VO2 nanosheets: controlling the THz properties through strain engineering
Elsa Abreu, Mengkun Liu, Jiwei Lu +5
We investigate far-infrared properties of strain engineered vanadium dioxide nanosheets through epitaxial growth on a (100)R TiO2 substrate. The nanosheets exhibit large uniaxial s…
A lattice model for the SU(N) Neel-VBS quantum phase transition at large N
Ribhu K. Kaul, Anders W. Sandvik
We generalize the SU(N=2) square-lattice quantum magnet with nearest-neighbor antiferromagnetic coupling () and next-nearest-neighbor ferromagnetic coupling () to…
Universal Neel Temperature in Three-Dimensional Quantum Antiferromagnets
Songbo Jin, Anders W. Sandvik
We study three-dimensional dimerized S=1/2 Heisenberg antiferromagnets, using quantum Monte Carlo simulations of systems with three different dimerization patterns. We propose a wa…
Topological Hubbard model and its high-temperature quantum Hall effect
Titus Neupert, Luiz Santos, Shinsei Ryu +2
The quintessential two-dimensional lattice model that describes the competition between the kinetic energy of electrons and their short-range repulsive interactions is the repulsiv…
Two-orbital quantum spin model of magnetism in the iron pnictides
C. Liu, D. -X. Yao, A. W. Sandvik
We study a two-orbital spin model to describe (pi,0) stripe antiferromagnetism in the iron pnictides. The "double-spin" model has an on-site Hunds's coupling and inter-site interac…
State Space for Planar Majorana Zero Modes
R. Jackiw, S. -Y. Pi
Zero modes arising from a planar Majorana equation in the presence of vortices require an -dimensional state-space, where for even and…
General method for calculating the universal conductance of strongly correlated junctions of multiple quantum wires
Armin Rahmani, Chang-Yu Hou, Adrian Feiguin +3
We develop a method to extract the universal conductance of junctions of multiple quantum wires, a property of systems connected to reservoirs, from static ground-state computation…
Time-reversal symmetric hierarchy of fractional incompressible liquids
Luiz Santos, Titus Neupert, Shinsei Ryu +2
We provide an effective description of fractional topological insulators that include the fractional quantum spin Hall effect by considering the time-reversal symmetric pendant to…
Topological Quantum Glassiness
Claudio Castelnovo, Claudio Chamon
Quantum tunneling often allows pathways to relaxation past energy barriers which are otherwise hard to overcome classically at low temperatures. However, this is not always the cas…
Maximum entropy deconvolution of resonant inelastic x-ray scattering spectra
J. Laverock, A. R. H. Preston, D. Newby +2
Resonant inelastic x-ray scattering (RIXS) has become a powerful tool in the study of the electronic structure of condensed matter. Although the linewidths of many RIXS features ar…
Method to characterize spinons as emergent elementary particles
Ying Tang, Anders W. Sandvik
We develop a technique to directly study spinons (emergent spin S = 1/2 particles) in quantum spin models in any number of dimensions. The size of a spinon wave packet and of a bou…
Electrodynamics of Correlated Electron Materials
Dimitri N. Basov, Richard D. Averitt, Dirk van der Marel +2
We review studies of the electromagnetic response of various classes of correlated electron materials including transition metal oxides, organic and molecular conductors, intermeta…
On the Validity of the Tomonaga Luttinger Liquid Relations for the One-dimensional Holstein Model
Ka-Ming Tam, S. -W. Tsai, D. K. Campbell
For the one-dimensional Holstein model, we show that the relations among the scaling exponents of various correlation functions of the Tomonaga Luttinger liquid (LL), while valid i…
Fractional topological liquids with time-reversal symmetry and their lattice realization
Titus Neupert, Luiz Santos, Shinsei Ryu +2
We present a class of time-reversal-symmetric fractional topological liquid states in two dimensions that support fractionalized excitations. These are incompressible liquids made…
Electronic doping of graphene by deposited transition metal atoms
Jaime E. Santos, Nuno M. R. Peres, Joao M. B. Lopes dos Santos +1
We perform a phenomenological analysis of the problem of the electronic doping of a graphene sheet by deposited transition metal atoms, which aggregate in clusters. The sample is p…
Computational Studies of Quantum Spin Systems
Anders W. Sandvik
These lecture notes introduce quantum spin systems and several computational methods for studying their ground-state and finite-temperature properties. Symmetry-breaking and critic…
