Click For Summary
V-Gauge and L-Gauge appear to be terms that are not widely recognized, leading to confusion in the discussion. Participants are seeking clarification and specific references to understand these concepts better. Some mention that Google searches yield unrelated results, such as wine bottle stoppers and Lego train sets. There is a suggestion that the terms might relate to ##R_\xi## gauges or quantum field theory (QFT). Overall, the conversation emphasizes the need for more context and accurate information regarding V-Gauge and L-Gauge.

Can you be more specific or at least provide a reference on where you found those terms? Google searches turn up a wine bottle stopper and Lego train sets. Are you instead referring to some ##R_\xi## gauges ? Do you have an understanding of QFT?
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
