Higgs Bosons in D-wave Superconductors
Yafis Barlas, C. M. Varma
The concept of "broken symmetry", that the symmetry of the vacuum may be lower than the Hamiltonian of a quantum theory, plays an important role in modern physics. A manifestation…
Violation of Onsager Reciprocity in Underdoped Cuprates ?
C. M. Varma, Victor M. Yakovenko, A. Kapitulnik
One of the canons of condensed matter physics is the Onsager Reciprocity principle in systems in which the Hamiltonian commutes with the time-reversal operator. Recent results of m…
Theory of the Quantum Critical Fluctuations in Cuprates
Vivek aji, C. M. Varma
The statistical mechanics of the time-reversal and inversion symmetry breaking order parameter, possibly observed in the pseudogap region of the phase diagram of the Cuprates, can…
Topological Transition in the Fermi Surface of Cuprate Superconductors in the Pseudogap Regime
C. M. Varma, Lijun Zhu
The angle-resolved photoemission spectroscopy studies on cuprates in the pseudogap region reveal an extraordinary topological transition in which the ground state changes from one…
Josephson effect for superconductors lacking center of inversion
Brigitte Leridon, Tai-Kai Ng, C. M. Varma
Due to the absence of a center of inversion in some superconducting compounds, a p-wave admixture to the dominant d-wave order parameter must exist. If time-reversal is also violat…
Tilting instability and other anomalies in the flux-lattice in some magnetic superconductors
T. K. Ng, C. M. Varma
The flux-line lattice in the compound , which has a tendency to ferromagnetic order in the a-b plane is studied with external magnetic field direction close to the c-ax…
