Quantum Criticality of Type-I and Critically Tilted Dirac Semimetals
Huanzhi Hu, Frank Krüger
We investigate the universality of an Ising symmetry breaking phase transition of tilted two-dimensional Dirac fermions, in the type-I phase as well as at the Lifshitz transition b…
Fermionic criticality of anisotropic nodal point semimetals away from the upper critical dimension: exact exponents
Mikolaj D. Uryszek, Frank Krüger, Elliot Christou
We consider the fermionic quantum criticality of anisotropic nodal point semimetals in spatial dimensions that disperse linearly in dimensions, and quadratica…
Non-linear soliton confinement in weakly coupled antiferromagnetic spin chains
H. Lane, C. Stock, S. -W. Cheong +3
We analyze the low-energy dynamics of quasi one dimensional, large- quantum antiferromagnets with easy-axis anisotropy, using a semi-classical non-linear sigma model. The saddle…
Novel criticality of Dirac fermions in the presence of emergent gauge fields
Elliot Christou, Fernado de Juan, Frank Krüger
We consider spontaneous symmetry breaking transitions of strongly interacting two-dimensional Dirac fermions minimally coupled to mass and emergent gauge field order parameters. Us…
