  • A triangular-lattice organic conductor κ-(BEDT-TTF)4Hg2.89 Br8 is a promising doped spin liquid candidate which also exhibits superconductivity. Here the authors report thermoelectric measurements under pressure and find a quantum critical phase that could be correlated to BEC-like superconductivity.

  • The understanding of quantum effects in electronic crystallization is limited. Murase et al. report spatio-temporal dynamics in an organic material, with distinct nucleation and growth signatures, demonstrating larger growth rates than in the classical case due to quantum nature of electrons.

  • Geometrically frustrated spin-systems do not order magnetically even at absolute zero, forming instead a spin liquid or a glassy state. An organic conductor in which the charges, rather than spins, are frustrated now shows a similar absence of long-range order, resulting in a charge-cluster glass at low temperature.

  • Photoinduced phase transition is a central issue in the field of non-equilibrium quantum physics. Here, the authors demonstrate that a terahertz electric-field pulse changes a Mott insulator of an organic molecular compound to a macroscopically polarized charge-order state.

  • A quantum spin liquid is an intriguing exotic state of matter involving a magnetic system in which a magnetically ordered ground state at low temperatures is avoided despite strong interactions between magnetic units, due to quantum fluctuations. Experimental evidence for the existence of such a state has become available, but there are many fundamental questions about this novel state. This study uses an advanced magnetic probing technique, called muon spin rotation, to study a molecular layered system that is widely regarded as a prime candidate for quantum spin liquid. A complex magnetic phase diagram for this system is determined and characteristic critical properties of the spin liquid are measured, thereby providing important new insights into this exotic state of matter.

  • Irradiation with a strong terahertz electric-field pulse is found to induce a Mott transition in an organic molecular compound. The metallization is attributed to an impulsive dielectric breakdown.
