Per-Olov Löwdin
Per-Olov Löwdin (28 Ocak 1916 - 6 Ocak 2000) İsveçli fizikçi, Uppsala Üniversitesi'nde profesör (1960'tan 1983'e kadar), paralel olarak 1993'e kadar Florida Üniversitesi'nde profesör.
Ivar Waller adı altındaki eski lisans öğrencisi, Löwdin 1950 yılında moleküler orbital hesaplamalar için simetrik ortogonalizasyon düzenlemeleri yapmıştır. Bu şema Yarı-ampirik teorileri kullanılan sıfır diferansiyel örtüşme (ZDO) yaklaşım temelidir. Löwdin ayrıca kolay kuantum mekaniğinin çeşitli teoremlerin türetmelerini matrisleri için sembolleri kullanarak oluşturmuştur.
ROHF,UHF ve RES-GVB teorilerinde kullanılan meşhur “Löwdin’s pairing theorem” onun değildir. Kendisine göre George G. Hall ve King Löwdin 'in resmi olmayan önerisinden sonra resmi bir sunum yapmışlardır.
1963 ve 1971 yılları arasında yayınlanmış pertürbasyon teorisi üzerindeki 14 sayfa dizi kuantum kimyası için en iyi bölümleme tekniği olarak görülmüştür.
Löwdin ayrıca 1958 yılında Uppsala'da kuantum kimyası yaz okulundan başlayarak çok etkili ve aktif bir öğretmendir. 1958 ve 1960'ta Uppsala Üniversitesi kuantum kimyası grubuna kardeş olarak Florida Üniversitesi'nde kuantum teorisi projesine başlamıştır. Uluslararası Kış Enstitüleri (başlarda Sanibel adasında olan daha sonra Gainesville alınan) yüzlerce Latin Amerikanların seksenler ve doksanlar boyunca katılımlarını sağladı. 1960 yılında Kış Enstitüsünün içindeki birleşimde Sanibel sempozyumunu kurdu. 1960'tan sonra her yıl düzenlenmiştir.
Löwdin 1969'da İsveç Kraliyet Bilimler Akademisi üyesi olarak seçilmiş ve 1972'den 1984'e kadar Fizik Nobel Ödülü komitesinde bulunmuştur. Kuantum kimyası uluslararası gazetesi ve kuantum kimyası gelişmeler serisi kurucudur. Uluslararası Kuantum Moleküler Bilimler Akademisi'nin de vakıf üyesidir.
