Amplitude spectroscopy of two coupled qubits
... quasienergies crossing, which depend on the system parameters. It is well known that when the amplitude of the driving field and the control parameter change, the quasienergies of different symmetry classes may cross, but if they are of the same symmetry class, they form an anticrossing. As a result ...

What is the Entropy in Entropic Gravity?
... The existence of a profound relationship between gravity and entropy has been recognized since the formulation of the laws of black hole mechanics [1] and the derivation of the BekensteinHawking entropy [2, 3]. More recently, ideas such as the holographic principle [4, 5], black hole complementarity ...

3rd Set of Note for Chem 655
... The first angular momentum is specified by reporting the quantum numbers j1 and mj1 and the j2 and mj2 specify the second angular momentum that is coupled to the 1st. The overall combined state is then |j1,mj1;j2,mj2> Do each of these operators commute? For independent sources of angular momentum, a ...
