How a Potentially Novel Effect Converts AC Current into DC Heat Flow
2021524
A novel currentinduced thermoelectric phenomenon, the nonlinear anomalous Ettingshausen effect, was discussed. As an example, the weak charge ordering state in an organic conductor α(BEDTTTF)_{2}I_{3} was focused on. This effect generates a transverse heat current with rectifying characteristics, namely unidirectionality even under AC fields.

No Mass Gap Phase Transition in Novel Massless Dirac Fermion Material
2021322
Using an organic massless Dirac fermion system, we found that massless Dirac fermions undergo a quantum phase transition without creating any mass gap even in the strong coupling regime.

What Dictates Nonlinear Behavior in Strongly Correlated Insulators?
202133
The nonlinear conduction (the deviation from Ohm's law) has been discovered universally in various correlated materials. This may be explained by the percolation conduction in disordered materials.
