A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Decoupling of static and dynamic criticality in a driven Mott insulator
A. de la Torre, K. L. Seyler, M. Buchhold +12
Dynamically driven interacting quantum many-body systems have the potential to exhibit properties that defy the laws of equilibrium statistical mechanics. A widely studied model is…
Evidence for an extended critical fluctuation region above the polar ordering transition in LiOsO
Jun-Yi Shan, A. de la Torre, N. J. Laurita +8
Metallic LiOsO undergoes a continuous ferroelectric-like structural phase transition below = 140 K to realize a polar metal. To understand the microscopic interactions th…
Evidence for a Parity Broken Monoclinic Ground State in the S = 1/2 Kagomé Antiferromagnet Herbertsmithite
N. J. Laurita, A. Ron, J. W. Han +9
Nearest-neighbor interacting S = 1/2 spins on the ideal Kagomé lattice are predicted to form a variety of novel quantum entangled states, including quantum spin-liquid (SL) and val…
Valence bond phases of herbertsmithite and related copper kagome materials
M. R. Norman, N. J. Laurita, D. Hsieh
Recent evidence from magnetic torque, electron spin resonance, and second harmonic generation indicate that the prototypical quantum spin liquid candidate, herbertsmithite, has a s…
Evidence for the weakly coupled electron mechanism in an Anderson-Blount polar metal
N. J. Laurita, A. Ron, J. Shan +6
Over 50 years ago, Anderson and Blount proposed that ferroelectric-like structural phase transitions may occur in metals, despite the expected screening of the Coulomb interactions…
Electric field modulated topological magnetoelectric effect in BiSe
Mintu Mondal, Dipanjan Chaudhuri, Maryam Salehi +11
Topological insulators have been predicted to exhibit a variety of interesting phenomena including a quantized magnetoelectric response and novel spintronics effects due to spin te…
A compact broadband terahertz range quarter-wave plate
Liang Wu, A. Farid, N. J. Laurita +2
We detail the design and characterization of a terahertz range achromatic quarter-wave plate based on a stack of aligned variable thickness birefringent sapphire discs. The disc th…
Impurities or a neutral Fermi surface? A further examination of the low-energy ac optical conductivity of SmB
N. J. Laurita, C. M. Morris, S. M. Koohpayeh +3
Recent experiments have uncovered evidence of low energy excitations in the bulk of SmB that are perhaps associated with unconventional quasiparticles, bringing into question w…
Hierarchy of exchange interactions in the triangular-lattice spin-liquid YbMgGaO
Xinshu Zhang, Fahad Mahmood, Marcus Daum +7
The spin-1/2 triangular lattice antiferromagnet YbMgGaO has attracted recent attention as a quantum spin-liquid candidate with the possible presence of off-diagonal anisotrop…
Asymmetric splitting of an antiferromagnetic resonance via quartic exchange interactions in multiferroic hexagonal HoMnO
N. J. Laurita, Yi Luo, Rongwei Hu +4
The symmetric splitting of two spin-wave branches in an antiferromagnetic resonance (AFR) experiment has been an essential measurement of antiferromagnets for over half a century.…
