Manipulable compact many-body localization and absence of superfluidity in geometrically frustrated systems
Xinyao Zhang, Matheus S. M. de Sousa, Xinyi Li +2
Geometric frustration is known to completely damage kinetic processes of some of the orbitals (and their associated quantum coherence) as to produce flat bands in the non-interacti…
A universal low-temperature fluctuation of unconventional superconductivity revealed: Smoking gun favors Galilean bosonic superfluidity
Anthony Hegg, Ruoshi Jiang, Jie Wang +4
Low-temperature thermal fluctuations offer an essential window in characterizing the true nature of a quantum state of matter, a quintessential example being Fermi liquid theory. I…
Showcasing the necessity of the principle of relative motion in physical statistics: Inconsistency of the `segmented Fermi surface'
Wei Ku, Anthony Hegg
The hunt for exotic properties in flowing systems is a popular and active field of study, and has recently gained renewed attention through claims such as a ``segmented Fermi surfa…
Transport in the emergent Bose liquid: Bad metal, strange metal, and weak insulator, all in one system
Tao Zeng, Anthony Hegg, Long Zou +2
Non-saturating high-temperature resistivity ("bad metal"), T-linear low-temperature resistivity ("strange metal"), and a crossover to activation-free growth of the resistivity in t…
Probing a Bose Metal via Electrons: Inescapable non-Fermi liquid scattering and pseudogap physics
Xinlei Yue, Anthony Hegg, Xiang Li +1
Non-Fermi liquid behavior and pseudogap formation are among the most well-known examples of exotic spectral features observed in several strongly correlated materials such as the h…
Geometric frustration produces long-sought Bose metal phase of quantum matter
Anthony Hegg, Jinning Hou, Wei Ku
Two of the most prominent phases of bosonic matter are the superfluid with perfect flow and the insulator with no flow. A now decades-old mystery unexpectedly arose when experiment…
Pressure-induced melting of magnetic order and emergence of new quantum state in alpha-RuCl3
Zhe Wang, Jing Guo, F. F. Tafti +19
Here we report the observation of pressure-induced melting of antiferromagnetic (AFM) order and emergence of a new quantum state in the honeycomb-lattice halide alpha-RuCl3, a cand…
Exact Strongly Coupled Fixed Point in Theory
Anthony Hegg, Philip W. Phillips
We show explicitly how a strongly coupled fixed point can be constructed in scalar theory from the solutions to a non-linear eigenvalue problem. The fixed point exists only…
Breakdown of self-averaging in the Bose glass
Anthony Hegg, Frank Krüger, Philip W. Phillips
We study the square-lattice Bose-Hubbard model with bounded random on-site energies at zero temperature. Starting from a dual representation obtained from a strong-coupling expansi…
