    Abstract: Systems and methods for zero power automatic thermal regulation are provided. In one embodiment, a method for passive thermal management comprises: establishing thermal conductivity between a self-heating electronic device and a cooling fluid held within a fluid reservoir via a thermal interface; using thermally controlled expansion of the cooling fluid, controlling a length of a column of the cooling fluid extending into at least one channel extending from the fluid reservoir, wherein the channel provides a non-recirculating path for the cooling fluid to expand into, and wherein the length of a column of the cooling fluid is thermally controlled using heat absorbed by the cooling fluid from the self-heating electronic device; and selectively establishing a primary heat path between the electronic device and a heat sink interface thermally coupled to an external environment as a function of the length of the column of the cooling fluid within the channel.

    Abstract: Systems and methods for eliminating multi-path errors from atomic inertial sensors are provided. In certain embodiments, a system for performing atom interferometry includes a vacuum cell containing multiple atoms and a first plurality of lasers configured to trap the atoms within the vacuum cell. The system further includes a second plurality of lasers configured to impart momentum to the atoms and direct the atoms down multiple paths, wherein a primary path in the multiple paths has a first and second component that converge at a converging point, wherein a diverging part of the primary path in which the first and second components are diverging is asymmetrical with respect to a converging part of the primary path in which the first and second components are converging, such that only the first and second components converge at the converging point wherein other paths do not converge at the converging point.

    Abstract: Waveguide includes fork with first and second bifurcated ends coupled to loop section and separated by angle determined based on velocities of portions of quantum mechanical wavefunction of atoms traveling above waveguide. Waveguide propagates blue-detuned laser having first evanescent field that repels atoms away from waveguide and red-detuned laser having second evanescent field that attracts atoms toward waveguide, together creating potential minimum/well. Laser cooling atoms, causing atoms positioned in potential minimum/well to move toward first fork section following potential minimum/well. Atomic state initialization section initializes atomic states of atoms to known ground-state configuration. Beam splitter section splits quantum mechanical waveform of each atom above surface of diverging waveguide into first portion at first velocity that travels into first end of first fork section into first loop section and second portion at second velocity that travels into second end of first fork section into first loop section.

    Abstract: Methods are provided for authenticating a value article that includes a luminescent material. An exciting light source, an optical filter, a photodetector, a signal manipulation circuit, and an amplifier are provided. The luminescent material is exposed to light produced by the exciting light source. Radiation including light from the exciting light source and emitted radiation from the luminescent material is filtered using the optical filter to produce filtered radiation. The filtered radiation is detected using the photodetector to produce a detected radiation signal. The detected radiation signal is electronically manipulated using the signal manipulation circuit to reduce an effect of light from the exciting light source on an authentication determination based upon the detected radiation signal. The detected radiation signal is amplified with the amplifier after electronic manipulation to produce an amplified electronic signal. The amplified electronic signal or data derived therefrom is converted to an authentication output.

    Abstract: A method for measuring the population of atoms in a vapor cell comprises collecting a sample of atoms, applying radio frequency (RF) spectroscopy to the sample such that a first portion of the atoms are in an upper ground state and a second portion of the atoms are in a lower ground state, and applying light to the sample to produce a first fluorescence such that all atoms are left in the lower ground state. The method further comprises measuring a population of the atoms in the upper ground state based on the first fluorescence, applying an RF pulse to the sample to transfer the atoms in the lower ground state to the upper ground state, and applying light to the sample after the RF pulse is applied to produce a second fluorescence. A population of all the atoms in the sample is then measured based on the second fluorescence.
