Vestigial Nematic Order at Zero Temperature in Two-Dimensional Frustrated Quantum Antiferromagnets
Matthew C. O'Brien, Eduardo Fradkin
The phase diagram of the two-dimensional quantum - Heisenberg antiferromagnet on a square lattice is a long-standing open problem. Despite recent advances in numerical te…
Charge order-driven nematicity in the nickel-pnictide superconductor BaSrNiAs
Thomas Johnson, Camille Bernal-Choban, Sangjun Lee +8
Nematic order refers to the spontaneous breaking of rotational symmetry while preserving translational symmetry. First identified in classical liquid crystals, nematic order arises…
Intertwined order of generalized global symmetries
Benjamin Moy, Eduardo Fradkin
We investigate the interplay of generalized global symmetries in 2+1 dimensions in a lattice model that couples a clock model to a gauge theory via a…
Measurement of the dynamic charge susceptibility near the charge density wave transition in ErTe
Dipanjan Chaudhuri, Qianni Jiang, Xuefei Guo +9
A charge density wave (CDW) is a phase of matter characterized by a periodic modulation of the valence electron density accompanied by a distortion of the lattice structure. The mi…
Interplay of Quantum and Thermal Fluctuations in Two-Dimensional Randomly Pinned Charge Density Waves
Matthew C. O'Brien, Eduardo Fradkin
The interplay between quantum and thermal fluctuations in the presence of quenched random disorder is a long-standing open theoretical problem which has been made more urgent by ad…
Absence of a bulk charge density wave signature in x-ray measurements of UTe
Caitlin S. Kengle, Dipanjan Chaudhuri, Xuefei Guo +12
The long-sought pair density wave (PDW) is an exotic phase of matter in which charge density wave (CDW) order is intertwined with the amplitude or phase of coexisting, superconduct…
Microscopic Model for Fractional Quantum Hall Nematics
Songyang Pu, Ajit C. Balram, Joseph Taylor +2
Geometric fluctuations of the density mode in a fractional quantum Hall (FQH) state can give rise to a nematic FQH phase, a topological state with a spontaneously broken rotational…
An Exactly Solvable Model of Randomly Pinned Charge Density Waves in Two Dimensions
Matthew C. O'Brien, Eduardo Fradkin
The nature of the interplay between fluctuations and quenched random disorder is a long-standing open problem, particularly in systems with a continuous order parameter. This lack…
Mapping the magneto-structural quantum phases of Mn3O4
M. Kim, X. M. Chen, E. Fradkin +2
We present temperature-dependent x-ray diffraction and temperature- and field-dependent Raman scattering studies of single crystal Mn3O4, which reveal the novel magnetostructural p…
Quantum dimer models and exotic orders
K. S. Raman, E. Fradkin, R. Moessner +2
We discuss how quantum dimer models may be used to provide "proofs of principle" for the existence of exotic magnetic phases in quantum spin systems.
Raman scattering studies of temperature- and field-induced melting of charge order in (La,Pr,Ca)MnO
M. Kim, H. Barath, S. L. Cooper +5
We present Raman scattering studies of the structural and magnetic phases that accompany temperature- and field-dependent melting of charge- and orbital-order (COO) in La0.5Ca0.5Mn…
