Parent Hamiltonians for lattice Halperin states from free-boson conformal field theories
Nuclear Physics B, 2017 We introduce a family of many-body quantum states that describe interacting spin one-half hard-core particles with bosonic or fermionic statistics on arbitrary one- and two-dimensional lattices.

Massive skyrmions in quantum Hall ferromagnets
, 2000 We apply the theory of elasticity to study the effects of skyrmion mass on lattice dynamics in quantum Hall systems. We find that massive Skyrme lattices behave like a Wigner crystal in the presence of a uniform perpendicular magnetic field.

Translationally Invariant Non-Fermi-Liquid Metals with Critical Fermi Surfaces: Solvable Models
Physical Review X, 2018 We construct examples of translationally invariant solvable models of strongly correlated metals, composed of lattices of Sachdev-Ye-Kitaev dots with identical local interactions.

Floquet engineering the band structure of materials with optimal control theory
Physical Review Research, 2022 We demonstrate that the electronic structure of a material can be deformed into Floquet pseudobands with arbitrarily tailored shapes. We achieve this goal with a combination of quantum optimal control theory and Floquet engineering.

Majorana diagrammatics for quantum spin-1/2 models
SciPost Physics CoreA diagrammatic formalism for lattices of 1/2 is developed. It is based on an unconstrained mapping between spin and Majorana operators. This allows the use of standard tools of diagrammatic quantum many-body theory without requiring projections.

Low-energy structure of spiral spin liquids
Physical Review Research, 2022 In this paper we identify a previously unexplored type of topological defect in spiral spin liquids—the momentum vortex—and reveal its dominant role in shaping the low-energy physics of such systems.

Analysis of quantum spin models on hyperbolic lattices and Bethe lattice
, 2016 The quantum XY, Heisenberg, and transverse field Ising models on hyperbolic lattices are studied by means of the Tensor Product Variational Formulation algorithm. The lattices are constructed by tessellation of congruent polygons with coordination number

Phase Transitions in Three-Dimensional Bosonic Systems in Optical Lattices
, 2014 We formulate the Collective Quantum Field Theory for three-dimensional bosonic optical lattices and evaluate its consequences in a mean-field approximation to two collective fields, proposed by Fred Cooper et al.
