Comment on"Delayed luminescence of biological systems in terms of coherent states"[Phys. Lett. A 293 (2002) 93]

Popp and Yan [F. A. Popp, Y. Yan, Phys. Lett. A 293 (2002) 93] proposed a model for delayed luminescence based on a single time-dependent coherent state. We show that the general solution of their model corresponds to a luminescence that is a linear function of time. Therefore, their model is not compatible with any measured delayed luminescence. Moreover, the functions that they use to describ...

8 Comment on “ Exposed - Key Weakness of αη ” [ Phys . Lett . A 370

We show that the claim of insecurity of the Y-00 (or αη) cryptosystem made by C. Ahn and K. Birnbaum in Phys. Lett. A 370 (2007) 131-135 even under ciphertextonly heterodyne attack, as well as the unfavorable security comparison between αη and an additive stream cipher for all kinds of attacks, is based on invalid extrapolations of Shannon’s random cipher analysis to two concrete ciphers. We ge...

Reply to : “ Comment on : ‘ Chiral anomalies and rooted staggered fermions ’ [ Phys . Lett . B 649 ( 2007

I respond to the Bernard et al. comment on my Letter “Chiral anomalies and rooted staggered fermions”. © 2007 Published by Elsevier B.V. In their comment on my Letter “Chiral anomalies and rooted staggered fermions” [1], Bernard, Golterman, Shamir, and Sharpe [2] do not address the main point that the chiral symmetry group for the rooted theory has a higher rank than the target theory. This imm...
