DESCRIPTION:Speaker: Guanchen Peng\nhosted by Onur Hosten\nAbstract: Altern
 ating the propagation direction of the Raman light (k-reversal) has been e
 ssential for implementing traditional large momentum transfer (LMT) for a 
 Raman atom interferometer\, where a series of light pulses are used to per
 form both /2-pulse and -pulse. In this talk\, I will present our method of
  performing LMT without k-reversal [1]. We use microwave /2-pulse and Rama
 n -pulse to perform LMT\, which uses the same principle as shown in the or
 iginal Spin-Dependent-Kick interferometer [2]. However\, we applied an add
 itional microwave  pulse in the middle of the interferometer sequence to r
 everse the spin states\, which allows closing of the interferometer arms b
 y the same Raman light -pulses without k-reversal. I will present a proof-
 of-principle demonstration of a 4hk atom interferometer and discuss its sc
 alability to 4Nhk. I will discuss the complicated feature due to the non-u
 nity fidelity of Raman pulses. I will also comment on the connection betwe
 en our scheme and the Bragg atom optics. [1] G. Peng \, B. Lanigan \, R. S
