In the context of false vacuum decay at zero temperature, it is well known that bubbles expand with uniform proper acceleration. We show this uniformly accelerating expansion suffers from an instability related to bubble size. This can be observed in Minkowski spacetime as a tachyonic mode spectrum fluctuations for energy functional reference frame which wall appears static. such frame, arbitra...

The electrical and thermo-electrical transport properties of the semimetal TaAs2 have been measured in a magnetic field applied along [?2 0 1] direction. resulting dependences resistivity as well Hall, Seebeck, Nernst coefficients below T ? 100 K can be satisfactorily described within two-band model consisting electron hole pockets. At low temperature, all exhibit significant contributions from...
