Spin-density-wave order in cuprates
We study the nature of the two-dimensional quantum critical point separating two phases with and without long-range spin-density-wave order, which has been recently observed in cuprate
Phase diagram and multicritical behaviors of mixtures of three-dimensional bosonic gases
We investigate the Bose-Einstein condensation (BEC) patterns, the critical and multicritical behaviors of three-dimensional mixtures of bosonic gases with density-density interactions, characterized
Interacting N-vector order parameters with O(N) symmetry
We consider the critical behavior of the most general system of two N-vector order parameters that is O(N) invariant. We show that it may a have a multicritical transition with enlarged symmetry
First order phase transition in the frustrated triangular antiferromagnet CsNiCl3.
These results represent the first experimental evidence that the 120 degrees phase transition is weakly first order and contradict the popular notion of new universality classes for chiral systems.
The finite-temperature chiral transition in QCD with adjoint fermions
We study the nature of the finite-temperature chiral transition in QCD with Nf light quarks in the adjoint representation (aQCD). Renormalization-group arguments show that the transition can be
Topological phase transitions in frustrated magnets
The role of topological excitations in frustrated Heisenberg antiferromagnets between two and three spatial dimensions is considered. In particular, the antiferromagnetic Heisenberg model on a
Analytic and numerical bootstrap of CFTs with $O(m)\times O(n)$ global symmetry in 3D
Motivated by applications to critical phenomena and open theoretical questions, we study conformal field theories with $O(m)\times O(n)$ global symmetry in $d=3$ spacetime dimensions. We use both
Determining the order of chiral phase transition in QCD from conformal bootstrap
There has been a long-standing debate if the chiral phase transition in two-flavor massless QCD is first order or second order. The previous arguments based on epsilon expansions, large N expansions,
Spin dynamics across the superfluid-insulator transition of spinful bosons
Bosons with nonzero spin exhibit a rich variety of superfluid and insulating phases. Most phases support coherent spin oscillations, which have been the focus of numerous recent experiments. These
High-order perturbative expansions of multi-parameter Phi^4 quantum field theories
We present high-order pertubative expansions of multi-parameter Phi^4 quantum field theories with an N-component fundamental field, containing up to 4th-order polynomials of the field.


Critical behavior of O(2)⊗O(N) symmetric models
We investigate the controversial issue of the existence of universality classes describing critical phenomena in three-dimensional statistical systems characterized by a matrix order parameter with
Multicritical phenomena in O(n_1)+O(n_2)-symmetric theories
We study the multicritical behavior arising from the competition of two distinct types of ordering characterized by O(n) symmetries. For this purpose, we consider the renormalization-group flow for
Nonperturbative renormalization-group approach to frustrated magnets
This article is devoted to the study of the critical properties of classical XY and Heisenberg frustrated magnets in three dimensions. We first analyze the experimental and numerical situations. We
Critical behavior of frustrated spin models with noncollinear order
We study the critical behavior of frustrated spin models with noncollinear order, including stacked triangular antiferromagnets and helimagnets. For this purpose we compute the field-theoretic
The N-component Ginzburg-Landau Hamiltonian with cubic anisotropy: a six-loop study
We consider the Ginzburg-Landau Hamiltonian with a cubic-symmetric quartic interaction and compute the renormalization-group functions to six-loop order in d=3. We analyze the stability of the
Chiral exponents in frustrated spin models with noncollinear order
We compute the chiral critical exponents for the chiral transition in frustrated two- and three-component spin systems with noncollinear order, such as stacked triangular antiferromagnets (STA).
Old and New Results on Multicritical Points
Thirty years after the Liu–Fisher paper on the bicritical and tetracritical points in quantum lattice gases, these multicritical points continue to appear in a variety of new physical contexts. This
