We study quantum many-body systems in the presence of an exotic antiunitary translation or inversion symmetry involving time reversal. Based on a symmetry-twisting method and spectrum robustness, we propose that a half-integer spin chain that respects any of these two antiunitary crystalline symmetries in addition to the discrete Z2×Z2 global spin-rotation symmetry must either be gapless or possess degenerate ground states.

We study a relationship between conformally invariant boundary conditions and anomalies of conformal field theories (CFTs) in 1+1 dimensions. For a given CFT with a global symmetry, we consider symmetric “gapping potentials”, which are relevant perturbations to the CFT. If a gapping potential is introduced only in a subregion of the system, it provides a certain boundary condition to the CFT.

The ordinary Nernst effect (ONE) is a transverse thermoelectric conversion phenomenon in a conductor in which an electric field EONE is generated in the direction perpendicular to an applied temperature gradient ∇T and magnetic field H, where EONE ∝ H × ∇T.
