Phase diagram and Ashkin-Teller universality in the classical square-lattice Heisenberg-compass model
Yuchen Fan
We determine the finite-temperature phase diagram and critical behavior of the classical square-lattice Heisenberg-compass model using large-scale Monte Carlo simulations and finit…
Liquid-gas analog multicriticality in a frustrated Ising bilayer
Yuchen Fan
We report the discovery of a multicritical point that extends the liquid-gas paradigm to systems with competing symmetry-breaking orders. Using large-scale Monte Carlo simulations…
Emergent criticality in fully frustrated quantum magnets
Yuchen Fan, Ning Xi, Changle Liu +2
Phase transitions in condensed matter are often linked to exotic emergent properties. We study the fully frustrated bilayer Heisenberg antiferromagnet to demonstrate that an applie…
Fluctuation-induced first order phase transitions in Kitaev-like honeycomb magnet
Yuchen Fan, Yuan Wan
We study numerically a bosonic analog of the Kitaev honeycomb model, which is a minimal model for quantum magnets with honeycomb lattice geometry. We construct its phas…
Quantum-critical scaling at the Bose-glass transition of the 3d diluted Heisenberg antiferromagnet in a field
Yuchen Fan, Rong Yu, Tommaso Roscilde
The nature of the superfluid-to-Bose-glass (SF-BG) quantum phase transition, occurring in systems of interacting bosons immersed in a disordered environment, remains elusive. One f…
A Better Upper Bound of Hausdorff Measure of the Cartesian Product of the Middle Third Cantor Set with Itself Compare to Others'
Yuchen Fan
After the correction of an inaccurate result in the reference, the author uses five different methods, and gets five different inequalities on the Hausdorff measure of the Cartesia…
Phase diagram and quantum criticality of Heisenberg spin chains with Ising-like interchain couplings -- Implication to YbAlO
Yuchen Fan, Jiahao Yang, Weiqiang Yu +2
Motivated by recent progress on field-induced phase transitions in quasi-one-dimensional quantum antiferromagnets, we study the phase diagram of antiferromagnetic Heisenber…
