Manufacturing a thin wire electrostatic trap (TWIST) for ultracold polar molecules
We present a detailed description on how to build a Thin WIre electroStatic
Trap (TWIST) for ultracold polar molecules. It is the first design of an
electrostatic trap that can be superimposed directly onto a magneto optical
trap (MOT). We can thus continuously produce ultracold polar molecules via
photoassociation from a two species MOT and instantaneously trap them in the
TWIST without the need for complex transfer schemes. Despite the spatial
overlap of the TWIST and the MOT, the two traps can be operated and optimized
completely independently due to the complementary nature of the utilized
trapping mechanisms.Comment: 5 pages, 8 figures, updated conten
Trapping of ultracold polar molecules with a Thin Wire Electrostatic Trap
We describe the realization of a dc electric-field trap for ultracold polar
molecules, the thin-wire electrostatic trap (TWIST). The thin wires that form
the electrodes of the TWIST allow us to superimpose the trap onto a
magneto-optical trap (MOT). In our experiment, ultracold polar NaCs molecules
in their electronic ground state are created in the MOT via photoassociation,
achieving a continuous accumulation in the TWIST of molecules in low-field
seeking states. Initial measurements show that the TWIST trap lifetime is
limited only by the background pressure in the chamber.Comment: 4 pages, 3 figure
Public Policy Concerns Prevent Application of Comity to Foreign Bankruptcy Proceedings That Discriminate Against Tax Obligations Owed to the United States Government
This Case Comment explores the application of comity to foreign bankruptcy proceedings, particularly when comity would render the Internal Revenue Service a general unsecured creditor in bankruptcy. The United States Court of Appeals for the Fifth Circuit held on public policy grounds that comity should not be accorded to a Luxembourg bankruptcy proceeding that discriminated against tax obligations owed to the United States government. This Case Comment discusses the factual setting for the instant decision and presents a brief history of transnational insolvency law. The author finds that the law of transnational insolvency is inconsistent and underdeveloped and that the instant decision furthers the territoriality approach towards international bankruptcy under which United States courts refuse to recognize foreign bankruptcy proceedings. The author concludes that in today\u27s global economy such an approach is unworkable, and that the United States must adopt the universality approach towards transnational insolvency in order to encourage foreign tribunals to recognize United States bankruptcy proceedings and to facilitate the reorganization of multinational corporations
