Magnetic long-range order at finite temperature in two-dimensional hyperbolic lattices
Alexander Hickey, Joseph Maciejko
Infrared singularities of gapless Goldstone modes preclude magnetic long-range order at finite temperature in conventional two-dimensional systems. By studying the spin- Heisenb…
Lieb-Schultz-Mattis constraints for hyperbolic lattices
G. Shankar, Joseph Maciejko
The Lieb-Schultz-Mattis (LSM) theorem and its higher-dimensional extensions forbid the existence of a unique, symmetric, and gapped ground state at fractional fillings in quantum m…
Strain-induced Berry phase in chiral superconductors
Canon Sun, Marcel Franz, Joseph Maciejko
We study the topology of the order parameter in the intermediate phase between the superconducting and time-reversal symmetry breaking transitions of a superconductor un…
Hyperbolic Spin Liquids
Patrick M. Lenggenhager, Santanu Dey, Tomáš Bzdušek +1
Hyperbolic lattices present a unique opportunity to venture beyond the conventional paradigm of crystalline many-body physics and explore correlated phenomena in negatively curved…
Mixed-symmetry superconductivity and the energy gap
Pramodh Senarath Yapa, Xinyu Guo, Joseph Maciejko +1
The symmetry of the superconducting order parameter, or simply the ``gap'', provides certain constraints on the actual mechanism that gives rise to pairing and ultimately to superc…
Topological Landau Theory
Canon Sun, Joseph Maciejko
We present an extension of Landau's theory of phase transitions by incorporating the topology of the order parameter. When the order parameter comprises several components arising…
