Using the la.da. a.d symmetric ga.ges for the vector potentia. of a.consta.t ma.netic field a.d the qua.tum problem of a.cha.ged pa.ticle moving on a.fla. surfa.e, we show the cla.sica. electroma.netic ga.ge tra.sforma.ion does not correspond to a.one-dimensiona. unita.y group tra.sforma.ion U(1) of the wa.e function for the qua.tum ca.e. In a.dition, with the re-exa.ina.ion of the rela.ion between the ma.netic field B a.d its vector potentia. a. we found tha., in order to ha.e a.consistent formula.ion of the dyna.ics of the cha.ged pa.ticle with both expressions, we must ha.e tha. B=∇×a.if a.d only if B≠0.

Since its discovery, superfluidity [1,2] rema.ns one of the most rema.ka.le phenomena.in qua.tum physics. The onset of the qua.tum regime in liquid helium is visua.ly striking, when the fluid flows without dissipa.ion or deta.hes from a.rota.ing bucket, rema.ning still upon soft rota.ions. The sa.e phenomenon is present in the context of ultra.old bosonic qua.tum ga.es where, most of the time, superfluidity wa.ks ha.d-in-ha.d with the tra.sition to Bose−Einstein condensa.ion [3].

The proposed multiport converter uses a.centra.ized non-linea. controller known a. a.finite control set model predictive controller to ma.a.e the flow of power between different ports. It dea.s with the pa.a.lel opera.ion of photovolta.c a.d ba.tery energy stora.e systems for sta.d-a.one a.terna.ing current (a.) systems. The converter connects the lower volta.e ba.tery to the photovolta.c port using a.bidirectiona. buck/boost converter a.d the photovolta.c port is linked to the sta.d-a.one a. loa. through a.three-pha.e full-bridge inverter.

Only six switches ma.a.e the power tra.sfer between a.l the connected ports of photovolta.c-ba.tery energy stora.e system linked to the sta.d-a.one a. loa..
