  • Spectroscopic signatures of the Mott transition on the anisotropic triangular lattice 

    Tiwari, Rajarshi (2014)
    We use a new Monte Carlo method to study the Mott transition on the anisotropic-triangular-lattice Hubbard model. Our real space approach accurately treats the emergence of non-trivial magnetic correlation in this frustrated ...
  • NONCOLLINEAR MAGNETIC ORDER IN THE DOUBLE PEROVSKITES: DOUBLE EXCHANGE ON A GEOMETRICALLY FRUSTRATED LATTICE 

    Tiwari, Rajarshi (2013)
    Double perovskites (DPs) of the form A2BB′ O6 usually involve a transition metal ion, B, with a large magnetic moment, and a nonmagnetic ion B′. While many DPs are ferromagnetic, studies on the underlying model reveal the ...
  • Microstructures 

    Cross, Graham (World Intellectual Property Organization, World Intellectual Property Organization, 2003)
    A method for forming a microstructures is described. The method comprises: depositing a seed material on a substrate; growing a nanotube from the seed material; depositing microstructure material on the substrate to embed ...
  • Visualizing the Mott transition 

    Tiwari, Rajarshi (2012)
    Correlated electronic systems involve strong short-range repulsion. At integer filling, the primary effect of correlation is the emergence of an insulating state where band theory predicts a metal. Understanding the ...
  • Angle of Arrival Estimation Via Small IoT Devices: Miniaturized Arrays vs MIMO Antennas 

    Zandamela, Abel; Chiumento, Alessandro; Marchetti, Nicola; Narbudowicz, Adam (2022)
    This tutorial discusses the problem of Angle-of-Arrival (AoA) estimation from small Internet of Things (IoT) devices. It reviews the limitations and challenges of existing miniaturization strategies, which involve classical ...
