Understanding non-Fermi liquids in dimensions higher than one, has been a subject of great interest. Such phases may serve as parent states for other unconventional phases of quantum matter, in a similar manner that conventional broken symmetry states can be understood as instabilities of the Fermi liquid. In this work, we investigate the emergence of a novel non-Fermi liquid in two dimensions, where the fermions with quadratic band-touching dispersion interact with the Bose metal. The bosonic…

Recent Developments in Non-Fermi Liquid Theory

Non-Fermi liquids are unconventional metals whose physical properties deviate qualitatively from those of noninteracting fermions due to strong quantum fluctuations near Fermi surfaces. They arise

Luttinger liquid theory of one-dimensional quantum fluids. I. Properties of the Luttinger model and their extension to the general 1D interacting spinless Fermi gas

The explicitly soluble Luttinger model is used as a basis for the description of the general interacting Fermi gas in one dimension, which will be called 'Luttinger liquid theory', by analogy with

Fracton Critical Point in Higher-Order Topological Phase Transition

The theory of quantum phase transitions separating different phases with distinct symmetry patterns at zero temperature is one of the foundations of modern quantum many-body physics. In this paper we


Fracton phases constitute a new class of quantum state of matter. They are characterized by excitations that exhibit restricted mobility, being either immobile under local Hamiltonian dynamics or

Quantum criticality: competing ground states in low dimensions

Nonzero temperature dynamic properties near quantum critical points and possible quantum phases and transitions in the two-dimensional electron gas on a square lattice are discussed.

Condensed matter: Scratching the Bose surface

It seems bosons may assume similar characteristics to fermion systems in the low-temperature regime typical of Bose–Einstein condensation.

Four-body ring-exchange interactions and anyonic statistics within a minimal toric-code Hamiltonian

Ring-exchange interactions are basic elements needed for realizing topological quantum computation. These interactions and anyonic statistics have been engineered using ultracold atoms in an optical
