Ground state instability in nonrelativistic QFT and Euler–Heisenberg Lagrangian via holography
Abstract We study the ground state instability of a strongly coupled QFT with the $$z=2$$ z=2 Schrödinger symmetry in a constant electric field using probe branes holography. The system is $$N_f$$ Nf $${\mathcal {N}}=2$$ N=2 hypermultiplet fermions at zero charge density in the supergravity Schrödin...
