Boson Hubbard model with weakly coupled Fermions (2008)

Lutchyn, R. M., Tewari, S., Sarma, S. Das

Using an imaginary-time path integral approach, we develop the perturbation theory suited to the boson Hubbard model, and apply it to calculate the effects of a dilute gas of spin-polarized fermions...

Blue Quantum Fog: Chiral Condensation in Quantum Helimagnets (2005)

Tewari, S., Belitz, D., Kirkpatrick, T. R.

It is shown that a condensation transition involving a chiral order parameter can occur in itinerant helimagnets, in analogy to the transition between the isotropic phase and the phase known as blue...

Infrared Hall angle in the d-density-wave state: A comparison of theory and experiment (2004)

Tewari, S., Chakravarty, S., Fjaerestad, J. O., Nayak, C., Thompson, R. S.

Infrared Hall measurements in the pseudogap phase of the high-T-c cuprates are addressed within the framework of the ordered d-density-wave state. The zero-temperature Hall frequency omega(H) is...

Plant defense multigene families: II Evolution of coding sequence and differential expression of PR10 genes in Pisum (2003)

Tewari, S., Brown, S. M., Kenyon, P., Balcerzak, M., Fristensky, B.

While it is not possible to directly the observe evolution of multigene families, the best alternative is to compare orthologous family members among several closely-related species with varying...
