Novel criticality of Dirac fermions from lattice symmetry breaking
Elliot Christou, Fernado de Juan, Frank Krüger
We consider the role of spontaneous lattice symmetry breaking in strongly interacting two dimensional Dirac systems. The fermion induced quantum (multi-)criticality is described by…
Quantum Order-by-Disorder in Strongly Correlated Metals
Andrew G. Green, Gareth Conduit, Frank Kruger
Entropic forces in classical many-body systems, e.g. colloidal suspensions, can lead to the formation of new phases. Quantum fluctuations can have similar effects: spin fluctuation…
Entanglement entropies and fermion signs of critical metals
N. Kaplis, F. Krüger, J. Zaanen
The fermion sign problem is often viewed as a sheer inconvenience that plagues numerical studies of strongly interacting electron systems. Only recently, it has been suggested that…
Electronic spin-triplet nematic with a twist
G. Hannappel, C. J. Pedder, F. Krüger +1
We analyze a model of itinerant electrons interacting through a quadrupole density-density repulsion in three dimensions. At the mean field level, the interaction drives a continuo…
Bose and Mott Glass Phases in Dimerized Quantum Antiferromagnets
S. J. Thomson, F. Krüger
We examine the effects of disorder on dimerized quantum antiferromagnets in a magnetic field, using the mapping to a lattice gas of hard-core bosons with finite-range interactions.…
Magnetic hard-axis ordering near ferromagnetic quantum criticality
F. Krüger, C. J. Pedder, A. G. Green
We investigate the interplay of quantum fluctuations and magnetic anisotropies in metallic ferromagnets. Our central result is that fluctuations close to a quantum critical point c…
