Response to D.T. Son's comment on ``Is there a `most perfect fluid' consistent with quantum field theory?''
Thomas D. Cohen
This is a response to the comment, arXiv:0709.4651. It is noted that while the comment raises an extremely interesting and subtle point, the original conclusion that theoretically…
The chiral condensate in a constant electromagnetic field
Thomas D. Cohen, David A. McGady, Elizabeth S. Werbos
We study the shift of the chiral condensate in a constant electromagnetic field in the context of chiral perturbation theory. Using the Schwinger proper-time formalism, we derive a…
Is there a "most perfect fluid" consistent with quantum field theory?
Thomas D. Cohen
It was recently conjectured that the ratio of the shear viscosity to entropy density, , for any fluid always exceeds . This conjecture was motivated by quant…
Heavy baryons in the Skyrme model: the role of highly anharmonic collective motion
Thomas D. Cohen, Paul M. Hohler
In the heavy quark and large Nc limits, ordinary (exotic) heavy baryons can be considered as bound states of heavy mesons (anti-mesons)and chiral solitons. In these limits, the hea…
Strange results from chiral soliton models
Aleksey Cherman, Thomas D. Cohen
The standard collective quantization treatment of the strangeness content of the nucleon in chiral soliton models such as the Skyrmion is shown to be inconsistent with the semi-cla…
