Jul 18 at 7:13 | comment | added | Sanjana | I am not sure about this but does string theory with $g_s=0$ count given that such systems have an upper limit of temperature called the Hagedorn temperature and $E_{\text{Hagedorn}}=k_B T_{\text{Hagedorn}}$? | |
Jun 13 at 14:47 | comment | added | Roman | The Sturm–Liouville theorem states quite generally that for this class of problems (Hamiltonians etc.) there is a minimum, but no maximum, eigenvalue. | |

Jun 13 at 8:02 | comment | added | Norbert Schuch | Regarding "phenomonological restrictions", in quantum information (or maybe better mathematical physics?) one has to limit the energy in the system, in order to get well-behaved quantities such as channel capacities. (One typically bounds sth. like the average energy, rather than the maximum energy, and the bound itself is arbitrary, and the e.g. capacities one obtains will depend on the bound on chooses. It is basically capturing the idea that you are willing to invest a certain amount of energy into your system; depending on that amount, there is a rate at which you can transmit ... | |
