Enhance students learning outcomes by redesigning individual learning activities into group activities for introductory level Physics courses
Kalani Hettiarachchilage, Neel Haldolaarachchige
The evolution of science education is a dynamic process driven by advances in pedagogy, technology, and especially, our understanding of how students learn. Educators are exploring…
Signature of topological crystalline insulating behavior in new B2X2Zn (X=Ir, Rh, Co) compound from first-principles Computation
J. Howard, A. Rodriguez, N. Haldolaarachchige +1
Recent attempts at topological materials have revealed a large class of materials that show gapless surface states protected by time-reversal symmetry and crystal symmetries. Among…
The Bose-Hubbard model on a triangular lattice with diamond ring-exchange
V. G. Rousseau, K. Hettiarachchilage, K. -M. Tam +2
Ring-exchange interactions have been proposed as a possible mechanism for a Bose-liquid phase at zero temperature, a phase that is compressible with no superfluidity. Using the Sto…
Ferromagnetic phase in the polarized two-species bosonic Hubbard Model
Kalani Hettiarachchilage, Valéry G. Rousseau, Ka-Ming Tam +2
We recently studied a doped two-dimensional bosonic Hubbard model with two hard-core species, with different masses, using quantum Monte Carlo simulations [Phys. Rev. B 88, 161101(…
Using off-diagonal confinement as a cooling method
V. G. Rousseau, K. Hettiarachchilage, M. Jarrell +2
In a recent letter [Phys. Rev. Lett. 104, 167201 (2010)] we proposed a new confining method for ultracold atoms on optical lattices, based on off-diagonal confinement (ODC). This m…
