Strong-coupling expansion for ultracold bosons in an optical lattice at finite temperatures in the presence of superfluidity

Manjari Gupta, H. R. Krishnamurthy, J. K. Freericks

We develop a strong-coupling () expansion technique for calculating the density profile for bosonic atoms trapped in an optical lattice with an overall harmonic trap at fi…
