads to a global constraint on the gap function resulting in a gap nodal surface. We give physical argume…
Failure of Fermi Liquid Theory in 2-D: A Signal from Perturbation Theory
G. Baskaran
We study the perturbative correction to the ground state energy eigenvalue of a 2-dimensional dilute fermi gas with weak short-range two body repulsion. From the structure of the e…
A Toy Model of Interlayer Pair Hopping
V. N. Muthukumar, G. Baskaran
We extend the correlated electron model of Baskaran [Mod. Phys. Lett. {\bf B5}, 643(1991)] to the case of coupled layers. We show that the nature of the non-Fermi liquid ground sta…
Correlation Induced Vanishing of the Gap Function on the Fermi Surface in High Superconductors
G. Baskaran, D. G. Kanhere, Mihir Arjunwadkar +1
We present physical arguments as well as numerical evidence to show that the Cooper pair (gap) function vanishes on the Fermi surface in strongly correlated electron systems such a…
