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
