    • Exciton condensate driven force in double layer systems 

      Özgün, Ege (Bilkent University, 2016-02)
      Excitonic systems are challenging to deal with both theoretically and experimentally but in return, they offer a very rich physics and exotic features. We will investigate their properties under weak magnetic field and ...

    • Four-channel parity-time symmetry 

      Özgün, Ege; Özbay, Ekmel; Ozdur, Ibrahim (Institute of Physics Publishing, 2022)
      In this letter, we propose a general scheme for four-channel parity-time symmetry. We theoretically demonstrate how to achieve novel features via exploiting the parity-time symmetry for four-channel coupled-mode equations ...

    • Robust ground state and artificial gauge in DQW exciton condensates under weak magnetic field 

      Hakioǧlu, Tuğrul; Özgün, Ege; Günay, Mehmet (Elsevier B.V., 2014)
      An exciton condensate is a vast playground in studying a number of symmetries that are of high interest in the recent developments in topological condensed matter physics. In double quantum wells (DQWs) they pose highly ...

    • Scattering of spin-1/2 particles from a PT-symmetric complex potential 

      Özgün, Ege; Hakioğlu, T.; Özbay, Ekmel (IOP, 2020)
      In this letter, we study the scattering of spin- 1 2 particles from a spin-independent parity time (PT )-symmetric complex potential, and for the first time, theoretically demonstrate the coexistence of PT -symmetric and ...

    • A simple parity-time-symmetric optoelectronic oscillator based on all-fiber coupling 

      Özgün, Ege; Uyar, Faruk; Kartaloǧlu, Tolga; Özbay, Ekmel; Ozdur, İ. T. (The Optical Society, 2021)
      We experimentally demonstrate a simple parity-time-symmetric optoelectronic oscillator based on all-fiber coupling with single-mode microwave oscillation at 9.5 GHz possessing a phase noise value of −116.2 dBc/Hz at 10 kHz offset.
