Influence of Charge Order on the Ground States of TMTTF Molecular Salts
, 2003 (TMTTF)2AsF6 and (TMTTF)2SbF6 are both known to undergo a charge ordering phase transition, though their ground states are different. The ground state of the first is Spin-Peierls, and the second is an antiferromagnet.

Ground subsidence due to the backfill pressure in tunnel boring machine [PDF]
Proceedings of the International Association of Hydrological Sciences, 2020 In shield tunnel boring machine constructions, backfill pressure affects surface settlement and the stability of other underground structures nearby. Therefore, it is essential to pre-calculate backfill pressure in the design stage.

Chromium at High Pressures: Weak Coupling and Strong Fluctuations in an Itinerant Antiferromagnet [PDF]
, 2008 The spin- and charge-density-wave order parameters of the itinerant antiferromagnet chromium are measured directly with non-resonant x-ray diffraction as the system is driven towards its quantum critical point with high pressure using a diamond anvil ...
