Platforms for the realization and characterization of Tomonaga-Luttinger liquids

Isabelle Bouchoule, Roberta Citro, Tim Duty +5

The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…

Longitudinal DC Conductivity in Dirac Nodal Line Semimetals: Intrinsic and Extrinsic Contributions

Vivek Pandey, Dayana Joy, Dimitrie Culcer +1

Nodal line semimetals, a class of topological quantum materials, exhibit a variety of novel phenomena due to their properties, such as bands touching on a one-dimensional line or a…

Conservation, crossing symmetry, and completeness in diagrammatic theories

Frederick Green

The diagrammatic analysis of interacting particle assemblies harbors a fundamental mismatch between two of its main implementations: Phi-derivable (conserving) approximations and p…

Competing Gauge Fields and Entropically-Driven Spin Liquid to Spin Liquid Transition in non-Kramers Pyrochlores

Daniel Lozano-Gómez, Vincent Noculak, Jaan Oitmaa +4

Gauge theories are powerful tools in theoretical physics, allowing complex phenomena to be reduced to simple principles, and are used in both high-energy and condensed matter physi…

Classical and quantum phases of the pyrochlore magnet with Heisenberg and Dzyaloshinskii-Moriya interactions

Vincent Noculak, Daniel Lozano-Gómez, Jaan Oitmaa +4

We investigate the ground state and critical temperature phase diagrams of the classical and quantum pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-…

Patterned bilayer graphene as a tunable, strongly correlated system

Z. E. Krix, O. P. Sushkov

Recent observations of superconductivity in Moire graphene have lead to an intense interest in that system, with subsequent studies revealing a more complex phase diagram including…
