演示了原子电池的操作，其中存储在双阱势的一半中的有限温度玻色-爱因斯坦凝聚体与初始空负载阱耦合，该负载阱的阻抗与谐振终端束相匹配。在放电循环中监测冷凝液的原子序数和温度，并用于计算电池的基本性质。根据Thevenin等效电路对放电行为进行了分析，该电路包含有限内阻以考虑电池的耗散。在多种放电速率下，电池性能的特征是峰值输出功率、系统的电流和能量容量。
Operation of an atomtronic battery is demonstrated where a finite-temperature Bose-Einstein condensate stored in one half of a double-well potential is coupled to an initially empty load well that is impedance matched by a resonant terminator beam. The atom number and temperature of the condensate are monitored during the discharge cycle, and are used to calculate fundamental properties of the battery. The discharge behavior is analyzed according to a Thevenin equivalent circuit that contains a finite internal resistance to account for dissipation in the battery. Battery performance at multiple discharge rates is characterized by the peak power output, and the current and energy capacities of the system.
