Correlation between battery material performance and cooperative electron-phonon interaction in LiCoMnO
Krishna Rao Ragavendran, Prabhat Mandal, Sudhakar Yarlagadda
Understanding the basic physics related to archetypal lithium battery material (such as LiCoMnO) is of considerable interest and is expected to aid designing of c…
Temperature dependence of long coherence times of oxide charge qubits
A. Dey, S. Yarlagadda
The ability to maintain coherence and control in a qubit is a major requirement for quantum computation. We show theoretically that long coherence times can be achieved above boili…
Study of long-range orders of hard-core bosons coupled to cooperative normal modes in two-dimensional lattices
Amrita Ghosh, Sudhakar Yarlagadda
Understanding the microscopic mechanism of coexisting long-range orders (such as lattice supersolidity) in strongly correlated systems is a subject of immense interest. We study th…
Charge and orbital order due to cooperative Jahn-Teller effect in manganite chains
Ravindra Pankaj, Sudhakar Yarlagadda
We derive an effective Hamiltonian that takes into account the quantum nature of phonons and models cooperative Jahn-Teller effect in the adiabatic regime and at strong electron-ph…
