DESCRIPTION:Abstract\nFor over a century\, physicists have dreamed of achi
 eving room-temperature superconductivity—a state where electricity flows
  without resistance and magnetic fields are expelled. One of the most prom
 ising paths to realizing this dream lies in hydrogen\, the simplest and mo
 st abundant element in the universe. Theoretical predictions long suggeste
 d that hydrogen in its solid phase\, when subjected to extreme pressures\,
  would transform into a metallic state and exhibit high-temperature superc
 onductivity. However\, for decades\, the required pressures remained far b
 eyond experimental reach.\nRecently\, breakthrough experiments have begun 
 to provide evidence that solid hydrogen becomes metallic around 400–500 
 GPa\, though the nature of this metallization remains mysterious. Meanwhil
 e\, researchers have discovered a more accessible route: incorporating hyd
 rogen into other elements to form hydride compounds. These materials have 
 already shattered superconducting temperature records\, with sulfur hydrid
 e reaching 200 K in 2015 and lanthanum hydride surpassing 250 K in 2019—
 both at significantly lower pressures than pure hydrogen.\nIn this talk\, 
 I will explore the latest advances in high-pressure hydrogen and hydride s
 uperconductors\, the challenges in explaining metallic hydrogen\, and the 
 strategies guiding the search for superconductors that operate at room tem
 perature and\, ultimately\, at practical pressures—an “ambient” supe
 rconductor. Could we be on the verge of a revolution in energy transmissio
 n\, magnetic levitation\, and quantum technology? The race for the ultimat
 e superconductor is heating up\, and hydrogen is at its core.\n\nBio\nDr. 
 Mehmet Doğan is a computational materials physicist specializing in first
 -principles methods. His research focuses on quantum materials\, low-dimen
 sional systems\, superconductors\, and large finite systems\, combining hi
 gh-performance computing with scientific machine learning techniques.\nHe 
 received his B.S. in Physics & Mathematics from Middle East Technical Univ
 ersity and his Ph.D. in Physics from Yale University. He has worked as a r
 esearcher at UC Berkeley and UT Austin. Since 2025\, he has been serving a
 s an Assistant Professor of Physics at San Diego State University.\n\n \n
