Primary and secondary order parameters in the fully frustrated transverse-field Ising model on the square lattice
Using quantum Monte Carlo simulations and field-theory arguments, we study the fully frustrated transversefield Ising model on the square lattice for the purpose of quantitatively relating two different order parameters to each other. We consider a "primar ...
Amer Physical Soc2024Eight-vertex criticality in the interacting Kitaev chain
Frédéric Mila, Natalia Chepiga
We show that including pairing and repulsion into the description of one-dimensional spinless fermions, as in the domain wall theory of commensurate melting or the interacting Kitaev chain, leads, for strong enough repulsion, to a line of critical points i ...
AMER PHYSICAL SOC2023Thermal Ising Transition in the Spin-1/2 J(1)-J(2) Heisenberg Model
Frédéric Mila, Olivier Clément Romain Gauthé
Using an SU(2) invariant finite-temperature tensor network algorithm, we provide strong numerical evidence in favor of an Ising transition in the collinear phase of the spin-1/2 J(1)-J(2) Heisenberg model on the square lattice. In units of J(2), the critic ...
AMER PHYSICAL SOC2022Fabrication of glass suspended microchannel resonators
The goal of this project was to study if the fabrication of glass suspended microchannel resonators was possible. Through trial and error, the process parameters were determined, starting from the ideal dose in the dry etching process. The ideal size was d ...
2021Gaussian Multiplicative Chaos Through the Lens of the 2D Gaussian Free Field
The aim of this review-style paper is to provide a concise, self-contained and unified presentation of the construction and main properties of Gaussian multiplicative chaos (GMC) measures for log-correlated fields in 2D in the subcritical regime. By consid ...
POLYMAT2020Carving out OPE space and precise O(2) model critical exponents
We develop new tools for isolating CFTs using the numerical bootstrap. A "cutting surface" algorithm for scanning OPE coefficients makes it possible to find islands in high-dimensional spaces. Together with recent progress in large-scale semidefinite progr ...
