Bootstrapping deconfined quantum tricriticality

SM Chester, N Su - Physical Review Letters, 2024 - APS
The paradigmatic example of deconfined quantum criticality is the Neel to valence bond
solid phase transition. The continuum description of this transition is the N= 2 case of the …

Spin-Peierls instability of the U (1) Dirac spin liquid

UFP Seifert, J Willsher, M Drescher, F Pollmann… - Nature …, 2024 - nature.com
Quantum fluctuations can inhibit long-range ordering in frustrated magnets and potentially
lead to quantum spin liquid (QSL) phases. A prime example are gapless QSLs with …

[PDF][PDF] Snowmass White Paper: The Numerical Conformal Bootstrap

D Poland, D Simmons-Duffin - arXiv preprint arXiv:2203.08117, 2022 - arxiv.org
The idea of the conformal bootstrap is to constrain and solve CFTs using physical
consistency conditions like symmetry, unitarity, and causality. By relying on nonperturbative …

Quantum Electrodynamics in Dimensions as the Organizing Principle of a Triangular Lattice Antiferromagnet

A Wietek, S Capponi, AM Läuchli - Physical Review X, 2024 - APS
Quantum electrodynamics in 2+ 1 dimensions (QED 3) has been proposed as a critical field
theory describing the low-energy effective theory of a putative algebraic Dirac spin liquid or …

At sufficiently low temperatures, interacting electron systems tend to develop orders.
Exceptions are quantum critical point (QCP) and quantum spin liquid (QSL), where …

Spin-Peierls instability of deconfined quantum critical points

D Hofmeier, J Willsher, UFP Seifert, J Knolle - Physical Review B, 2024 - APS
Deconfined quantum critical points (DQCPs) are putative phase transitions beyond the
Landau paradigm with emergent fractionalized degrees of freedom. The original example of …
