Superfluidity of "dirty" indirect excitons and magnetoexcitons in two-dimensional trap
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
The superfluid phase transition of bosons in a two-dimensional (2D) system with disorder and an external parabolic potential is studied. The theory is applied to experiments on ind…
Superfluidity of "dirty" indirect magnetoexcitons in coupled quantum wells in high magnetic field
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
Superfluidity in the quasi-two-dimensional (2D) system of spatially indirect magnetoexcitons in coupled quantum wells (CQW) and unbalanced two-layer electron system in high magneti…
Phase transitions in a system of indirect magnetoexcitons in coupled quantum wells at high magnetic field: the role of disorder
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
Collective properties of a quasi-two-dimensional (2D) system of spatially indirect magnetoexcitons in coupled quantum wells (CQW) in high magnetic field were analyzed in the pr…
Collective properties of indirect excitons in coupled quantum wells in random field
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
The influence of a random field induced by impurities, boundary irregularities etc. on the superfluidity of a quasi-two-dimensional (2D) system of spatially indirect excitons in co…
Superfluidity of "dirty" indirect excitons in coupled quantum wells
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
The theory of what happens to a superfluid in a random field, known as the ``dirty boson'' problem, directly relates to a real experimental system presently under study by several…
