Large quantum field theory
JA Gracey - International Journal of Modern Physics A, 2018 - World Scientific
We review the development of the large N method, where N indicates the number of
flavours, used to study perturbative and nonperturbative properties of quantum field theories …

Non-hermitian strongly interacting Dirac fermions
Exotic quantum phases and phase transition in the strongly interacting Dirac systems have
attracted tremendous interests. On the other hand, non-Hermitian physics, usually …

Quantum phase transitions in Dirac fermion systems
A key problem in the field of quantum criticality is to understand the nature of quantum phase
transitions in systems of interacting itinerant fermions, motivated by experiments on a variety …

Emergent spacetime supersymmetry in 3D Weyl semimetals and 2D Dirac semimetals
Supersymmetry (SUSY) interchanges bosons and fermions but no direct evidence of it has
been revealed in nature yet. In this Letter, we observe that fluctuating pair density waves …

Yukawa conformal field theories and emergent supersymmetry
We study conformal field theories (CFTs) with Yukawa interactions in dimensions between 2
and 4; they provide UV completions of the Nambu–Jona-Lasinio and Gross–Neveu models …

Fermion-induced quantum critical points
A unified theory of quantum critical points beyond the conventional Landau–Ginzburg–
Wilson paradigm remains unknown. According to Landau cubic criterion, phase transitions …

Probing quantum criticality using nonlinear Hall effect in a metallic Dirac system
Interaction-driven symmetry breaking in a metallic (doped) Dirac system can manifest in the
spontaneous gap generation at the nodal point buried below the Fermi level. Across this …
