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

Bootstrapping phase transitions in QCD and frustrated spin systems

In view of its physical importance in predicting the order of chiral phase transitions in QCD and frustrated spin systems, we perform the conformal bootstrap program of

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.

TLDR
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

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

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

Crossover to chirality in the critical behavior of the easy-axis antiferromagnet CsNiCl3.

We have measured the specific heat, C, of the easy-axis triangular lattice antiferromagnet CsNiCl 3 in order to investigate the critical behavior associated with a multicritical point when the chiral

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

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
