in Sinai oscillator trap
by L.Ermann, E.Vergini and D.L.Shepelyansky
arXiv:1605.02831[cond-mat.quant-gas]

















Quantum probability in (x,y) plane: 
a) ground state of Sinai oscillator, 
b) initial exited state m=24, 
e)steady state at time t=2000, 
f)theoretical Bose-Einstein distribution; 
here nonlinearity beta=4
